Rapid correction of severe hyponatremia and control of subsequent overcorrection in operative hysteroscopy intravascular absorption syndrome: A case report.

Rationale: Operative hysteroscopy intravascular absorption syndrome (OHIAS) results from systemic absorption of hypotonic solution during hysteroscopy, which may induce severe hyponatremia within hours. Depending on the serum sodium (Na+) level, this can be life-threatening and requires prompt and careful remedial treatment.

Patient Concerns And Diagnoses: A 53-year-old woman underwent hysteroscopic myomectomy for submucosal leiomyoma.

Influence of body fatness on propofol requirements for loss of consciousness in target-controlled infusion: A STROBE-compliant study.

This prospective observational study evaluated the effects of body fat on the pharmacologic effect of propofol. Hundred patients aged 18 to 75 years who were scheduled to undergo orthopedic surgery under regional block were enrolled. All participants underwent bioelectrical impedance analysis and were allocated into 2 groups: the high and normal adiposity group, according to percent body fat.

Unusual presentations of thoracic disc herniation treated by thoracic epidural block: Case reports.

Rationale: Herniation of the thoracic intervertebral disc (HTD) is a rare disease that accounts for <1% of all disc herniations. Physicians may make diagnostic errors due to the variable clinical features and limited experience of HTD. In this report, we present 2 unusual cases of HTD.

Bleeding complications associated with the molecular adsorbent recirculating system: a retrospective study.

Background: The molecular adsorbent recirculating system (MARS) is a hepatic replacement system that supports excretory liver function in patients with liver failure. However, since MARS has been employed in our hospital, bleeding complications have occurred in many patients during or after MARS. The objective of this study was to determine how MARS affects coagulopathy and identify specific factors associated with bleeding complications.

The effect of an eye mask on midazolam requirement for sedation during spinal anesthesia: a randomized controlled trial.

Background: Midazolam is frequently used for sedation during spinal anesthesia. However, external environmental factors, such as bright surgical lights, may hamper patient relaxation, which may lead to an increase in the dose of midazolam required and the likelihood of adverse drug effects. We investigated whether using an eye mask to block the external environment could reduce midazolam requirements during spinal anesthesia.

Prediction of successful caudal epidural injection using color Doppler ultrasonography in the paramedian sagittal oblique view of the lumbosacral spine.

Background: Ultrasound-guided caudal epidural injection (CEI) is limited in that it cannot confirm drug distribution at the target site without fluoroscopy. We hypothesized that visualization of solution flow through the inter-laminar space of the lumbosacral spine using color Doppler ultrasound alone would allow for confirmation of drug distribution. Therefore, we aimed to prospectively evaluate the usefulness of this method by comparing the color Doppler image in the paramedian sagittal oblique view of the lumbosacral spine (LS-PSOV) with the distribution of the contrast medium observed during fluoroscopy.

The efficacy of selective nerve root block for the long-term outcome of postherpetic neuralgia.

Background: Several nerve blocks can reduce the incidence of postherpetic neuralgia (PHN) as well as relieve acute zoster-related pain, but the long-term outcome of PHN has not been clearly determined. This study investigated the efficacy of selective nerve root block (SNRB) for herpes zoster (HZ) on the long-term outcome of PHN.

Methods: We prospectively conducted an interview of patients who had undergone an SNRB for HZ from January 2006 to December 2016 to evaluate their long-term PHN status.

Effects of preoperative oral carbohydrate administration on patient well-being and satisfaction in thyroid surgery.

Background: Although the positive effects of preoperative oral carbohydrate administration on clinical outcomes following major surgery have been reported continuously, there are few investigations of them in minor surgical patients. The present study was designed to examine the effects of preoperative oral carbohydrate administration on patient well-being and satisfaction in patients undergoing thyroidectomy.

Methods: Fifty adults aged 20-65 years and scheduled for elective thyroidectomy in first schedule in the morning were allocated to one of two groups.
