Difficult and failed intubation in obstetric anaesthesia: an observational study of airway management and complications associated with general anaesthesia for caesarean section.
Recent developments in anaesthesia and patient demographics have potentially changed the practice of obstetric general anaesthesia. There are few contemporary data on Australasian practice of general anaesthesia for caesarean section, especially relating to airway management, anaesthetic techniques and complications. ⋯ General anaesthesia is most commonly used in emergency situations. Tracheal intubation after rapid-sequence induction remains the predominant approach to airway management in Australasia. The incidence of failed intubation is consistent with previous studies. Aspiration prophylaxis is not routinely used for emergency surgery.

Randomized Controlled Trial Comparative StudyImpact of the addition of sufentanil 5 microg or clonidine 75 microg on the minimum local analgesic concentration of ropivacaine for epidural analgesia in labour: a randomized comparison.
Addition of lipophilic opioids or alpha2-agonists to local anaesthetic solutions reduces local anaesthetic requirements and side effects. While the efficacy and side effects of these adjuvants are dose-related, information about their relative analgesic potencies is lacking, making it difficult to draw meaningful clinical conclusions. The aim of the present study was to assess the relative sparing of ropivacaine by clinically relevant doses of sufentanil and clonidine using the minimum local analgesic concentration (MLAC) model. ⋯ Sufentanil 5 microg and clonidine 75 microg produce similar reductions in the MLAC of ropivacaine. This finding will make feasible the assessment of the side effects of these adjuvants administered at equipotent doses in further studies.

Case Reports Multicenter StudyA prospective study of awareness and recall associated with general anaesthesia for caesarean section.
The obstetric population is considered at high risk of awareness and recall when undergoing general anaesthesia for caesarean section. In recent years the incidence may have been altered by developments in obstetric anaesthesia. ⋯ Awareness with recall of intraoperative events remains a significant complication of obstetric general anaesthesia but was potentially avoidable in all cases detected in this study.
