Unexpected difficulty in ventilating the lungs after tracheal intubation -A case report-
We experienced difficulty in ventilating the lungs of a patient after tracheal intubation. After intubation, an insufficient amount of tidal volume (VT) was delivered to the patient and the fiberoptic bronchoscopic examination identified partial abutment of the endotracheal tube (ETT) orifice against the tracheal wall. After various attempts to correctly place the ETT, a double-lumen endotracheal tube was placed to achieve a sufficient VT. It is important to notice that even an appropriately placed ETT may get obstructed due to the left sided bevel at its tip
The relationship between symphysis-fundal height and intravenous ephedrine dose in spinal anesthesia for elective cesarean section
Pulmonary thromboembolism after tourniquet inflation under spinal anesthesia -A case report-
Pulmonary thromboembolism is one of the most important causes of morbidity and mortality in patients undergoing lower extremity orthopedic surgery. Early diagnosis and appropriate management are important clinical challenges. In this case, massive pulmonary embolism causing sudden cardiac arrest was attributed to use of tourniquet inflation during lower extremity orthopedic surgery. Resuscitation procedures were initiated and transesophageal echocardiography revealed pulmonary thromboembolism. Patients with high suspicion for the presence of deep vein thrombus must be monitored thoroughly during limb exsanguinations
Subarachnoid and Intraventricular Hemorrhage due to Ruptured Aneurysm after Combined Spinal-Epidural Anesthesia
A patient received combined spinal-epidural anesthesia for a scheduled total knee arthroplasty. After an injection of spinal anesthetic and ephedrine due to a decrease in blood pressure, the patient developed a severe headache. The patient did not respond to verbal command at the completion of the operation. A brain CT scan revealed massive subarachnoid and intraventricular hemorrhages, and a CT angiogram showed a ruptured aneurysm. Severe headaches should not be overlooked in an uncontrolled hypertensive patient during spinal anesthesia because it may imply an intracranial and intraventricular hemorrhage due to the rupture of a hidden aneurysm
Comparison of fentanyl and sufentanil added to 0.5% hyperbaric bupivacaine for spinal anesthesia in patients undergoing cesarean section
Intrathecal meperidine reduces intraoperative shivering during transurethral prostatectomy in elderly patients
BACKGROUND: Shivering is a frequent event during the perioperative period. We performed a prospective, randomized, double-blind study to determine whether intrathecal meperidine (0.2 mg/kg) decreases the incidence and intensity of shivering after spinal anesthesia for transurethral operations.
METHODS: Fifty patients scheduled for elective transurethral resection operations under spinal anesthesia were randomly allocated to two groups. Spinal anesthesia consisted of 0.5% hyperbaric bupivacaine 8 mg and, mperidine (0.2 mg/kg) (meperidine group) or, normal saline (saline group). Data collection, including sensory block level (by pinprick), blood pressure, heart rate, sublingual temperature, incidence and intensity of shivering, pruritus, nausea, and vomiting was performed at 10 minute intervals.
RESULTS: The incidence and intensity of shivering was significantly less in the meperidine group than saline group (P = 0.012 and P = 0.008, for incidence and intensity, respectively). However, pruritus was more common in the meperidine group compared with the saline group (16% vs. 0%, P < 0.05).
CONCLUSIONS: The addition of meperidine 0.2 mg/kg to intrathecal bupivacaine lowers the incidence and severity of shivering during transurethral prostatectomy in elderly patientsope
Cyclooxygenase-2 Overexpression in Chronic Inflammation Associated with Benign Prostatic Hyperplasia: Is It Related to Apoptosis and Angiogenesis of Prostate Cancer?
Comparison of Ezetimibe/Simvastatin 10/20 mg Versus Atorvastatin 20 mg in Achieving a Target Low Density Lipoprotein-Cholesterol Goal for Patients With Very High Risk
Genetic Traceability of Black Pig Meats Using Microsatellite Markers
Pork from Jeju black pig (population J) and Berkshire (population B) has a unique market share in Korea because of their high meat quality. Due to the high demand of this pork, traceability of the pork to its origin is becoming an important part of the consumer demand. To examine the feasibility of such a system, we aim to provide basic genetic information of the two black pig populations and assess the possibility of genetically distinguishing between the two breeds. Muscle samples were collected from slaughter houses in Jeju Island and Namwon, Chonbuk province, Korea, for populations J and B, respectively. In total 800 Jeju black pigs and 351 Berkshires were genotyped at thirteen microsatellite (MS) markers. Analyses on the genetic diversity of the two populations were carried out in the programs MS toolkit and FSTAT. The population structure of the two breeds was determined by a Bayesian clustering method implemented in structure and by a phylogenetic analysis in Phylip. Population J exhibited higher mean number of alleles, expected heterozygosity and observed heterozygosity value, and polymorphism information content, compared to population B. The FIS values of population J and population B were 0.03 and −0.005, respectively, indicating that little or no inbreeding has occurred. In addition, genetic structure analysis revealed the possibility of gene flow from population B to population J. The expected probability of identify value of the 13 MS markers was 9.87×10−14 in population J, 3.17×10−9 in population B, and 1.03×10−12 in the two populations. The results of this study are useful in distinguishing between the two black pig breeds and can be used as a foundation for further development of DNA markers
