Clinical TrialCompressing the non-dependent lung during one-lung ventilation improves arterial oxygenation, but impairs systemic oxygen delivery by decreasing cardiac output.
We have previously found that compression of the non-dependent lung improves arterial oxygenation during one-lung ventilation (OLV) in patients undergoing esophagectomy. The purpose of this study was to investigate the effects of compression of the non-dependent lung on hemodynamic indices and oxygen delivery using a minimally invasive cardiac output (CO) monitor. ⋯ Although non-dependent lung compression may be a potentially effective measure to treat hypoxemia during OLV, it should be noted that CO and systemic oxygen delivery may be decreased by this maneuver.

Randomized Controlled Trial Comparative StudyComparison of 0.25% levobupivacaine and 0.25% bupivacaine for posterior approach interscalene brachial plexus block.
This study compares the onset time and quality of posterior approach interscalene brachial plexus block produced by 0.25% levobupivacaine and 0.25% bupivacaine. ⋯ We conclude that 0.25% levobupivacaine and 0.25% bupivacaine have similar motor and sensory block onset times and qualities when used in posterior approach interscalene brachial plexus block, and provide comfortable anesthesia and analgesia for shoulder surgery.

Comparative Study Clinical TrialThe effect of landiolol on cerebral blood flow in patients undergoing off-pump coronary artery bypass surgery.
To examine the effect of landiolol on cerebral blood flow in patients with normal or deteriorated cardiac function. ⋯ Continuous administration of landiolol at a dose of 0.04 mg/kg/min after 1 min rapid i.v. administration at a dose of 0.125 mg/kg/min decreases HR without causing aggravation of CBF during treatment of intraoperative tachycardia in patients with normal and deteriorated cardiac function.

Comparative Study Clinical TrialIntrathecal catheterization after unintentional dural puncture during orthopedic surgery.
We investigated whether inserting an intrathecal catheter and leaving it in place for 24 h after an unintentional dural puncture in orthopedic patients reduced the incidence of post-dural puncture headache (PDPH). ⋯ Inserting an epidural catheter through the dural tear following an unintentional dural puncture and leaving it in place for 24 h significantly reduces the incidence of PDPH.

Randomized Controlled TrialKetamine eliminates propofol pain but does not affect hemodynamics during induction with double-lumen tubes.
Propofol injection during induction of anesthesia induces pain. Ketamine has been shown to reduce the injection pain. However, ketamine has unfavorable adverse effects, including increased secretion production and hemodynamic responses, which might induce pulmonary or hemodynamic adverse events, especially in patients undergoing lung surgery who require a double-lumen tube (DLT). The aim of this study was to determine whether ketamine can safely reduce propofol injection pain during induction of anesthesia for lung surgery. ⋯ One milligram per kilogram of ketamine completely eliminated pain associated with propofol injection without affecting hemodynamics during induction of anesthesia and oxygenation during OLV.
