Risk factors of failure and immediate complication of subclavian vein catheterization in critically ill patients.

OBJECTIVE: To identify the risk factors of failure and immediate complication of subclavian vein catheterization (SVC). DESIGN: Prospective observational study. SETTING: Surgical critical care unit of a tertiary university hospital. PATIENTS: Critically ill patients requiring a first SVC. INTERVENTION: Subclavian vein catheterization was attempted in 707 patients without histories of surgery or radiotherapy in the subclavian area. Failed catheterizations, arterial punctures, pneumothoraces and misplacements of the catheter tip were recorded. Risk factors of failure and immediate complication were isolated among patients' characteristics, procedure parameters (side and number of venipunctures) and the operator's experience using a univariate +/- multivariate analysis. MEASUREMENTS AND MAIN RESULTS: Five hundred sixty-two SVCs (79.5%) were achieved without adverse events. Among the remaining 145 catheterizations, 67 (9.5%) failures, 55 (7.8%) arterial punctures, 22 (3.1%) pneumothoraces and 30 (4.2%) misplacements of the catheter tip occurred. More than one venipuncture was the only risk factor of failed catheterization [2 venipunctures, odds ratio =7.4 (2.1-26); >2 venipunctures, odds ratio =49.1 (16.8-144.1)]. More than one venipuncture and age 77 years or more were predictive of the occurrence of immediate complications [2 venipunctures, odds ratio =3.6 (1.8-7.0); >2 venipunctures, odds ratio =14 (7.7-25.3); age >or=77, odds ratio =1.8 (1.0-3.1)]. The operator's training was not predictive of failed catheterization or immediate complication. CONCLUSION: For SVC, more than one venipuncture is predictive of failed catheterization and immediate complication. Age 77 years or more was predictive of immediate complications.

Management of lower respiratory tract infections by French general practitioners: the AIR II study. Analyse Infections Respiratoires.

The Analyse Infections Respiratoires (AIR) II study is a prospective, multicentre survey of the management of lower respiratory tract infections in patients aged 15-65 yrs by general practitioners (GPs) in France. To obtain real-time data recording, practitioners were required to submit an anonymous copy of their drug prescriptions. They were then interviewed over the telephone about the patients' sociodemographic data, signs and symptoms, as well as their presumptive diagnosis and the investigations they had decided upon. GPs (n=3,144) reported 5,469 evaluable cases. Pneumonia accounted for 9.6% of diagnoses, acute exacerbations of chronic bronchitis 14.9% and acute bronchitis 72.5%. The symptomatology covered an extremely wide range of clinical features, which, although statistically different in terms of incidence, overlapped to a large extent across diagnoses. By contrast, hospitalization, investigations or referral to a specialist were much more prevalent in pneumonia, although still very infrequent in general terms (0.5, 1.2 and 10.8%, respectively). Antibiotics were prescribed in 96.5% of patients, with minor differences between diagnoses. However, other medications such as nonsteroid, anti-inflammatory drugs, steroids, nonspecific antitussives and bronchial liquefiers accounted for two-thirds of the prescriptions. This study demonstrates the lower respiratory tract infections encountered by general practitioners are usually mild. However, antibiotic prescription was more systematic than in previous studies and the prescription of nonspecific symptomatic treatments was twice as frequent. General practitioners did not perform additional examinations or refer on a regular basis. There was a high prescription rate for symptomatic treatment.

Insertion time of the pulmonary artery catheter in critically ill patients.

OBJECTIVES: Measurement of the time elapsed from the decision to use a pulmonary artery catheter to the onset of the adapted treatment. DESIGN: Prospective study. SETTING: Critical care unit of a university hospital. PATIENTS: A total of 104 critically ill patients. INTERVENTIONS: The time elapsed from the decision to use a pulmonary artery catheter to the onset of the adapted treatment. Five time intervals (availability, preparation, catheterization, data collection, and therapeutic intervals) were individualized according to the times of decision of pulmonary artery catheter insertion, operator's hand washing, venipuncture, postoperative dressing, data collection, and the effective onset of subsequent therapy. MEASUREMENTS AND MAIN RESULTS: Among 120 used pulmonary artery catheters, seven could not be inserted. The time to use the pulmonary artery catheter was never shorter than 45 mins (median value = 120 mins). For availability, preparation, catheterization, data collection, and therapeutic intervals, the median values were 30, 20, 20, 20, and 10 mins, respectively. The availability and data collection intervals were shortened during the night period and the fourth quarter of the study, respectively. CONCLUSIONS: The pulmonary artery catheter use is time consuming. However, the availability and data collection intervals could be shortened.

Evaluation in humans of the effects of radiocellular telephones on the circadian patterns of melatonin secretion, a chronobiological rhythm marker.

A decrease in melatonin secretion has been observed in small mammals under exposure to extremely low frequency electromagnetic fields. As there is some concern about possible health effects of the increasing use of radiocellular telephones emitting radiofrequency electromagnetic fields, we examined whether such fields would alter melatonin levels in the human. Volunteers were two groups totalling 38 men, 20-32 yr old. Exposures were to commercially available cellular telephones of the GSM 900 type (Global System for Mobile communication at 900 MHz) or DCS 1800 type (Digital Communication System at 1800 MHz), for 2 hr/day, 5 days/wk, for 4 wk, at their maximum power. Attention of the volunteers was sustained by TV projection of movies. Blood samples were collected hourly during the night and every 3 hr in the daytime. Four sampling sessions were performed at 15-day intervals: before the beginning of the exposure period, at the middle and the end of the exposure period, and 15 days later to evaluate the persistence or late appearance of potential effects. Evaluated parameters were the maximum serum concentration, the time of this maximum, and the area under the curve of the hormone profile. Melatonin circadian profile was not disrupted in 37 young male volunteers submitted to a typical pattern of exposure to the electromagnetic fields generated by two common types of cell phones.

The effects of cervical epidural anesthesia with bupivacaine on pulmonary function in conscious patients.

UNLABELLED: Cervical epidural anesthesia (CEA) can affect diaphragmatic function. We investigated the effects of CEA on the diaphragm muscle performance, breathing pattern, and respiratory drive of 10 healthy patients undergoing hand surgery before and after the administration of 0.25% and 0.375% bupivacaine. The lung volumes and flows, respiratory rate (RR), minute ventilation, respiratory cycle time, occlusion pressure, maximal inspiratory pressure (MIP), and hand grip strength were determined. ETCO2 and SpO2 were continuously monitored. The diaphragmatic excursion was evaluated using ultrasonography. Although CEA allowed painless hand rehabilitation, both 0.25% and 0.375% bupivacaine impaired diaphragmatic excursion, with values decreasing from 5.6 to 4.4 and 3.3 cm (P < 0.05), respectively, during forced sniff maneuvers. In the 0.25% and 0.375% bupivacaine groups, the values of MIP decreased from 74 to 56 and 44 cm H2O, forced vital capacity decreased from 3.8 to 3.2 and 2.8 L, and hand grip strength decreased from 43.3 to 27.8 and 20.5 kg force, respectively (P < 0.05). The tidal volume decreased from 0.8 to 0.6 and 0.5 L in the 0.25% and 0.375% bupivacaine groups, respectively, the RR increased from 14 to 18 breaths/min in both groups, and the occlusion pressure increased from 1.5 to 2.1 and 2.9 cm H2O in the 0.25% and 0.375% bupivacaine groups, respectively (P < 0.05). ETCO2 increased from 35.2 to 38.1 and 39.3 mm Hg in the 0.25% and 0.375% bupivacaine groups, respectively, and SpO2 decreased by 2% +/- 1% in the 0.375% bupivacaine group. CEA affects diaphragmatic function and the resulting lung volumes and MIP values. The observed alterations in breathing pattern and the significant increase in ventilatory drive may be caused by changes in the diaphragmatic muscle tension and an augmented CO2 load. In conclusion, we do not recommend this technique for routine postoperative hand rehabilitation using the studied bupivacaine concentrations. IMPLICATIONS: We studied cervical epidural anesthesia in healthy patients undergoing hand surgery. The technique allowed painless rehabilitation but affected breathing pattern, diaphragmatic function, and respiratory drive. We cannot recommend this technique for routine clinical use.

Pulsed Doppler ultrasonography guidance for catheterization of the subclavian vein: a randomized study.

BACKGROUND: Catheterization of the subclavian vein may lead to severe complications. The current randomized study compared a technique of pulsed Doppler ultrasonography guidance and the standard method for subclavian vein catheterization. METHODS: Standard and Doppler ultrasonography guidance methods were performed by the same physician in 286 patients, 143 in each group. Primary end points were immediate complications (arterial puncture, pneumothorax, wrong position of catheter tip), failures, the number of subclavian vein catheterizations with immediate complication or failure, the number of skin punctures per catheterization, and the time to placement of the guide wire. The secondary end points were the determination of predicting factors of successful cannulation in each group. RESULTS: Both groups were similar according to morphologic parameters of the patients. A greater number of subclavian vein catheterizations were performed on the right side using Doppler guidance (105 vs. 73, P < 0.01). Doppler guidance decreased complications (5.6% vs. 16.8%, P < 0.01), largely because of a smaller number of catheters for which the tip was defined to be in incorrect position (0.7% vs. 7.7%, P < 0.01). The time to catheterization was longer with Doppler guidance (300 vs. 27 s, P < 0.001). Failures, catheterizations of the subclavian vein with immediate complications or failure, and the total number of skin punctures per catheterization were similar in both groups. Using Doppler guidance, the presence of a good Doppler signal (124 of 143) was predictive of successful catheterization (123 successful cannulations, P < 0.001). CONCLUSIONS: Doppler guidance reduces the incidence of inappropriately positioned subclavian catheters.

Changes in breathing pattern and respiratory muscle performance parameters during difficult weaning.

OBJECTIVE: This study examined, using noninvasive means, the changes in breathing pattern and inspiratory muscle pressure-time indices during difficult progressive withdrawal of pressure-support ventilation. DESIGN: A prospective analysis of the temporal evolution of several respiratory variables in difficult-to-wean patients. SETTING: A university hospital intensive care unit. PATIENTS: A heterogeneous group of 17 patients receiving prolonged mechanical ventilation. INTERVENTIONS: Daily measurements of breathing pattern and respiratory muscle performance parameters in difficult-to-wean patients. MEASUREMENTS AND MAIN RESULTS: We examined breathing pattern variables, rapid shallow breathing (respiratory rate/tidal volume), tracheal occlusion pressure, maximal inspiratory pressure (P(I)max), and the tension-time index of the inspiratory muscles (TTmus = P(I)/P(I)max x Ti/Ttot) (where Ti/Ttot is inspiratory fraction of the cycle). All measurements were repeated at 24-hr intervals throughout the difficult weaning period. The patients were extubated on satisfying ten of 12 classical weaning criteria. Eleven patients were successfully weaned from mechanical ventilation while six patients were not. Weaning failure was associated with the following: a) longer periods of mechanical ventilation before weaning; b) high values of tracheal occlusion pressure, respiratory rate, minute ventilation, and effective impedance maintained throughout the difficult weaning period; and c) persistent high PaCO2 and intrinsic positive end-expiratory pressure values. As the weaning failure patients' inspiratory muscles confronted an increasing inspiratory load, values of the tension-time index of the inspiratory muscles entered or remained in the fatigue zone. In contrast, weaning success patients normalized their breathing pattern and decreased their tracheal occlusion pressure, effective impedance, and tension-time index values. CONCLUSIONS: Breathing pattern alterations and respiratory muscle performance impairments lead to ventilator dependency after prolonged mechanical ventilation. The measurement of variables such as the noninvasive tracheal occlusion pressure, inspiratory power of breathing, and tension-time index of the inspiratory muscles facilitate the management of difficult-to-wean patients.

Sacral reflex latency correlated by age and sex.

This prospective study was undertaken on 190 subjects who had no prior central or peripheral nerve supply pathology and where the value of the sacral reflex latency was compared by age and sex in order to determine precise norms. There were 90 men whose age averaged 56.9 +/- 13 years and 100 women with an average age of 54 +/- 13.1. The reflex was obtained by stimulating the dorsal nerve of the penis and the clitoris and taking a reading in the intermediate part of the external anal sphincter muscle. An averaging technique was used (over 30 stimulation occurrences). The average intensity of the stimulation was 15 mA. The value of the stimulus reaction latency taken at the positive peak was analyzed statistically. The average value was 37.6 +/- 5.36 ms in male subjects and 46.6 +/- 8.08 in female subjects. In men, values varied from 36.6 +/- 4.26 ms at under 35 years of age and reached 42 +/- 3.52 ms at over 75 years. In women, values varied from 37.33 +/- 7.69 ms at under 35 years to 55.6 +/- 4.39 ms at over 75 years of age. In a previous article we discussed ageing features in nerves and muscles. These features are largely responsible for the occurrence of static pelvic problems. The purpose of this study is to compare the sacral reflex latency by sex and age in normal subjects.

Pudendal nerve motor latency correlation by age and sex.

This study was a prospective study, it was undertaken on 172 subjects who had no prior central or peripheral nerve supply pathology and who had not an antecedent of anal surgery. The subjects had a normal value of the sacral reflex latency to be included in this study. In this population the value of the pudendal motor nerve latency was compared by age and sex in order to determine precise norms. There was 92 men whose age adveraged 36 +/- 14.57 years and 80 women with an average age of 55.03 +/- 15.7. The motor latency was obtained by stimulating the nerve by rectal or vaginal tuch-near the sciatic spine with a St Mark's electrod and taking a reading in the intemediate part of the external anal sphincter muscle. The intensity of the stimulation was 70 to 80 mA. The stimulation and the recording was repeteded five both on each side and the shorter latency whose choised. The value of the motor latency taken at the positive peak was analysed statiscally. The average value was 5.52 +/- 1.9 ms on right pudendal nerve and 5.74 +/- 1.6 ms on the left in male subjects and 6.16 +/- 1.8 in the right pudendal nerve and 6.42 +/- 1.96 on the left in female subjects. The values on right pudendal nerve latency varied from 4.9 +/- 1.28 ms in men and 4.76 +/- 1.6 ms. in women at under 28 years and to 5.06 +/- 2.06 ms in men and 7.7 +/- 1.8 ms in women at over 70 years. The values on the left side varied from 5.53 +/- 1.5 ms in men and 4.78 +/- 1.35 ms in women at under 28 years and to 5.06 +/- 2.06 ms in men and 8.47 +/- 1.95 ms in women at over 70 years. In men population, the value of the motor latency of the pudendal nerve is not correlated with age. In women population, the value is correlated with age.

Plasma amino acid concentrations in elderly patients with protein energy malnutrition.

OBJECTIVE: to compare amino acid concentrations in healthy and malnourished elderly patients. METHOD: plasma amino acid concentrations were examined in 24 men and women (80-100 years of age) with protein energy malnutrition (PEM) and compared with those of 44 healthy, similarly-aged controls. Plasma samples were determined by using cation exchange columns with ninhydrin detection in an high performance liquid chromatography system. RESULTS: essential amino acid and non-essential amino acid plasma concentrations were significantly decreased in PEM (0.01 < P < 0.0001). Branched-chain amino acids and urea cycle amino acid plasma concentrations fell significantly (P < 0.0001). Plasma concentrations of alanine and glutamic acid + glutamine were also significantly reduced (P < 0.0001). CONCLUSIONS: in underweight elderly patients, the plasma amino acid pattern reflects the severity of the metabolic disturbance.

Effects of ketamine on ventricular conduction, refractoriness, and wavelength: potential antiarrhythmic effects: a high-resolution epicardial mapping in rabbit hearts.

BACKGROUND: The aims of the study were to verify the effects of ketamine on ventricular conduction velocity and on the ventricular effective refractory period, to determine its effects on anisotropy and on homogeneity of refractoriness, and to use wavelength to determine whether ketamine has antiarrhythmic or arrhythmogenic properties. METHODS: A high-resolution epicardial mapping system was used to study the effects of 50, 100, 150, and 200 microM racemic ketamine in 15 isolated, Langendorff-perfused rabbit hearts. Five hearts were kept intact to study the effects of ketamine on spontaneous sinus cycle length (RR) interval and its putative arrhythmogenic effects. In 10 other hearts, a thin epicardial layer was obtained by an endocardial cryoprocedure (frozen hearts) to study ventricular conduction velocity, ventricular effective refractory periods (five sites), and ventricular wavelength. RESULTS: Ketamine induced a concentration-dependent lengthening of the RR interval. Ketamine slowed longitudinal and transverse ventricular conduction velocity with no anisotropic change, and it prolonged the ventricular effective refractory period with no significant increase in dispersion. Ventricular longitudinal and transverse wavelengths tend to increase, but this was not statistically significant. Finally, no arrhythmia could be induced regardless of the ketamine concentration. CONCLUSION: Ketamine slowed ventricular conduction and prolonged refractoriness without changing anisotropy or increasing dispersion of refractoriness. Although these effects should result in significant antiarrhythmic effects of ketamine, this should not be construed to suggest a protective effect in ischemic or other abnormal myocardium.

Electrophysiologic and proarrhythmogenic effects of therapeutic and toxic doses of imipramine: a study with high resolution ventricular epicardial mapping in rabbit hearts.

Electrophysiologic and proarrhythmogenic effects of imipramine were studied by use of 21 Langendorff-perfused rabbit hearts and high-resolution mapping to analyze epicardial activation of the left ventricle. In 16 hearts, a thin layer of epicardium was obtained by an endocardial cryotechnique (frozen hearts). Five hearts were kept intact (nonfrozen imipramine-treated group). Preparation stability was verified in six frozen hearts. In 10 frozen and in 5 nonfrozen hearts, 0.01, 0.1, 1.0, 2.0 and 5.0 micrograms/ml imipramine were administered. In nonfrozen imipramine-treated hearts, imipramine induced bradycardia at 5.0 micrograms/ml (291.8 +/- 40.5 vs. 495.2 +/- 54.4 msec, P = .02), one A-V block at 5.0 micrograms/ml and two monomorphic ventricular tachycardias (MVT) at 2.0 and 5.0 micrograms/ml. In 4/10 frozen hearts, three MVT were induced at 1.0 microgram/ml imipramine and one MVT at 2.0 micrograms/ml imipramine. All MVT were based on reentry around a line of functional conduction blocks. Imipramine (2.0 micrograms/ml) slowed longitudinal and transversal ventricular conduction velocities at a pacing cycle length of 1000 msec from 71.7 +/- 6.1 to 63.0 +/- 7.7 cm/sec (P = .008) and from 32.9 +/- 2.6 to 27.7 +/- 2.8 cm/sec (P = .009), respectively, and prolonged ventricular effective refractory period from 141.9 +/- 9.3 to 279.1 +/- 112.6 msec (P = .03). Imipramine induced dose- and use-dependent slowing of ventricular conduction velocity facilitating functional conduction blocks and reentrant MVT.

Cardiac output measurement in critically ill patients: comparison of continuous and conventional thermodilution techniques.

The purpose of the study was to compare cardiac output (CO) measurement by continuous (CTD) with that by conventional thermodilution (TD) in critically ill patients. In 19 of 20 critically ill patients requiring a pulmonary artery catheterism, 105 paired CO measurements were performed by both CTD and TD. Regression analysis showed that: CTD CO = 1.18 TD CO - 0.47. Correlation coefficient was 0.96. Bias and limit of agreement were -0.8 and 2.4 L.min-1, respectively. When a Bland and Altman diagram was constructed according to cardiac index ranges, biases were -0.2 and -0.3 and -0.8 L.min-1.m-2 and limits of agreement were 0.3, 0.7 and 1.6 L.min-1.m-2 for low (< 2.5 L.min-1.m-2), normal (between 2.5 and 4.5 L.min-1.m-2) and high (> 4.5 L.min-1.m-2) cardiac indexes, respectively. It is concluded that CTD, compared with TD, is a reliable method of measuring CO, especially when cardiac index is < or = 4.5 L.min-1.m-2.

An enzymatic method for assaying sulbactam in human serum: comparison with high performance liquid chromatography.

An enzymatic method using nitrocefin as substrate was developed to assay sulbactam in human serum. Serum containing sulbactam was incubated with purified titrated TEM-1 beta-lactamase and nitrocefin was then added to the mixture to determine the remaining beta-lactamase activity and consequently the concentration of sulbactam. Assays were carried out on five patients with pulmonary infections receiving sulbactam plus amoxycillin iv. The values for serum sulbactam concentrations determined by the enzymatic method were compared with those determined by high performance liquid chromatography (HPLC). The correlation coefficient was 0.990 for serum sulbactam concentrations below 15 mg/L.

[Effect of the age and the sex on plasma concentration of amino acids].

The effects of age and sex on the plasma free amino acid pattern of healthy men and women aged from 80 to 100 years were compared with those in younger adults (20 to 45 years old). Plasma amino acid concentrations were determined by ion-exchange chromatography on a 6300 Beckman analyzer. The plasma concentrations of valine, leucine, isoleucine, proline, glutamine + glutamic acid and phenylalanine were higher in males than in females. Citrulline, half-cystine, histidine, glutamine+glutamic acid, lysine, ornithine and phenylalanine plasma concentrations and the total plasma amino acids were higher in elderly than in younger subjects.

[Trans-scleral cyclo-photocoagulation. Results over 6 months].

Transscleral contact cyclophotocoagulation with ND YAG Laser continuous mode permits the induction of a focused ciliary process with a secretory surface decrease. This treatment has been used for the treatment of refractory glaucoma since 1987. We report the treatment by transscleral cyclophotocoagulation of 49 patients with terminal glaucoma. All 49 patients had a measurable visual acuity and an elevated intraocular pressure under maximal medical treatment. None could be operated by trabeculectomy. The origin of the glaucoma was neovascular (26 patients), open angle glaucoma (9 patients) secondary glaucoma (14 patients). 62.2% of the patients had an intraocular pressure < or = 25 mm after 6 months; 8% showed decrease visual acuity. We describe the complications of the treatment and compare the efficacy of treatment depending on the origin of the glaucoma: neovascular or not.

Pharmacodynamics of vecuronium in patients with and without renal failure: a meta-analysis.

Eight trials comparing the effects of vecuronium in patients with either normal renal function or renal failure were subjected to a meta-analysis. Vecuronium doses were similar in the different trials, identical in the two patient groups of any given trial, and ranged from 0.05 to 0.14 mg.kg-1. Neuromuscular blockade was assessed by TOF or single twitch stimulation, and recorded by either mechanomyography or electromyography. Indices of blockade included onset time (from injection to maximal twitch depression), duration of action (from injection to recovery to 25% of control twitch) and 25-75% recovery index. Statistical analysis used Hedges method: effect size and variance were calculated for each relevant outcome, then the global effect size was estimated by pooling the effect sizes of each trial. Three separate meta-analyses were conducted. No differences were found either in onset time, or in recovery index between the two groups, whereas the duration of action was longer in the renal failure group. It is concluded that renal function is likely involved in the pharmacokinetic parameters of vecuronium.

Antibiotic prophylaxis against postpartum endometritis after vaginal delivery: a prospective randomized comparison between Amox-CA (Augmentin) and abstention.

The most common adverse outcome associated with vaginal delivery is endometritis. It plays a significant role in postpartum morbidity and mortality. There is considerable evidence to support the idea that a single dose of antibiotic after vaginal delivery might decrease the incidence of postpartum endometritis. In this study the evaluation of the efficacy of antibiotic prophylaxis was based upon comparison of a group of patients given a single dose of Amox-CA (Augmentin) with a group of patients without treatment. The study was performed in the Department of Obstetrics and Gynecology of the A. Béclère Public Hospital, Clamart, France (Paris-Sud University). The patients who were the subject of the study had delivered vaginally during the period of 1 year, and were free of any clinical diagnosis of chorioamnionitis or other extragenital infection, had a maternal temperature of less than 38 degrees C during labor and 1 h after delivery, and had no history of allergy to penicillins or cephalosporins. After application of exclusion criteria, 1373 patients were randomized and 1291 included 610 in Group I given Amox-CA and 681 in Group II without any antibiotic. A single dose of 1.2 g of Amox-CA was given by intravenous injection, 1 h after delivery, in Group I. Patients of Group II received no injection. Postpartum status was evaluated before the patient left hospital and 2 weeks later. The two groups were similar in terms of demographic and clinical parameters. Four patients developed endometritis in Group I (4/610, 0.66%). Sixteen patients in Group II developed endometritis (16/680, 2.38%) (P = 0.013; 95% confidence interval (CI), 0.36-3.08%).(ABSTRACT TRUNCATED AT 250 WORDS)
