Continuous glucose monitoring system in the operating room and intensive care unit: any difference according to measurement sites?

Given the benefit of glucose control in the perioperative period, we evaluated the accuracy and performance of the continuous glucose monitoring system (CGMS) depending on different measurement sites in the operating room (OR) and in the intensive care unit (ICU). Patients over 18 years of age scheduled for elective surgery and ICU admission were enrolled prospectively. Two CGMS sensors were inserted into the subcutaneous tissue of the proximal lateral thigh and the lateral abdomen.

Comparison of central venous catheterization techniques in pediatric patients: needle vs angiocath.

Background: A needle or an angiocath has been generally used as a route for inserting a guide wire during central venous catheterization. We compared the needle with the angiocath for ultrasound-guided central venous catheterization in pediatric patients concerning accuracy and easiness.

Methods: One hundred and thirty-two patients aged between 1 day and 5 years were randomized into the needle and the angiocath groups.

Comparison of the efficacy and safety of different doses of propacetamol for postoperative pain control after breast surgery.

Intravenous propacetamol has been shown to be effective for postoperative pain control. However, the recommendations regarding propacetamol doses for pain control are vague. The present study was performed to compare the efficacy and safety of propacetamol at a dose of 1 g or 2 g.

Pulse transit time shows vascular changes caused by propofol in children.

Pulse transit time (PTT) is the time that it takes for the arterial pulse pressure wave to travel from the aortic valve to the periphery. It is a simple noninvasive technique for evaluating vascular changes. This study investigated the vascular changes by propofol during the induction of anesthesia in pediatric patients with the measuring of PTT.

Postoperative pharyngolaryngeal adverse events with laryngeal mask airway (LMA Supreme) in laparoscopic surgical procedures with cuff pressure limiting 25 cmH₂O: prospective, blind, and randomised study.

To reduce the incidence of postoperative pharyngolaryngeal adverse events, laryngeal mask airway (LMA) manufacturers recommend maximum cuff pressures not exceeding 60 cmH₂O. We performed a prospective randomised study, comparing efficacy and adverse events among patients undergoing laparoscopic surgical procedures who were allocated randomly into low (limiting 25 cmH₂O, L group) and high (at 60 cmH₂O, H group) LMA cuff pressure groups with LMA Supreme. Postoperative pharyngolaryngeal adverse events were evaluated at discharge from postanaesthetic care unit (PACU) (postoperative day 1, POD 1) and 24 hours after discharge from PACU (postoperative day 2, POD 2).

Determination of mitral valve area with echocardiography, using intra-operative 3-dimensional versus intra- & post-operative pressure half-time technique in mitral valve repair surgery.

Background: We hypothesized that mitral valve areas (MVAs) with echocardiography, using 3D planimetry technique (measured at one point at maximal opening of mitral valve) versus pressure half-time technique (PHT, measured during entire diastolic phase) in mitral valve repair surgery (MVR) would be different.

Methods: Patients who had undergone MVR were retrospectively reviewed, and two different observers measured the MVAs using PHT and 3D planimetry technique. The MVAs derived from recorded medical data, using PHT and 3D planimetry technique were abbreviated to MVA-PHT1 and MVA-3D1, and data from the PHT and 3D planimetry techniques by observer A and observer B were determined as MVA-PHT2 and MVA-3D2, and MVA-PHT3 and MVA-3D3, respectively.

Relationship between complex regional pain syndrome and working life: a Korean study.

Complex regional pain syndrome affects the quality of life of the patient. The aim of this study was to investigate the epidemiological features of this syndrome and evaluate its effect on the patient's working life. We demonstrated that the disease has a male preponderance and is 3 times more likely to affect the lower extremities.

Radiation safety and education in the applicants of the final test for the expert of pain medicine.

Background: The C-arm fluoroscope is known as the most important equipment in pain interventions. This study was conducted to investigate the completion rate of education on radiation safety, the knowledge of radiation exposure, the use of radiation protection, and so on.

Methods: Unsigned questionnaires were collected from the 27 pain physicians who applied for the final test to become an expert in pain medicine in 2011.

A Study to Compare the Radiation Absorbed Dose of the C-arm Fluoroscopic Modes.

Background: Although many clinicians know about the reducing effects of the pulsed and low-dose modes for fluoroscopic radiation when performing interventional procedures, few studies have quantified the reduction of radiation-absorbed doses (RADs). The aim of this study is to compare how much the RADs from a fluoroscopy are reduced according to the C-arm fluoroscopic modes used.

Methods: We measured the RADs in the C-arm fluoroscopic modes including 'conventional mode', 'pulsed mode', 'low-dose mode', and 'pulsed + low-dose mode'.

Anesthetic managements for repair of atrial septal defect in a patient with Young-Simpson Syndrome: A case report.

Young-Simpson Syndrome (YSS) is a rare malformation syndrome characterized by facial dysmorphism, congenital heart abnormalities, congenital hypothyroidism and severe growth retardation. A 5-month-old girl was scheduled to undergo patch closure of atrial septal defect. She had been diagnosed with YSS preoperatively.

Early detection of ruptured bulla by capnography during off pump coronary artery bypass grafting surgery: A case report.

Capnography is monitoring of concentration or partial pressure of CO2 in respiratory gases. It provides information about CO2 production, pulmonary perfusion, alveolar ventilation, respiratory patterns and elimination of CO2 from the anesthesia circuit and ventilator. Thus it gives us a rapid and reliable method to detect life threatening conditions such as malposition of tracheal tube, ventilatory failure, circulatory failure and defective breathing circuits.

A heated humidifier does not reduce laryngo- pharyngeal complaints after brief laryngeal mask anesthesia.

Purpose: Warming and humidification of inspired gases is standard care for intubated patients whose lungs are ventilated mechanically for prolonged periods. We examined whether active humidification of inspired gases might reduce laryngo-pharyngeal discomfort in patients undergoing brief laryngeal mask airway (LMA) anesthesia.

Methods: In a prospective trial, 200 adult patients undergoing elective surgery under general anesthesia were randomly assigned to receive ventilation without airway warming and exogenous humidification (Group C-control), or active warming and humidification of inspired gases (Group HUM-humidified), using a humidifier with a heated wire circuit.
