Randomized Controlled Trial
Positive end-expiratory pressure during laparoscopy: cardiac and respiratory effects.
To determine the effect of positive end-expiratory pressure (PEEP) on the respiratory system and on cardiac function. ⋯ Ventilation with PEEP (up to 10 cm H2O) recruits the hypoventilated areas of the lungs and reduces cardiac afterload.

Observational Study
Effects of surgery, general anesthesia, and perioperative epidural analgesia on the immune function of patients with non-small cell lung cancer.
To assess preoperative and postoperative immune function in patients undergoing surgical resection of non-small cell lung cancer during general anesthesia and postoperative epidural analgesia. ⋯ Innate immunity is depressed in patients with non-small cell lung cancer after surgical resection, and immunity is not preserved by the use of postoperative epidural analgesia.

Supraclavicular brachial plexus block is commonly used for upper extremity surgery. Respiratory arrest in three patients with end-stage renal disease after ultrasound-guided supraclavicular brachial plexus block for creation of an arteriovenous graft over a 6-month period is presented. Patients with renal failure may represent a group at particular risk for respiratory failure following supraclavicular brachial plexus block.
