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.

Review Meta Analysis
Postoperative complications in patients with obstructive sleep apnea: a meta-analysis.
To determine whether a diagnosis of obstructive sleep apnea (OSA) imparts an increased risk of postoperative respiratory failure, cardiac events, and intensive care unit (ICU) transfer than patients with no OSA diagnosis. ⋯ Surgical patients with OSA are at increased risk of postoperative respiratory failure, cardiac events, and ICU transfer.

Randomized Controlled Trial Comparative Study
The effects of propofol-midazolam-ketamine co-induction on hemodynamic changes and catecholamine response.
To compare the clinical efficacy of co-induction with propofol-midazolam-ketamine with etomidate as the sole induction agent. ⋯ The higher norepinephrine/epinephrine ratio noted in the single-drug group may be implicated in lower adrenal sympathetic activity. Propofol-midazolam-ketamine co-induction may be used instead of etomidate for anesthesia induction in patients with hemodynamic instability.

To validate intraoperative pulse hemoglobin (SpHb) measurements in anesthetized patients with large forearm temperature - fingertip temperature gradients. ⋯ SpHb measured at fingertip was significantly affected by the perfusion state, with lower perfusion associated with lower SpHb. Thermoregulatory vasoconstriction affects measurement of SpHb.
