Background: Postoperative nausea and vomiting (PONV) along with postoperative pain is one of the most frequently encountered complaints after the surgery. The goal of this study is to elucidate the probable high risks factors of PONV by making 24 hr-observations on 4008 patients undergone general anesthesia. Methods: PONV scores (0: no PONV; 1, nausea; 2, retching; 3, vomiting) and characteristics of patient, surgery, anesthesia were recorded by patient interview and chart review at post anest

Purpose: Total knee replacement is one of the most painful orthopedic procedures, and effective pain relief is essential for early mobility and discharge from hospital. The aim of this study was to evaluate whether addition of single-injection femoral nerve block to epidural analgesia would provide better postoperative pain control, compared to epidural analgesia alone, after total knee replacement. Materials and Methods: Thirty-eight patients received a single-injection femoral nerve block with

Background: The prevention of hypotension continues to be one of major challenges in spinal anesthesia (SA) for cesarean delivery. And prehydration is widely performed to prevent hypotension. However, some controversy exists over the types of fluid used for prehydration. Therefore, we investigated the effects of crystalloid versus colloid preload on the incidences of hypotension, and the notion that minimal local anesthetic used in combined spinal-epidural anesthesia (CSEA) could further decreas

Background: In the previous study, patients at high risk for postoperative nausea and vomiting (PONV) were identified by the Korean risk model. Consecutively, we investigated whether high-risk patients based on the Korean risk model could be managed with multiple prophylactic antiemetics. Methods: Patients scheduled for elective surgery under general anesthesia were classified in two risk groups (first group: high risk group, second group: very high risk group) by using the Korean risk model.

Abstract Background: Centrosome amplification (CA) which refers to presence of supernumerary or abnormally large centrosomes drives tumor progression by promoting chromosomal instability and the generation of aggressive tumor clones. Although the role of CA in cancer progression is well-defined, no studies have yet discussed how CA is induced in tumor cells. We report here that intra-tumoral hypoxia, which is considered one of the major contributors to intratumor heterogeneity, induces CA via HI

The use of neuroaxial blocks in patients with multiple sclerosis has been controversial, because the effect of local anesthetic drugs on the course of the disease is unclear. We report an obstetric patient with multiple sclerosis whose caesarian section was performed successfully under combined spinal-epidural anesthesia and postoperative pain control was managed using patient-controlled epidural analgesia. There were no exacerbation of neurologic symptoms and no relapse of disease at two month

We report a patient with a postpartum headache, who was later diagnosed with an intra cerebral hemorrhage. She underwent a cesarean section under the combined spinal-epidural anesthesia, and complained of a suspicious post-dural puncture headache (PDPH) in the puerperium. The headache was partially improved with analgesics and she was discharged. The day after discharge, the headache became aggravated and she visited our labor floor for further treatment. An epidural blood patch (EBP) was perfor

Abstract Background: The MRE11-RAD50-nibrin (MRN) complex participates in pathways of double-strand break induced DNA repair and cell cycle checkpoint control. RAD50 interacts with the MRE11 and NBS proteins, is involved in the maintenance of genomic integrity. The association of RAD50 mutation and breast cancer susceptibility has been reported in European patients. However, the impact of RAD50 mutation on a breast cancer predisposition among Koreans remains uncertain. In the current analysis, w
