The current epidemiology of SIDS in Ireland.

This paper examines some epidemiological factors associated with SIDS to give a general profile of SIDS cases occurring in Ireland between the years 1993 to 1997. There has been a dramatic decrease in the incidence of the Sudden Infant Death Syndrome (SIDS) in the Republic of Ireland in the last decade from an average rate of 2.2/1000 live-births in the 1980s to 0.8/1000 live-births in the years 1993-1997, a decrease of 100 deaths a year. The fall in the SIDS rate has been seen in many countries and is felt to be associated with Reduce The Risks (RTR) of SIDS campaigns and the avoidance of the prone sleeping position. The use of the prone sleep position averaged at 6% of children being put prone in the years 1993-1997 but the prone position has progressively decreased from 13% of children being put prone in 1994 to only 2% in 1997. The profile of the Irish SIDS cases is similar to that of SIDS cases in other countries following similar RTR campaigns with a male predominance, the characteristic clustering of deaths in the first six months of life and the majority of cases (75%) occuring in the night sleep period. The loss of the seasonal variation of the time of death is also shown and factors such as lower socio-economic status, unemployment and medical card eligibility were seen in higher proportions in SIDS families than in the general population. A high percentage of SIDS mothers smoked (73%). Higher smoking rates were seen among younger and single mothers and smoking rates were inversely related to educational level and socioeconomic grouping. An urgent question that needs to be addressed is how socioeconomic disadvantage increases the SIDS risk and what factors influence socioeconomically disadvantaged families to adopt life style and parenting practices such as smoking that influence their children's health.

SIDS risk factor awareness: assessment among nursing students.

OBJECTIVE: To test the hypotheses that nursing students (a) have limited knowledge of risk factors for sudden infant death syndrome (SIDS) and the American Academy of Pediatrics (AAP) recommendation of placing infants on their backs or sides for sleep, and (b) after careful education about SIDS, would retain this information and teach it to parents. DESIGN: A pretest questionnaire was used to identify knowledge of 13 risk factors and personal recommendation for sleep position. Participants attended a lecture on SIDS and received written educational material. A posttest was completed after 6 weeks. SETTING: Nursing students were assessed during their family practice course. PARTICIPANTS: Fifty-one 4th-year nursing students (mean age 28.4 years, SD=7.6) enrolled in the BSN program completed the pretest; 29 completed the identical posttest. INTERVENTION: A lecture on SIDS and SIDS risk factors with written educational material after the pretest. MAIN OUTCOME MEASURES: Pretest and posttest responses. RESULTS: The Mann-Whitney test and McNemar chi-square analyses were used to determine factors on the pretest which influenced the awareness of prone position and to compare pretest and posttest data. On the pretest, 69% of students were aware of the AAP recommendation but significantly more (92%) were aware on the posttest. Posttest responses increased significantly for 12 of the 13 risk factors; 41% of the students identified all 13 risk factors on the posttest, in contrast to 0% on the pretest. On both the pretest and posttest, 93% of students stated that it was important to discuss their infant's sleep position with parents. Posttest results showed that students unanimously recommend the side or back sleep position. CONCLUSION: Nursing students were aware of the AAP recommendation, yet their knowledge of other risk factors was limited. A careful educational process resulted in retention of information about the AAP recommendation and other risk factors. In addition, students were willing to teach parents to place their infants on the back or side to sleep.

Estimation of transmural cardiac pressures during ventilation with PEEP.

Assessment of ventricular performance during positive end-expiratory pressure (PEEP) requires accurate measurement of transmural cardiac pressures. We investigated the influence of PEEP on the atrial and juxtacardiac pressures estimated by different methods in eight dogs. Left atrial pressure was measured by hydraulic and transducer-tipped catheter systems. Juxtacardiac pressure was estimated by an esophageal balloon and by air- and fluid-filled mediastinal wafer sensors. The supine canine heart was observed radiographically to lift and tilt during PEEP subjecting the left atrial catheters and the fluid-filled mediastinal wafer to a hydrostatic pressure increase. The esophageal balloon seriously underestimated the pressure increment occurring during the application of PEEP in the supine (but not prone) position, perhaps because mediastinal weight was lifted from the esophagus during lung distension. Similar phenomena were also observed in three human subjects. We conclude that lung distension lifts and tilts the heart in a supine preparation causing a hydrostatic increase of intracavitary pressure and attenuation of the esophageal pressure increment. These effects help to account for the apparent alterations of ventricular compliance and performance previously attributed to PEEP.

Computed tomography in adult respiratory distress syndrome: what has it taught us?

Computed tomography (CT) has played an important role in improving our knowledge of the pathophysiology of the adult respiratory distress syndrome (ARDS), and in determining the morphological and functional relationships of different manoeuvres commonly used in the therapeutic management of this syndrome (changes in body position, application of positive end-expiratory pressure (PEEP) and mechanical ventilation). During the early phase of the disease, the ARDS lung is characterized by a homogenous alteration of the vascular permeability. Thus, oedema accumulates evenly in all lung regions with a nongravitational distribution (homogenous lung). The increased lung weight, due to increased oedema, causes a collapse of the lung regions along the vertical axis, through the transmission of hydrostatic forces (compression atelectasis). Thus, the lesions appear mainly in the dependent lung regions (dishomogeneous lung). During inspiration, at plateau pressure, the pulmonary units reopen and, if the PEEP applied is adequate, they stay open during the following expiration. Adequate PEEP is equal to or higher than the hydrostatic forces compressing that unit. Prone position is another manoeuvre which allows previously collapsed lung regions to reopen and, conversely, compresses previously aerated regions, reversing the distribution of gravitational forces. During late ARDS, there is less compression atelectasis and the lung undergoes structural changes, due to the reduced amount of oedema. This is usually associated with CO2 retention and the development of emphysema-like lesions. In conclusion, computed tomography is not only a research tool, but a useful technique which allows a better understanding of the progressive change in strategy needed to ventilate the adult respiratory distress syndrome lung at different stages of the disease.

A prospective study of three postural reactions.

In order to assess the evolution of postural reactions in the prone position, a group of 149 normal infants were followed from birth to two years of age. The Landau reflex was present in 44 per cent of two-month-old infants, and in 95 per cent at four months. The tonic labyrinthine response (grades 2 to 4) was seen in 80 per cent of infants at two weeks, with a marked diminution by the age of 24 months. In contrast, the symmetrical tonic neck reflex was detected in fewer than 30 per cent of the infants: the maximum prevalence was at four to six months of age. These findings are consistent with the hypothesis that the Landau is an early righting reflex which emerges after, and is independent of, the tonic labyrinthine response in prone and the symmetrical tonic neck reflex.

Innovative practices of ventilatory support with pediatric patients.

OBJECTIVES: The recognition that alveolar overdistension rather than peak inspiratory airway pressure is the primary determinant of lung injury has shifted our understanding of the pathogenesis of ventilator-induced side effects. In this review, contemporary ventilatory methods, supportive treatments, and future developments relevant to pediatric critical care are reviewed. DATA SYNTHESIS: A strategy combining recruitment maneuvers, low-tidal volume, and higher positive end-expiratory pressure (PEEP) decreases barotrauma and volutrauma. Given that appropriate tidal volumes are critical in determining adequate alveolar ventilation and avoiding lung injury, volume-control ventilation with high PEEP levels has been proposed as the preferable protective ventilatory mode. Pressure-related volume control ventilation and high-frequency oscillatory ventilation (HFOV) have taken on an important role as protective lung strategies. Further data are required in the treatment of children, confirming the preliminary results in specific lung pathologies. Spontaneous breathing supported artificially during inspiration (pressure support ventilation) is widely used to maintain or reactivate spontaneous breathing and to avoid hemodynamic variation. Volume support ventilation reduces the need for manual adaptation to maintain stable tidal and minute volume and can be useful in weaning. Prone positioning and permissive hypercapnia have taken on an important role in the treatment of patients undergoing artificial ventilation. Surfactant and nitric oxide have been proposed in specific lung pathologies to facilitate ventilation and gas exchange and to reduce inspired oxygen concentration. Investigation of lung ventilation using a liquid instead of gas has opened new vistas on several lung pathologies with high mortality rates. RESULTS: The conviction emerges that the best ventilatory treatment may be obtained by applying a combination of types of ventilation and supportive treatments as outlined above. Early treatment is important for the overall positive final result. Lung recruitment maneuvers followed by maintaining an open lung favor rapid resolution of pathology and reduce side effects. CONCLUSIONS: The methods proposed require confirmation through large controlled clinical trials that can assess the efficacy reported in pilot studies and case reports and define the optimal method(s) to treat individual pathologies in the various pediatric age groups.

Severe pneumothorax after intercostal nerve blockade. A case report.

BACKGROUND: Intercostal nerve blockade is recognized as an efficient and safe regional anesthetic technique. Although an appropriate technique was applied, we report a severe pneumothorax associated with this type of regional anesthesia. METHODS: A 57-year-old female patient underwent block of intercostal nerves 3 to 8 for interstitial radiotherapy of the left breast in the sitting position. Calcified residual foci in the right upper lobe from a previous primary infection of tuberculosis were diagnosed by preoperative x-ray. After completion of the blocks in the midline of the axilla, the patient complained of pain between the scapulas, developed severe dyspnea and panic, and felt as if her life was in jeopardy. A severe pneumothorax was diagnosed and a chest tube was placed. After the application of the chest tube, the patient recovered quickly. CONCLUSION: Extra caution should be used in applying this procedure to patients with underlying chronic lung disease, especially on the opposite side. Our case demonstrates that in all patients undergoing intercostal nerve blockade preference should be given to the approach at the dorsal angulation of the rib in the lateral or prone position due to its lower risk of pneumothorax.

Diagnostic accuracy of gated Tc-99m sestamibi stress myocardial perfusion SPECT with combined supine and prone acquisitions to detect coronary artery disease in obese and nonobese patients.

BACKGROUND: The diagnostic value of gated myocardial perfusion single-photon emission computed tomography (MPS) with combined supine and prone acquisitions to detect coronary artery disease (CAD) in obese and nonobese patients has not been defined. METHODS AND RESULTS: We studied 1511 patients without prior myocardial infarction or coronary revascularization who either had coronary angiography within 3 months of MPS (n = 785) or had a low pretest likelihood of CAD (n = 726). All patients underwent rest thallium 201/gated exercise or adenosine stress technetium 99m sestamibi MPS in both the supine and prone positions. According to body mass index (BMI), patients were categorized as normal weight (BMI of 18.5-24.9 kg/m2), overweight (BMI of 25.0-29.9 kg/m2), or obese (BMI > or = 30.0 kg/m2). There were no significant differences in stress, fixed, or ischemic defects among patients in different weight categories. The sensitivity of MPS was 85%, 86%, and 89% for detecting patients with 50% or greater coronary stenosis and 89%, 91%, and 92% for detecting those with 70% or greater coronary stenosis in the normal-weight, overweight, and obese groups, respectively. Normalcy rates were nearly identical among the 3 weight groups (99%, 98%, and 99%, respectively). Multivariate logistic regression analysis further confirmed that BMI was a nonsignificant predictor for the detection of CAD. In a subset of 290 patients, automated quantitative MPS analysis confirmed that combined supine and prone MPS increased specificity (86%) in identifying CAD, without a significant reduction in sensitivity (83% for > or = 50% stenosis and 88% for > or = 70% stenosis). CONCLUSION: The findings of this study suggest that MPS performed with gating and combined supine and prone acquisitions without attenuation correction had a similar diagnostic accuracy for the detection of CAD in normal-weight, overweight, and obese patients.

Massive-training artificial neural network (MTANN) for reduction of false positives in computer-aided detection of polyps: Suppression of rectal tubes.

One of the limitations of the current computer-aided detection (CAD) of polyps in CT colonography (CTC) is a relatively large number of false-positive (FP) detections. Rectal tubes (RTs) are one of the typical sources of FPs because a portion of a RT, especially a portion of a bulbous tip, often exhibits a cap-like shape that closely mimics the appearance of a small polyp. Radiologists can easily recognize and dismiss RT-induced FPs; thus, they may lose their confidence in CAD as an effective tool if the CAD scheme generates such "obvious" FPs due to RTs consistently. In addition, RT-induced FPs may distract radiologists from less common true positives in the rectum. Therefore, removal RT-induced FPs as well as other types of FPs is desirable while maintaining a high sensitivity in the detection of polyps. We developed a three-dimensional (3D) massive-training artificial neural network (MTANN) for distinction between polyps and RTs in 3D CTC volumetric data. The 3D MTANN is a supervised volume-processing technique which is trained with input CTC volumes and the corresponding "teaching" volumes. The teaching volume for a polyp contains a 3D Gaussian distribution, and that for a RT contains zeros for enhancement of polyps and suppression of RTs, respectively. For distinction between polyps and nonpolyps including RTs, a 3D scoring method based on a 3D Gaussian weighting function is applied to the output of the trained 3D MTANN. Our database consisted of CTC examinations of 73 patients, scanned in both supine and prone positions (146 CTC data sets in total), with optical colonoscopy as a reference standard for the presence of polyps. Fifteen patients had 28 polyps, 15 of which were 5-9 mm and 13 were 10-25 mm in size. These CTC cases were subjected to our previously reported CAD scheme that included centerline-based segmentation of the colon, shape-based detection of polyps, and reduction of FPs by use of a Bayesian neural network based on geometric and texture features. Application of this CAD scheme yielded 96.4% (27/28) by-polyp sensitivity with 3.1 (224/73) FPs per patient, among which 20 FPs were caused by RTs. To eliminate the FPs due to RTs and possibly other normal structures, we trained a 3D MTANN with ten representative polyps and ten RTs, and applied the trained 3D MTANN to the above CAD true- and false-positive detections. In the output volumes of the 3D MTANN, polyps were represented by distributions of bright voxels, whereas RTs and other normal structures partly similar to RTs appeared as darker voxels, indicating the ability of the 3D MTANN to suppress RTs as well as other normal structures effectively. Application of the 3D MTANN to the CAD detections showed that the 3D MTANN eliminated all RT-induced 20 FPs, as well as 53 FPs due to other causes, without removal of any true positives. Overall, the 3D MTANN was able to reduce the FP rate of the CAD scheme from 3.1 to 2.1 FPs per patient (33% reduction), while the original by-polyp sensitivity of 96.4% was maintained.

Infant sleep position instruction and parental practice: comparison of a private pediatric office and an inner-city clinic.

OBJECTIVE: To determine infant sleep instructions that hospital personnel in our community were giving to parents and actual positions practiced after the April 15, 1992 American Academy of Pediatrics recommendation for nonprone positioning. DESIGN: Survey of mothers of infants </=4 months of age from November 1993 to March 1994 with follow-up survey of selected birth hospitals. SETTING: A private practice (PP) serving predominantly white middle- and upper-income children and a pediatric clinic (CY) serving inner-city predominantly African-American low-income children in Louisville, Kentucky. PATIENTS: Fifty infants from each practice site. OUTCOME MEASURE: The sleep instructions given and practiced, and other risk factors for sudden infant death syndrome (SIDS). RESULTS: Nonprone sleeping instructions were received by 72% of the PP and only 48% of the CY parents, with 72% of the PP and 54% of the CY following the nonprone recommendations. Infants were more likely to be in smoking households (60% vs 12%) from the CY practice than the PP practice. CONCLUSIONS: Our study showed that, despite having a higher prevalence of SIDS risk factors, there was a greater delay in discontinuing prone positioning instructions in the hospital serving the CY infants. The evidence suggests that this population is as likely as the PP group to follow medical advice given.

Carbon dioxide tensions in manually ventilated, prone patients.

The distribution of arterial carbon dioxide tensions (PaCO2) in 288 anaesthetized, healthy patients in the prone position was investigated during non-monitored manual ventilation. Four equal groups of 72 patients were compared employing a conventional anaesthetic system with and without CO2-absorption and a modified Mapleson D rebreathing system using high and low fresh gas flows. No fundamental difference between the Mapleson D system and the circle system without CO2-absorption could be demonstrated. With the Mapleson D system a high fresh gas flow resulted in a loss of rebreathing characteristics, the scatter of PaCO2-values then approaching that of a conventional circle system with CO2-absorption. The results demonstrate that during manual ventilation a CO2-absorption results in unpredictable levels of PaCO2 with unacceptably wide ranges. On the other hand, prevention of hypocapnia could be obtained with the rebreathing systems using a low fresh gas flow. Hypercapnia was modest and similar in all groups, PaCO2 never exceeding 7.3 kPa. In terms of PaCO2-levels it seems, compared to recent literature, of no importance whether the patient is prone or supine or whether or not ventilation is monitored, performed by hand or by means of anaesthetic ventilators. Accurate levels of PaCO2 can probably only be obtained by frequent analyses of PaCO2, or monitoring of the end-tidal CO2 concentration.

Differences in infant and parent behaviors during routine bed sharing compared with cot sleeping in the home setting.

OBJECTIVES: To observe the behavior of infants sleeping in the natural physical environment of home, comparing the 2 different sleep practices of bed sharing and cot sleeping quantifying to factors that have been identified as potential risks or benefits. METHODS: Forty routine bed-sharing infants, aged 5-27 weeks were matched for age and season of study with 40 routine cot-sleeping infants. Overnight video and physiologic data of bed-share infants and cot-sleep infants were recorded in the infants' own homes. Sleep time, sleep position, movements, feeding, blanket height, parental checks, and time out of the bed or cot were logged. RESULTS: The total sleep time was similar in both groups (bed-sharing median: 8.6 hours; cot-sleeping median: 8.2 hours). Bed-sharing infants spent most time in the side position (median: 5.7 hours, 66% of sleep time) and most commonly woke at the end of sleep in this position, whereas cot-sleeping infants most commonly slept supine (median: 7.5 hours, 100%) and woke at the end of sleep in the supine position. Prone sleep was uncommon in both groups. Head covering above the eyes occurred in 22 bed-sharing infants and 1 cot-sleeping infant. Five of these bed-sharing infants were head covered at final waking time, but the cot-sleeping infant was not. Bed-sharing parents looked at or touched their infant more often (median: 11 vs 4 times per night) but did not always fully wake to do so. Movement episodes were shorter in the bed-sharing group as was total movement time (37 vs 50 minutes respectively), whereas feeding was 3.7 times more frequent in the bed-sharing group than the cot-sleeping group. CONCLUSIONS: Bed-share infants without known risk factors for sudden infant death syndrome (SIDS) experience increased maternal touching and looking, increased breastfeeding, and faster and more frequent maternal responses. This high level of interaction is unlikely to occur if maternal arousal is impaired, for example, by alcohol or overtiredness. Increased head covering and side sleep position occur during bed-sharing, but whether these factors increase the risk of SIDS, as they do in cot sleeping, requires further investigation.

Birth weight- and gestational age-specific sudden infant death syndrome mortality: United States, 1991 versus 1995.

OBJECTIVE: To estimate the changes in birth weight- and gestational age-specific sudden infant death syndrome (SIDS) mortality rates since the publication of the sleep-positioning recommendations by the American Academy of Pediatrics Task Force on Infant Positioning and SIDS. METHODS: This is a historical cohort study using US vital statistic linked birth and infant death certificate files for the years 1991 and 1995. SIDS deaths were identified as any death attributed to International Classification of Diseases, Ninth Revision code 7980, occurring between the 28th and 365th days of life. RESULTS: There were 4871 deaths attributed to SIDS in 1991 for a postneonatal mortality rate of 1.2/1000 postneonatal survivors compared with 3114 deaths in 1995 for a rate of.8/1000. This represents a 33% drop in the postneonatal SIDS mortality from 1991 to 1995. Between 1991 and 1995, SIDS rates declined 38%, 38%, 35%, and 32% for birth weight groupings of 500 to 999 g, 1000 to 1499 g, 1500 to 2499 g, and >/=2500 g, respectively. There were no SIDS deaths attributed to infants weighing <500 g. The SIDS rates declined 27%, 21%, 40%, and 23% for gestational age groups of <29 weeks, 29 to 32 weeks, 33 to 36 weeks, and >/=37 weeks. The rate of decline did not differ significantly across birth weight- or gestational age-specific categories. There was a significant increase in the black:non-black postneonatal SIDS mortality ratio from 2.00 to 2.28, reflecting a smaller decline in birth weight- and gestational age-specific mortality for blacks than observed for the non-black population. CONCLUSION: Postneonatal SIDS mortality decreased significantly across all broad birth weight and gestational age categories. If the decline in the prevalence of prone positioning that has been reported since 1992 has occurred across all birth weight and gestational age, these data support the hypothesis that supine or side sleep positioning is effective in preterm/low birth weight infants as well as term infants.

Retinal tears 180 degrees and greater. Management with vitrectomy and intravitreal gas.

A new technique for the treatment of giant retinal dialysis of 180 degrees or more has been devised. After the lens and vitreous have been removed via the pars plana, the patient is rotated into a prone position on a special operating table. The retina is unfolded by filling the eye completely with gas and is held in place by gas. The patient is then brought back into the normal supine position, and a scleral encircling procedure is added. The initial success rate of reattachment is 12 out of 14 cases. Afterward, many eyes develop massive periretinal proliferation. After six months or more of follow-up, the retina remained attached in six of 14 cases.

Retinal microincarceration with penetrating diathermy in the management of giant retinal tears.

A technique for repair of giant retinal breaks with detachment involves the performance of lensectomy-sector iridectomy, vitrectomy, and scleral buckling behind the equator. Total fluid-gas exchange is performed while the patient is turned to the prone position on a rotating table. Penetrating diathermy is used to fix the retina and to create retinal microincarceration while air is simultaneously injected into the eye.

A simplified method of treating retinal detachment with macular hole. Long-term follow-up.

Eighteen patients with macular hole retinal detachment and no visible posterior vitreoretinal connections were treated by one of two methods. In ten patients with extensive retinal detachment, the subretinal fluid was released in the temporal scleral side, and 1.0 mL or more of air or gas was injected into the vitreous cavity through the pars plana. In eight patients with localized retinal detachment in the posterior pole, 0.7 mL or more of gas was injected into the vitreous cavity after 0.3 to 0.5 mL of aqueous humor was released. Macular buckling, macular diathermy, or vitrectomy was not used. After the operation, the patients were placed in a prone position for at least six hours a day until the air or gas disappeared from the vitreous cavity. In 15 of 18 patients, the retina remained attached during follow-up periods that ranged from four to 32 months (average, 14 months). This operation is easy and safe and requires no sophisticated instruments. In addition, the macula is not damaged, as it can be by diathermy and buckling. This procedure should be the treatment of choice in patients with retinal detachments with macular holes but without other breaks or visible vitreous adhesion.

Kangaroo care is effective in diminishing pain response in preterm neonates.

OBJECTIVE: To test the efficacy of maternal skin-to-skin contact, or kangaroo care (KC), on diminishing the pain response of preterm neonates to heel lancing. DESIGN: A crossover design was used, in which the neonates served as their own controls. Subjects Preterm neonates (n = 74), between 32 and 36 weeks' postmenstrual age and within 10 days of birth, who were breathing without assistance and who were not receiving sedatives or analgesics in 3 level II to III neonatal intensive care units in Canada. INTERVENTIONS: In the experimental condition, the neonate was held in KC for 30 minutes before the heel-lancing procedure and remained in KC for the duration of the procedure. In the control condition, the neonate was in the prone position in the isolette. The ordering of conditions was random. MAIN OUTCOME MEASURES: The primary outcome was the Premature Infant Pain Profile, which is composed of 3 facial actions, maximum heart rate, and minimum oxygen saturation changes from baseline in 30-second blocks. Videotapes, taken with the camera positioned on the neonate's face so that an observer could not tell whether the neonate was being held or was in the isolette, were coded by research assistants who were naïve to the purpose of the study. Heart rate and oxygen levels were continuously monitored into a computer for later analysis. A repeated-measures analysis of covariance was used, with order of condition and site as factors and severity of illness as a covariate. RESULTS: Premature Infant Pain Profile scores across the first 90 seconds from the heel-lancing procedure were significantly (.002<P<.04) lower by 2 points in the KC condition. CONCLUSIONS: For preterm neonates who are 32 weeks' postmenstrual age or older, KC seems to effectively decrease pain from heel lancing. Further study is needed to determine if younger neonates or those requiring assistance in breathing, or older infants or toddlers, would benefit from KC, or if it would remain effective over several procedures. Given its effectiveness, and that parents of neonates in critical care units want to participate more in comforting their children, KC is a potentially beneficial strategy for promoting family health.
