Postal survey of cuffed or uncuffed tracheal tubes used for paediatric tracheal intubation.

A postal survey of the use of cuffed or uncuffed tracheal tubes for tracheal intubation in children and infants was performed to investigate the criteria used for deciding the choice of tube and the manner of inflating the cuff in the case of use of a cuffed tracheal tube (CTT). From 200 questionnaires despatched, replies were received from 130 paediatric anaesthesiologists (response rate 65%). In paediatric practice, the CTT was routinely used by 25% of respondents for more than 80% of their patients, while more than 37% of respondents use them in less than 20% of the cases. The three main criteria used for inflating a cuff were: (i) the presence of a leak, (ii) the type of surgery associated with the presence of a leak and (iii) the patient's age associated with the type of surgery and the presence of a leak. These criteria were specified, respectively, by 32%, 24% and 18% of the respondents. The cuff was inflated in response to a leak in 18% of the cases and as a response to a pressure manometer in 15% of the cases. Few paediatric anaesthesiologists use a cuffed tracheal tube routinely for tracheal intubation in children, and fewer actually use a pressure monitoring device, while it is suggested that the cuff pressure should be monitored in case of CTT.

Behavioral interventions reduce infant distress at immunization.

OBJECTIVE: To assess the effectiveness of simple behavioral interventions at immunization on behavioral and biochemical indicators of distress in infants and parents in a primary care setting. DESIGN: Subjects were enrolled sequentially to control (standard care) and intervention groups. Intervention parents (n=57) were provided information about techniques to help their infants at immunization. Standard care parents (n=45) did not receive this information. Immunizations were videotaped and coded for infant and parent behaviors. Using a visual analog scale, parents rated their infant's and their own comfort at study enrollment, immediately after immunization, and at check-out. Saliva samples collected from infants and parents at study enrollment and at 15, 30, and 60 minutes after immunization were assayed for cortisol concentration by standard radioimmunoassay. Data were analyzed using chi2, analysis of variance, and general linear modeling. Patterns of salivary cortisol change after immunization were analyzed using hierarchical linear modeling. SETTING: A single, urban pediatric practice during 2 summers (1997 and 1998). SUBJECTS: Infants 2 to 24 months of age (n= 102) and their parents. MAIN OUTCOME MEASURES: Duration of infant distress (in seconds); parent use of behavioral intervention; infant and parent salivary cortisol concentrations (in nanomoles per liter). RESULTS: Intervention parents were more likely to use a behavioral technique with their infants before immunization (P<.05). Total infant distress was shorter for intervention infants at immunization (P<.01), and these infants were rated as more comfortable by their parents (P<.001) immediately after immunization. Salivary cortisol levels were lower for intervention infants at 15, 30, and 60 minutes after immunization (P<.05). CONCLUSION: Simple behavioral interventions before immunization are associated with reductions in behavioral and biochemical indicators of infant distress.

Double-blind randomized prospective study of the efficacy of antibiotic prophylaxis for open reduction and internal fixation of closed ankle fractures.

Antibioprophylaxis has been proven to be efficient for some orthopaedic procedures. However, its efficacy for clean limited procedures with metallic implants is not clear. One hundred twenty-two closed ankle fracture patients undergoing open reduction and internal fixation were randomized, double-blindly, to receive either cephalothin (1 g i.v. every 6 h x four doses) or a placebo starting before tourniquet application. Mean trauma-surgery delay was 30.2 h, and average tourniquet duration was 65.4 min. Four patients (three of 62 on placebo and one of 60 on cephalothin) developed a superficial wound infection. One of the patients in the placebo group was hospitalized and treated with i.v. antibiotics. However, there was no osteomyelitis or premature hardware removal. The difference between the two groups was not statistically significant (chi 2 test of appreciation p = 0.33, two-tailed probabilities). Therefore, cephalothin prophylaxis does not seem justified in this patient population. A larger series is needed to avoid a type II error.

Results of derotational humeral osteotomy in posterosuperior glenoid impingement.

We identified 20 throwing athletes who continued to have pain after articular debridement for posterosuperior impingement syndrome. These patients were unable to resume sports, and we subsequently performed a derotational humeral osteotomy with a myorraphy of the subscapularis muscle. Patients were observed for an average of 46 months (range, 12 to 69). Eleven patients were able to resume the same sport at the same level, five resumed the same sport at a lower level, three changed sport secondary to persistent pain, and the last patient did not resume any sport and was worse after surgery. Patients returned to sports at an average of 6 months postoperatively (range, 4 to 44) and to their previous level of sports at an average of 12 months (range, 8 to 18). The mean increase in humeral retroversion was 29 degrees (range, 18 degrees to 44 degrees) Three women with preoperative multidirectional hyperlaxity were considered to have failed results. Derotational humeral osteotomy can be considered in the throwing athlete with posterosuperior impingement after failure of all other means of treatment. Careful patient selection and preoperative evaluation of humeral retroversion is important. Best results can be achieved in a motivated patient with low retroversion (< 10 degrees). If retroversion is normal (20 degrees to 30 degrees), the surgical indication is unclear. We do not recommend this surgery for patients with hyperlaxity.
