Randomized Controlled Trial Comparative Study
Comparison of sevoflurane volatile induction/maintenance anaesthesia and propofol-remifentanil total intravenous anaesthesia for rigid bronchoscopy under spontaneous breathing for tracheal/bronchial foreign body removal in children.
Foreign body aspiration is a life-threatening condition, with children under 3 years of age most at risk. This study was designed to compare the clinical characteristics of sevoflurane volatile induction/maintenance anaesthesia (VIMA) and propofol-remifentanil total intravenous anaesthesia (TIVA) for children undergoing rigid bronchoscopy under spontaneous breathing for tracheal/bronchial foreign body removal. ⋯ Compared with propofol-remifentanil TIVA, sevoflurane VIMA provides more stable haemodynamics and respiration, faster induction and recovery and higher incidence of excitement in paediatric patients undergoing tracheal/bronchial foreign body removal under spontaneous breathing.

Randomized Controlled Trial Comparative Study
Postoperative efficacies of femoral nerve catheters sited using ultrasound combined with neurostimulation compared with neurostimulation alone for total knee arthroplasty.
Neurostimulation is commonly used to perform femoral nerve block. Ultrasound can be used to identify nerve structures and guide needle placement. The aim of this study was to compare postoperative analgesic efficiency when femoral nerve catheters were sited using ultrasound (in-plane approach) combined with neurostimulation or neurostimulation alone, for total knee arthroplasty. ⋯ Continuous perineural femoral catheter placement using ultrasound combined with neurostimulation and an in-plane approach reduces total doses of local anaesthetic, morphine consumption and improves postoperative pain management by comparison with neurostimulation alone.

Difficult tracheal intubation following induction of general anaesthesia for caesarean section is a cause of morbidity and mortality. Our aim was to evaluate five bedside predictors that might identify women with potential intubation difficulty immediately prior to emergency caesarean section. ⋯ Airway assessment using these tests cannot be relied upon to predict a difficult intubation at emergency caesarean section as the low sensitivity means that 79% (95%CI 49-95) of difficult intubations will be missed.
