Influence of saline-based hydroxyethyl starch on umbilical cord blood electrolytes.

Hydroxyethyl starch (HES) is widely used to prevent and treat spinal anesthesia-induced hypotension during cesarean section. However, the use of saline-based HES may lead to hyperchloremia. This study aimed to clarify the effects of saline-based HES on umbilical cord chloride level at delivery. We retrospectively analyzed 93 consecutive single-pregnancy patients who underwent cesarean section with combined spinal-epidural anesthesia. The patients were divided into two groups, depending on the use of 6% HES ...

Inadvertent misplacement of the inferior vena cava.

Outcomes of physician patients after non-cardiac surgery: a registry analysis.

When physicians become patients, they may expect special privileges, extra attention from caregivers, and non-routine treatments. Consequently, physician patients may not be treated per routine-which possibly worsens care rather than improving it. We thus tested the primary hypothesis that in-hospital mortality and major complications after non-cardiac surgery are more common in physician patients than in non-physician patients.

Erratum to: Remifentanil for labor analgesia: a comprehensive review.

Cost comparison of intrathecal morphine to intravenous patient-controlled analgesia for the first 24 h post cesarean delivery: a retrospective cohort study.

Intrathecal morphine provides superior pain control for patients undergoing cesarean delivery when compared to intravenous opioid patient-controlled analgesia. However, no study has assessed the overall cost associated with each modality as a primary outcome. The aim of this study is to determine the overall cost of each modality for the first 24 h post cesarean delivery.

Continuous intravenous analgesia with fentanyl or morphine after gynecological surgery: a cohort study.

This retrospective study aims to compare postoperative pain relief offered by continuous intravenous infusion of either fentanyl or morphine.

Analysis of actual pressure point using the power flexible capacitive sensor during chest compression.

In chest compression for cardiopulmonary resuscitation (CPR), the lower half of the sternum is pressed according to the American Heart Association (AHA) guidelines 2010. These have been no studies which identify the exact location of the applied by individual chest compressions. We developed a rubber power-flexible capacitive sensor that could measure the actual pressure point of chest compression in real time. Here, we examined the pressure point of chest compression by ambulance crews during CPR using a m...

Prediction of in-hospital mortality and morbidity using high-sensitivity C-reactive protein after burr hole craniostomy.

The purpose of this study was to assess whether preanesthetic laboratory values can predict in-hospital mortality and morbidity in patients who have undergone burr hole craniostomy due to chronic subdural hematoma.

Bilateral hypoglossal nerve paralysis following elongated styloid process resection: case report.

We report a case of anesthetic management of a 43-year-old patient with Eagle's syndrome (ES) in whom post-extubation acute airway obstruction occurred due to bilateral hypoglossal nerve paralysis. After an accurate examination, elongated bilateral stylohyoid ligament was observed and surgical resection was planned. After completion of the surgery following extubation, significant dysfunction in swallowing, speech function, and tongue motion was observed. The clinical situation was evaluated as bilateral hy...

Effects of oral carbohydrate with amino acid solution on the metabolic status of patients in the preoperative period: a randomized, prospective clinical trial.

Enhanced recovery after surgery is increasingly desired nowadays, and preoperative nutrient intake may be beneficial for this purpose. In this study, we investigated whether the intake of preoperative carbohydrate with amino acid (ONS) solution can improve starvation status and lipid catabolism before the induction of anesthesia.

Management of cognition as reported in Japanese historical documents and modern anesthesiology research papers.

Sarcopenia in critically ill patients.

Sarcopenia occurring as a primary consequence of aging and secondary due to certain medical problems including chronic disease, malnutrition and inactivity is a progressive generalized loss of skeletal muscle mass, strength and function. The prevalence of sarcopenia increases with aging (approximately 5-13 % in the sixth and seventh decades). However, data showing the prevalence and clinical outcomes of sarcopenia in intensive care units (ICUs) are limited. A similar condition to sarcopenia in the ICU, cal...

Analgesic effect of a single dose of betamethasone after ambulatory knee arthroscopy: a randomized controlled trial.

Glucocorticoids are reported to improve postoperative analgesia. The purpose of the study was to investigate whether a preoperative, single dose of betamethasone could reduce pain after ambulatory arthroscopic knee surgery.

Roles of endotracheal tubes and slip joints in respiratory pressure loss: a laboratory study.

The endotracheal tube (ETT) constitutes a significant component of total airway resistance. However, a discrepancy between measured and theoretical values has been reported in airway resistance through ETTs. The causes of the discrepancy were estimated by physical and rheological simulations.

Controversies in the temperature management of critically ill patients.

Although body temperature is a classic primary vital sign, its value has received little attention compared with the others (blood pressure, heart rate, and respiratory rate). This may result from the fact that unlike the other primary vital signs, aging and diseases rarely affect the thermoregulatory system. Despite this, when humans are exposed to various anesthetics and analgesics and acute etiologies of non-infectious and infectious diseases in perioperative and intensive care settings, abnormalities ma...

The comparison of adductor canal block with femoral nerve block following total knee arthroplasty: a systematic review with meta-analysis.

Although several studies have compared the clinical efficacy of an adductor canal block (ACB) to that of a femoral nerve block (FNB) for analgesia after total knee arthroplasty (TKA), disputes mainly exist in the recovery of quadriceps strength and mobilization ability between the two methods. The aim of the present study was to compare, in a systematic review and meta-analysis, the clinical efficacy of ACB with that of FNB.

Switching therapy from intravenous beta blocker to bisoprolol transdermal patch for atrial fibrillation tachycardia.

Beta-blockers are important for severe-status patients with atrial fibrillation-related tachycardia. Beta 1-selective intravenous injection are routinely used, but long-term administration is difficult due to cost-performance- or management-related issues. A bisoprolol patch, a beta-blocker to be percutaneously absorbed, recently became commercially available in Japan. As it may facilitate effective absorption and a mild elevation of the blood concentration, we retrospectively analyzed 16 patients with atri...

Acute pain trajectories and the persistence of post-surgical pain: a longitudinal study after total hip arthroplasty.

The aim of this study was to explore acute movement-evoked postoperative pain intensity trajectories over the first 5 days after total hip arthroplasty (THA) and to examine how these pain trajectories are associated with pain-related outcomes 6 weeks and 6 months later.

Pulsed radiofrequency on radial nerve under ultrasound guidance for treatment of intractable lateral epicondylitis.

Lateral epicondylitis is a painful and functionally limiting disorder. Although lateral elbow pain is generally self-limiting, in a minority of people symptoms persist for a long time. When various conservative treatments fail, surgical approach is recommended. Surgical denervation of several nerves that innervate the lateral humeral epicondyle could be considered in patients with refractory pain because it denervates the region of pain. Pulsed radiofrequency is a minimally invasive procedure that improves ...

Fluoroscopically guided tunneled trans-caudal epidural catheter technique for opioid-free neonatal epidural analgesia.

Epidural analgesia confers significant perioperative advantages to neonates undergoing surgical procedures but may be very technically challenging to place using a standard interlaminar loss-of-resistance to saline technique given the shallow depth of the epidural space. Thoracic epidural catheters placed via the caudal route may reduce the risk of direct neural injury from needle placement, but often pose higher risks of infection and/or improper positioning if placed without radiographic guidance. We pres...

Comparison of fluid leakage across endotracheal tube cuffs using a three-dimensional printed model of the human trachea.

The objective of this study was to compare fluid leakage across endotracheal tube cuffs using a three-dimensional (3D)-printed human tracheal model that anatomically simulates the human trachea. We made two models based on computed tomography data of the neck and chest. Using a Mallinckrodt Hi-Lo™ (HL), ThinCuff(®) (TC), and Mallinckrodt TaperGuard™ (TG), we sequentially measured the amount of fluid leakage across each endotracheal tube cuff after applying saline or viscous liquid above the cuff. The T...

Computational simulation and comparison of prothrombin complex concentrate dosing schemes for warfarin reversal in cardiac surgery.

Prothrombin complex concentrate (PCC) is increasingly used for acute warfarin reversal. We hypothesized that computational modeling of thrombin generation (TG) could be used to optimize the timing and dose of PCC during hemodilution induced by cardiopulmonary bypass (CPB).

Limitation in monitoring depth of anesthesia: a case report.

Although we describe a clinical situation that most likely occurs in hundreds of operatory rooms in the world, we report this case as provocation. It concerns an unexpected awakening from an appropriate depth of anesthesia, although the BIS monitor showed a BIS index of less than 50 for a prolonged period before and after the event. Approximately 30 min after induction of anesthesia, the patient had a hypothetic sudden arousal of consciousness, with spontaneous movements, facial muscle activation, intolera...
