BACKGROUND: Total knee arthroplasty (TKA) is associated with high rates of prolonged opioid use after surgery (10%-34%). By decreasing opioid use in the immediate postoperative period, perioperative nerve blockade has been hypothesized to decrease the risk of persistent opioid use. METHODS: Using health care utilization data, we constructed a sample of 120,080 patients undergoing TKA between 2002 and 2012 and used billing data to identify the utilization of peripheral or neuraxial blockade...

BACKGROUND: Increasing numbers of robotic hysterectomies (RH) are being performed. To provide ventilation (with pneumoperitoneum and steep Trendelenburg position) for these procedures, utilization of lung protective strategies with limiting airway pressures and tidal volumes is difficult. Little is known about the effects of intraoperative mechanical ventilation and high peak airway pressures on perioperative complications. We performed a retrospective review to determine whether patients undergoing RH had increased pulmonary complications compared to total abdominal hysterectomy (TAH)...

BACKGROUND: In this prospective double-blind randomized study, we evaluated the analgesic effect and potential effect on pregnancy rate of the nonsteroidal anti-inflammatory drug flurbiprofen axetil in patients undergoing ultrasound-guided transvaginal oocyte retrieval under propofol-remifentanil anesthesia. METHODS: A total of 200 patients scheduled to undergo ultrasound-guided transvaginal oocyte retrieval were randomly allocated to receive 1.5 mg/kg of flurbiprofen axetil (FA group) or placebo (control group) 30 minutes before the procedure...

BACKGROUND: Operating room (OR) utilization generally ranges from 50% to 75%. Inefficiencies can arise from various factors, including prolonged anesthesia preparation time, defined as the period from induction of anesthesia until patients are considered ready for surgery. Our goal was to use patient-related and procedure-related factors to develop a model predicting anesthesia preparation time. METHODS: From the electronic medical records of adults who had noncardiac surgery at the Cleveland Clinic Main Campus, we developed a model that used a dozen preoperative factors to predict anesthesia preparation time...

BACKGROUND: After cesarean delivery, postoperative pain management allows early rehabilitation and helps prevent postpartum depression and chronic pain. Our present prospective, randomized controlled, double-blind study assessed the duration and effect of intrathecal analgesia and continuous ropivacaine wound infiltration versus a control group after cesarean delivery. The primary outcome was analgesia duration, defined as time to first morphine request. Secondary outcomes were cumulative postoperative morphine consumption, number of patients who did not require IV morphine, incidence of adverse effects, and time to first ambulation...

BACKGROUND: Various different interventions can be used to reduce surgical blood loss; however, there is no "gold standard" for accurately measuring the volume of perioperative blood loss, and this makes it difficult to assess the efficacy of these interventions. METHODS: We used data from a previous multicenter double-blind randomized clinical trial in patients undergoing total hip arthroplasty in which we compared 2 regimens for administering tranexamic acid versus placebo...

BACKGROUND: Traditionally, mechanical ventilation is achieved via active lung inflation during inspiration and passive lung emptying during expiration. By contrast, the novel FLEX (FLow-controlled EXpiration) ventilator mode actively decreases the rate of lung emptying. We investigated whether FLEX can be used during intraoperative mechanical ventilation of lung-healthy patients. METHODS: In 30 adult patients scheduled for neurosurgical procedures, we studied respiratory system mechanics, regional ventilation, oxygenation, and hemodynamics during ventilation with and without FLEX at positive end-expiratory pressure (PEEP) of 5 and 7 cm H2O...

BACKGROUND: Although minor, a sore throat after endotracheal intubation can adversely affect patient satisfaction and postoperative function. We compared the effects of 2 endotracheal tube cuff shapes on postoperative sore throat. METHODS: One hundred ninety-one adult patients were included in the study. After induction of anesthesia, patients were randomized to endotracheal intubation with a conventional cylindrical-shaped cuff (Group C, n = 95) or a tapered-shaped cuff (Group T, n = 96)...

BACKGROUND: Vasopressors provide a rapid and effective approach to correct hypotension in the perioperative setting. Our group developed a closed-loop control (CLC) system that titrates phenylephrine (PHP) based on the mean arterial pressure (MAP) during general anesthesia. As a means of evaluating system competence, we compared the performance of the automated CLC with physicians. We hypothesized that our CLC algorithm more effectively maintains blood pressure at a specified target with less blood pressure variability and reduces the dose of PHP required...

BACKGROUND: We previously described the use of closed-loop feedback computer-controlled infusion of phenylephrine for maintaining blood pressure (BP) during spinal anesthesia for cesarean delivery. In this study, we report a modified system in which phenylephrine is delivered by intermittent boluses rather than infusion. We hypothesized that the use of computer-controlled boluses would result in more precise control of BP compared with infusions. METHODS: Two hundred fourteen healthy patients having spinal anesthesia for elective cesarean delivery were randomized to have their systolic BP maintained by phenylephrine administered by computer-controlled continuous infusion or computer-controlled intermittent boluses...

This study evaluated electric nerve stimulation as a nerve location tool. After eliciting motor response in 43 patients undergoing shoulder surgery, the needle tip's position, distance from the closest nerve, and spread of saline were evaluated using ultrasound imaging. The needle's tip resided 1 to 4 mm from the closest nerve in 21, in direct contact with it in 7, and 6 to 18 mm away in 15 patients. In 21 patients, subsequent saline dissection did not reach the brachial plexus. Thus, the success rate of electric nerve stimulation for correct needle-nerve distance identification was 48...
