The majority of upper extremity surgeries are performed on an ambulatory basis under intravenous regional anaesthesia or brachial plexus blockade. The former technique is easy to perform, has a rapid onset and a high success rate but provides limited post-operative analgesia. Brachial plexus blockade provides excellent intraoperative anaesthesia as well as post-operative analgesia, eliminates the need for post-operative opioids, resulting in a decrease in recovery time, shortened hospital stay, increased patient satisfaction and ultimately a decrease in perioperative costs when compared with general anaesthesia. This chapter reviews upper extremity surgical procedures performed below the shoulder, the anaesthetic options available, and techniques used to optimize post-operative pain control.

Technological advances in imaging, computing and surgical instrumentation have encouraged the application of minimally invasive surgical techniques to various neurosurgical disorders. This chapter discusses the wide application of neurosurgery and the implications for anaesthesia, focusing on the specific anaesthetic considerations for neuroendoscopy, stereotactic procedures and radiosurgery.

ReviewAnaesthetic considerations for laparoscopic cholecystectomy.
Minimally invasive surgical procedures aim to minimize the trauma of the interventional process but still achieve a satisfactory therapeutic result. Tissue trauma is significantly less than that with conventional open procedures, offering the advantages of reduced post-operative pain, shorter hospital stay, more rapid return to normal activities and significant cost savings. Laparoscopic cholecystectomy is now a routinely performed procedure and has replaced conventional open cholecystectomy as the procedure of choice for symptomatic cholelithiasis. ⋯ Intra-operative complications may include traumatic injuries associated with blind trocar insertion, gas embolism, pneumothorax and surgical emphysema associated with extraperitoneal insufflation. Appropriate monitoring and a high index of suspicion can result in early diagnosis of, and treatment of, complications. Laparoscopic cholecystectomy has proven to be a major advance in the treatment of patients with symptomatic gallbladder disease.

The surgical requirement for thoracoscopy is a good view of the contents of the thorax. This is achieved by capitalizing on natural consequences and the skills of anaesthesiologists to produce a pneumothorax and collapse the ipsilateral lung--a process that is commonly enhanced by insufflating carbon dioxide. Insufflating CO2 to actively promote lung collapse creates the dynamics of a tension pneumothorax. ⋯ The mechanism is not defined but it differs from that associated with thoracotomy. Epidural analgesia and opioids may be required. Chronic pain syndromes have been described as complications.

ReviewAnaesthesia for minimally invasive surgery in children.
There continues to be an increase in the applications of minimally invasive surgical techniques in infants and children. This increase includes their use for new surgical procedures as well as their application in younger patients including neonates. As with any new surgical procedure, specific modifications of the anaesthetic technique may be necessary. This chapter reviews (1) the pre-operative evaluation of infants and children scheduled for minimally invasive surgery; (2) techniques for pre-medication and anaesthetic induction; (3) intra-operative anaesthetic implications of laparoscopy, including the cardiorespiratory consequences of CO2 pneumoperitoneum; (4) intra-operative anaesthetic implications of thoracoscopy, including techniques for one-lung ventilation (OLV); and (5) post-operative issues, including pain management and monitoring of cardiorespiratory function as they apply to the patient of paediatric age.
