Time at the surgical ‘coal-face’ has been reduced by introduction of the European Working Time Directive (EWTD) significantly impacting training opportunity. Our null hypothesis was that duration of surgery is significantly longer if a trainee were performing the operation despite supervision or level of trainee experience. Cemented hip hemiarthroplasty was chosen as our index procedure as complexity is largely comparable between cases. 461 patients were identified on the hospital trauma database. Data were augmented by information regarding level of surgeon, assistant and time of surgery from the hospital theatre database. There was no significant difference in registrar and consultant operative times, mean time 69 and 72 minutes respectively. SHOs were significantly slower (mean 80 minutes, p=0.0006). Junior (ST5 or less) registrars were significantly slower (mean 81minutes, p=0.0002) whereas senior registrars were not. Supervision level had no effect on duration of senior registrar operations but when junior registrars were consultant supervised they were not significantly slower (mean 75 minutes, p=0.09). Supervised operating therefore reduces time variability and should be promoted within a climate of training. Increase in mean operative time in registrars and SHOs is insignificant within a day's operating and is unlikely to lead to cancellations of cases.
Early detection of Developmental Dysplasia of the Hip (DDH), and treatment, may prevent the need for surgical correction following late presentation. Neonatal examination, and ultrasound screening of at risk groups, does not detect all cases. Most neonates treated in the Intensive Care Unit (NICU) have abdominal radiographs performed during their stay. These include the hips but DDH is not routinely looked for. 50 neonatal abdominal films (five from patients who subsequently were found to have DDH, 45 from patients without this condition) were randomly shown to three paediatric orthopaedic surgeons and three paediatric radiologists on two separate occasions. Each was asked whether they would refer the patient for further investigation. An overall sensitivity of 25.5% (Range 0–60%) and specificity of 93.2% (Range 87–97%) was found with a positive predictive value (PPV) of 14.0% (Range 0–37%) and negative predictive value (NPV)of 96.3% (Range 95–98%). Although the low sensitivity and PPV make interpretation of these films a poor way to diagnose DDH, the high specificity and NPV suggest that they may be used as a prompt to further investigation. Therefore, we propose that DDH should be looked for on these films and, where there is radiological suspicion, ultrasound examination should be advised.
We carried out a comparison of the analgesic requirements, length of stay in hospital, complications and cost effectiveness of patients who had either a continuous disposable infusion pump or standard treatment for unicompartmental knee replacement. This study began as an audit. We completed the audit loop with a prospective study after implementing our recommendations. The device is a single use disposable elastometric pump, set immediately after surgery to deliver a continuous flow of 0.5% bupivacaine at a rate of 2mls per hour for 48 hrs into the knee joint via a fine catheter with a fenestrated tip. The case notes of all patients in the study were analysed to establish their total analgesic requirements for 48hrs following surgery. Complications and length of stay in hospital were recorded This has changed our clinical practice. Results of our study of 50 patients, 25 in each group (age and sex matched) confirmed that there was a significant reduction in opiate requirements after introduction of the pain pump. Length of stay in hospital was reduced from 5.7 to 3.9 days. Patients' requirements for NSAIDs were reduced. There were no significant complications in the pain pump group. The costs of the pump (£40) were offset by the reduction in analgesic requirements and shortened length of stay in hospital. We conclude this form of analgesia is safe, effective and cost effective. Our department has now changed to using the pump for all unicompartmental knee replacements.
