ReviewNew insulin analogues and perioperative care of patients with type 1 diabetes.
While insulin remains the mainstay of managing type 1 diabetes, much has changed over the last 15 years. These changes should help in managing patients with type 1 diabetes during the perioperative period. More flexible insulin therapy has three components: (1) basal, (2) prandial and (3) corrective. ⋯ We suggest that for many procedures, patients' usual regimens can be maintained in the perioperative period, providing less disruption and, possibly, greater safety. Both hyperglycaemia and hypoglycaemia reflect poor management: we suggest a target glucose range of 5 to 10 mmol/l. The importance of frequently measuring blood glucose and appropriate responses cannot be overemphasised.

ReviewRegional anaesthesia for bilateral upper limb surgery: a review of challenges and solutions.
Regional anaesthesia for bilateral upper limb surgery can be challenging, yet surgeons are becoming increasingly interested in performing bilateral procedures at the same operation. Anaesthetists have traditionally avoided bilateral brachial plexus block due to concerns about local anaesthetic toxicity, phrenic nerve block and pneumothorax. We discuss these three concerns and review whether advances in ultrasound guidance and nerve catheter techniques should make us reconsider our options. ⋯ Since phrenic nerve block remains an issue even with low doses of local anaesthesia, bilateral interscalene blocks are still not recommended. Peripheral nerve blocks have excellent safety profiles and are ideal for ultrasound guidance. Regional anaesthesia can be a suitable option for bilateral upper limb surgery.
