Preoperative procedures


Local anaesthesia may be used for shoulder arthroscopy and Warren et al[8] have reported a series of 44 arthroscopic subacromial decom­pressions performed under scalene block with­out anaesthetic problems. However, general anaesthesia for shoulder arthroscopy is prefer­able. General anaesthesia prevents embar­rassment to the surgeon and loss of faith by the patient during the learning curve of the proce­dure, when the surgeon's dexterity may not match the patient's expectations! It is essential that the patient is intubated in order to remove both the anaesthetist and the anaesthetic equipment from the operative field, and to allow the surgeon to reach across the patient's head. The patient should be adequately monitored and all pressure areas should be properly padded.

When the lateral decubitus position is used, an axillary roll should be placed under the patient in order to prevent undue strain being placed on the brachial plexus of the unoper-ated side (Figure 4.10).
