Design: Prospective, randomized controlled trial.

Setting: A single tertiary care center from October 2019 and September 2020.

Domino living donor liver transplantation of familial amyloid polyneuropathy patient - A case report.

Background: Familial amyloid polyneuropathy (FAP) is caused by mutation in a gene transcribing transport protein produced mainly by the liver. Liver transplantation is required to stop FAP progression, but the pathology causes anesthetic management challenges.

Case: We report a case of domino living donor liver transplantation in an FAP patient.

Intraoperative dexmedetomidine attenuates norepinephrine levels in patients undergoing transsphenoidal surgery: a randomized, placebo-controlled trial.

Background: Dexmedetomidine has sympatholytic effects. We investigated whether dexmedetomidine could attenuate stress responses in patients undergoing endoscopic transnasal transseptal transsphenoidal surgery.

Methods: Forty-six patients were randomized to receive a continuous infusion of 0.

Neutral Position Facilitates Nasotracheal Intubation with a GlideScope Video Laryngoscope: A Randomized Controlled Trial.

The optimal head position for GlideScope facilitated nasotracheal intubation has not yet been determined. We compared the neutral and sniffing positions to establish the degree of intubation difficulty. A total of 88 ASA I-II patients requiring nasotracheal intubation for elective dental surgery with normal airways were divided into two groups according to head position, neutral position (group N), and sniffing position (group S).

Bilateral single-injection erector spinae plane block versus intrathecal morphine for postoperative analgesia in living donor laparoscopic hepatectomy: a randomized non-inferiority trial.

Background: Intrathecal morphine (ITM) provides effective postoperative analgesia in living donor hepatectomy but has significant adverse effects. Studies support the efficacy of erector spinae plane (ESP) blocks in laparoscopic abdominal surgery; we therefore hypothesized that they would provide non-inferior postoperative analgesia compared with ITM and reduce postoperative nausea/vomiting and pruritus. We conducted a randomized, controlled, non-inferiority trial to compare the analgesic efficacy of ITM and bilateral single-injection ESP blocks in laparoscopic donor hepatectomy.

Superior Trunk Block Provides Noninferior Analgesia Compared with Interscalene Brachial Plexus Block in Arthroscopic Shoulder Surgery.

Background: Interscalene brachial plexus block of the C5-C6 roots provides highly effective postoperative analgesia after shoulder surgery but usually results in hemidiaphragmatic paresis. Injection around the superior trunk of the brachial plexus is an alternative technique that may reduce this risk. The authors hypothesized that the superior trunk block would provide noninferior postoperative analgesia compared with the interscalene block and reduce hemidiaphragmatic paresis.

Postoperative pain control after the use of dexmedetomidine and propofol to sedate patients undergoing ankle surgery under spinal anesthesia: a randomized controlled trial.

Dexmedetomidine is widely used for conscious sedation in patients undergoing lower-extremity surgery under regional anesthesia. We evaluated the postoperative analgesic effects of intravenous dexmedetomidine given during ankle surgery under spinal anesthesia. Forty-three participants underwent repair of lateral angle ligaments under spinal anesthesia.

Driving Pressure during Thoracic Surgery: A Randomized Clinical Trial.

What We Already Know About This Topic: Driving pressure (plateau minus end-expiratory airway pressure) is a target in patients with acute respiratory distress syndrome, and is proposed as a target during general anesthesia for patients with normal lungs. It has not been reported for thoracic anesthesia where isolated, inflated lungs may be especially at risk.

What This Article Tells Us That Is New: In a double-blinded, randomized trial (292 patients), minimized driving pressure compared with standard protective ventilation was associated with less postoperative pneumonia or acute respiratory distress syndrome.

Portland Intensive Insulin Therapy During Living Donor Liver Transplantation: Association with Postreperfusion Hyperglycemia and Clinical Outcomes.

Many liver transplant recipients experience intraoperative hyperglycemia after graft reperfusion. Accordingly, we introduced the Portland intensive insulin therapy (PoIIT) in our practice to better control blood glucose concentration (BGC). We evaluated the effects of PoIIT by comparing with our conventional insulin therapy (CoIT).

Effective Dose of Intravenous Dexmedetomidine to Prolong the Analgesic Duration of Interscalene Brachial Plexus Block: A Single-Center, Prospective, Double-Blind, Randomized Controlled Trial.

Background And Objectives: Intravenous (IV) dexmedetomidine (DEX) is reported to prolong the analgesic duration after single-shot interscalene brachial plexus block (ISBPB). However, the effective analgesic dose of IV DEX remains undetermined. Therefore, we aimed to elucidate the clinically relevant dose of IV DEX to prolong the analgesic duration of ISBPB.

Utility of stroke volume variation measured using non-invasive bioreactance as a predictor of fluid responsiveness in the prone position.

The aim of this prospective study was to evaluate the usefulness of stroke volume variation (SVV) derived from NICOM to predict fluid responsiveness in the prone position. Forty adult patients undergoing spinal surgery in the prone position were included in this study. We measured SVV from NICOM (SVV) and FloTrac™/Vigileo™ systems (SVV), and pulse pressure variation (PPV) using automatic (PPV) and manual (PPV) calculations at four time points including supine and prone positions, and before and after fluid loading of 6 ml kg colloid solution.

Bioreactance Is Not Interchangeable with Thermodilution for Measuring Cardiac Output during Adult Liver Transplantation.

Background: Thermodilution technique using a pulmonary artery catheter is widely used for the assessment of cardiac output (CO) in patients undergoing liver transplantation. However, the unclearness of the risk-benefit ratio of this method has led to an interest in less invasive modalities. Thus, we evaluated whether noninvasive bioreactance CO monitoring is interchangeable with thermodilution technique.

Optimal head rotation and puncture site for internal jugular vein cannulation after laryngeal mask airway insertion.

Introduction: We studied the effect of head rotation on the relative position of the right common carotid artery (CCA) and the right internal jugular vein (IJV) in patients with laryngeal mask airway (LMA) insertion to evaluate the accuracy of anatomical landmarks for right IJV cannulation.

Methods: We simulated needle insertion to the right IJV on sonograms via the central landmark approach and an approach using the external jugular vein, in patients with LMA insertion (n = 50) or endotracheal intubation (E-tube, n = 50). Overlap index and successful simulation rates were measured according to the different degrees of head rotation.

Glycemic responses to intermittent hepatic inflow occlusion in living liver donors.

The occurrence of glycemic disturbances has been described for patients undergoing intermittent hepatic inflow occlusion (IHIO) for tumor removal. However, the glycemic responses to IHIO in living liver donors are unknown. This study investigated the glycemic response to IHIO in these patients and examined the association between this procedure and the occurrence of hyperglycemia (blood glucose > 180 mg/dL).

Intraoperative hyperglycemia during liver resection: predictors and association with the extent of hepatocytes injury.

Background: Patients undergoing liver resection are at risk for intraoperative hyperglycemia and acute hyperglycemia is known to induce hepatocytes injury. Thus, we aimed to evaluate whether intraoperative hyperglycemia during liver resection is associated with the extent of hepatic injury.

Methods: This 1 year retrospective observation consecutively enrolled 85 patients undergoing liver resection for hepatocellular carcinoma.

Effect of pre-warmed intravenous fluids on perioperative hypothermia and shivering after ambulatory surgery under monitored anesthesia care.

Purpose: The aim of this study was to evaluate the effects of pre-warmed (approximately 41 °C) intravenous fluids (IV) on perioperative hypothermia and postoperative shivering in female patients undergoing short, ambulatory urological surgery under monitored anesthesia care (MAC).

Methods: Patients between the ages of 35 and 80 years were randomly assigned to either the pre-warmed (n = 27) or the room temperature (n = 26) group. According to group allocation, either pre-warmed IV fluids that had been stored in a warming cabinet for at least 8 h or room temperature IV fluids were administered intraoperatively up to approximately 600-700 ml, including a bolus infusion of 10 ml/kg within 20 min.

Pulse pressure variation and stroke volume variation to predict fluid responsiveness in patients undergoing carotid endarterectomy.

Background: During carotid endarterectomy (CEA), hemodynamic stability and adequate fluid management are crucial to prevent perioperative cerebral stroke, myocardial infarction and hyperperfusion syndrome. Both pulse pressure variation (PPV) and stroke volume variation (SVV), dynamic preload indices derived from the arterial waveform, are increasingly advocated as predictors of fluid responsiveness in mechanically ventilated patients. The aim of this study was to evaluate the accuracy of PPV and SVV for predicting fluid responsiveness in patients undergoing CEA.

The effect of midazolam dose and age on the paradoxical midazolam reaction in Korean pediatric patients.

Background: Although midazolam administration may occasionally induce a paradoxical episode, such as threatened crying and violent behavior in children, systematic studies on the causes of paradoxical reaction are limited. We investigated the effect of children's age and a dose of midazolam on the paradoxical reaction.

Methods: A total of one hundred sixty four children of 1-3 years and 3-5 years, were enrolled in this study.

Prospective, randomized study of ropivacaine wound infusion versus intrathecal morphine with intravenous fentanyl for analgesia in living donors for liver transplantation.

Postoperative analgesia and care for living liver donors have become particular interests for clinicians as the use of living donor liver transplantation has increased. Local anesthetic-based analgesia has been known to provide effective pain control. In this prospective, randomized study, we compared the postoperative analgesic efficacy of local anesthetic-based analgesia (PainBuster) with the efficacy of opioid-based analgesia [intrathecal morphine (ITM) with intravenous (IV) fentanyl] in liver donors.

Liver transplantation using grafts of living donors with isolated unconjugated hyperbilirubinemia: a matched case-control study.

Unconjugated bilirubin has shown both cytotoxic and cytoprotective effects, acting as either an oxidant or an antioxidant. Elevated unconjugated bilirubin with otherwise normal, so-called isolated unconjugated hyperbilirubinemia (IUHB), is encountered frequently in living liver donor evaluation. However, the significance of IUHB on transplantation-related outcomes has not been clarified in donors and recipients.

Intra-operative cardiac arrests during liver transplantation - a retrospective review of the first 15 yr in Asian population.

Although many report intra-operative cardiac arrests (ICAs) in liver transplantation (LT), the incidence, major causes, and outcome remain unclear. We aimed to investigate retrospectively, the incidence, nature, and outcome of ICA in Asian population and to identify risk factors for ICA. Consecutive 1071 LTs in an institution during 1996-2011 (adult 920, pediatric 151/living donor liver transplantation, LDLT 841, deceased donor liver transplantation, DDLT 230) were reviewed.

Epinephrine decreases the dose of hyperbaric bupivacaine necessary for tourniquet pain blockade during spinal anesthesia for total knee replacement arthroplasty.

Purpose: We quantified the dose-sparing effect of epinephrine by comparing the median effective dose (ED(50)) of intrathecal hyperbaric bupivacaine co-administered with epinephrine with the ED(50) of intrathecal hyperbaric bupivacaine alone.

Methods: Three groups were randomly generated from 162 patients undergoing total knee replacement arthroplasty under combined spinal and epidural anesthesia: Group B (bupivacaine), Group BE1 (bupivacaine plus epinephrine 100 μg), and Group BE2 (bupivacaine plus epinephrine 200 μg). Each group was further divided by bupivacaine doses of 6, 7, 8, 9, 10, or 11 mg.

Effect of intraoperative lidocaine on anesthetic consumption, and bowel function, pain intensity, analgesic consumption and hospital stay after breast surgery.

Background: Perioperative lidocaine infusion improves postoperative outcomes, mostly after abdominal and urologic surgeries. Knowledge of the effect of lidocaine on peripheral surgeries is limited. Presently, we investigated whether intraoperative lidocaine infusion reduced anesthetic consumption, duration of ileus, pain intensity, analgesic consumption and hospital stay after breast plastic surgeries.
