The dorsal scapular nerve, a proximal branch of the brachial plexus, may be imaged using ultrasound. This nerve supplies the rhomboid and levator scapulae muscles while providing significant sensory innervation to the scapula. An ultrasound-guided nerve block of the dorsal scapular nerve provided analgesia after surgery of the scapula. Selective blockade of this nerve, without blocking the remainder of the brachial plexus, results in specific analgesia of the scapula, sparing sensory and motor function of the ipsilateral arm.

To determine whether the previously published relationship between anesthetic technique and rate of surgical site infections (SSIs) was influenced by institution specific effects. ⋯ The impact of anesthetic technique on SSI following hip and knee replacement surgery may be site specific and using locally gathered quality data may assist in assessing specific institutional impact.

A case in which the intraoperative administration of propofol was strongly associated with an acute episode of diabetes insipidus is presented.

Randomized Controlled Trial
Prewarming of the i-gel facilitates successful insertion and ventilation efficacy with muscle relaxation: a randomized study.
To determine if prewarming of the i-gel (Intersurgical, Wokingham, United Kingdom) improves insertion and ventilation efficacy with muscle relaxation in patients undergoing elective surgery. ⋯ Prewarming the i-gel to 42°C demonstrated a higher successful ventilation initiation.

To determine the relationship between preoperative catecholamine levels and intraoperative peak plasma lactate levels in patients who underwent adrenalectomy for pheochromocytoma. ⋯ Catecholamine release caused by surgical manipulation may be a possible cause of intraoperative transient lactic acidosis, and it should be considered as a differential diagnosis of intraoperative lactic acidosis. Intraoperative peak plasma lactate level was correlated with preoperative epinephrine-releasing activity.
