OBJECTIVE: Pain that occurs following gynecological laparoscopic surgery is a main cause for prolonged hospitalization. As a solution, various intravenous patient-controlled analgesia (IV PCA) systems have been used to control postoperative pain. This study explored the relationship between the dose of the ramosetron used to control postoperative nausea and vomiting (PONV) and its effect when oxycodone was used as the IV PCA. METHODS: Ninety-two patients (age, 18–70 years) undergoing gynecological laparoscopic surgery received oxycodone as IV PCA and were divided into the RB and RM group. Towards the end of surgery, the RB group patients were given 0.3 mg ramosetron as an IV bolus, and those in the RM group were given 0.3 mg ramosetron plus and additional 0.6 mg as IV PCA. The degree of PONV, postoperative pain, and pain felt during coughing were observed for 0.5, 2, 4, 8, 24, and 48 hours postoperatively. Patient satisfaction and comfort were assessed at 24 and 48 hours. RESULTS: No differences in operation time, anesthesia period, or amounts of propofol and remifentanil used were observed between the groups. IV PCA demand, severity of PONV, postoperative pain, and coughing pain were also similar between the groups. Patient comfort was similar between the groups at 24 and 48 hours postoperatively. CONCLUSION: No difference in the incidence of PONV was detected between patients who used only 0.3 mg ramosetron as an intravenous bolus and those who received an additional 0.6 mg ramosetron mixed in IV PCA when oxycodone was offered as the IV PCA after undergoing gynecological laparoscopic surgery.

Percutaneous arterial catheterization is a widely used technique for continuous hemodynamic monitoring and arterial blood gas analysis. There are various complications such as hemorrhage, hematoma, infection, and thrombosis. We performed a catheterization procedure to confirm that the lateral circulation of the radial artery was sufficient. The arterial blood pressure waveform was damped after catheterization. Immediately after removal of the catheter, ultrasonography and Doppler were used to confirm the formation of total thrombus in the radial artery. A thrombus was found in the radial artery and disappeared at 3 days postoperatively.

Hypovolemic shock and septic shock present similar symptoms, such as increased heart rate and decreased blood pressure. However, the two conditions have different causes, mechanisms, and treatment approaches. Early differentiation between the two conditions can have a positive impact on patient prognosis. In this case, the patient underwent a right ovarian cystectomy due to a teratoma torsion during a previous pregnancy, followed by treatment for a postoperative infection. While recovering, the patient underwent an emergency cesarean section due to sudden severe abdominal pain. After the surgery, unstable vital signs were suggestive of hypovolemia due to massive bleeding from the cesarean section. Therefore, fluid infusion and blood transfusion were initiated. The vital signs did not improve. So, the patient was reassessed. Body temperature and the previously elevated C-reactive protein levels were remeasured. The results of the reassessment indicated a septic condition due to previous infection. The patient was prescribed additional vasopressors and antibiotics for the following week. Subsequently, the patient’s vital signs stabilized, and the treatment was discontinued.

BACKGROUND: Head lift (HL) for 5 seconds and tongue depressor (TD) test have been used for diagnosis of the residual block after using the nondepolarizing muscle relaxants. We investigated validity and reliability of HL, TD, and both of them (HLTD). METHODS: Four-hundred-thirteen patients were enrolled in this study. Neuromuscular blockade was maintained with rocuronium and reversed with pyridostigmine and glycopyrrolate. TOF ratio was quantified by acceleromyograph in the recovery room. HL and TD test were performed in the patients who could respond to verbal command of the investigator. We analyzed the sensitivity, specificity, positive and negative predictive value, positive and negative likelihood ratio, area under the cure (AUC) from ROC analysis and kappa statistics. RESULTS: Prevalences of residual block were 13%, 32% and 78% at 0.7, 0.9 and 1.0 of TOF ratio cutoff value, respectively. Specificity was good for HL (79.7-86.8%), TD (94.2-97.8%) and HLTD (77.8-85.7%), but sensitivity was not. Positive predictive value was higher in TD than HL and HLTD, and negative predictive value was similar among them. Positive and negative likelihood ratio was higher in TD than HL and HLTD. AUC had no difference among HL, TD and LTD. Kappa statistics were showed minimal or moderate relationship between clinical test and train of four responses. CONCLUSIONS: We concluded that HL, TD and HLTD were not good tools for diagnosis of the residual block in a view of validity and reliability.

BACKGROUND: The Masimo Radical 7 (Masimo Corp., Irvine, CA, USA) pulse co-oximeter(R) noninvasively determines the hemoglobin concentration using the principle of transcutaneous spectrophotometry. We compared hemoglobin levels determined using this device (SpHb) with those determined using an invasive laboratory-based technique (tHb) during spinal anesthesia. METHODS: Thirty patients received spinal anesthesia with 0.5% hyperbaric bupivacaine. The pulse co-oximeter probe was mounted on the second toe, and arterial blood samples were obtained from a radial artery catheter. SpHb, tHb, and perfusion index (PI) values were recorded before and 20 and 40 min after intrathecal injection of bupivacaine. RESULTS: Before spinal anesthesia, the SpHb and tHb showed a significant difference of -2.86 +/- 1.56 g/dl (P < 0.005), but no significant differences were found between tHb and SpHb at 20 and 40 min after spinal anesthesia (-0.16 +/- 2.45 g/dl and 0.29 +/- 2.68 g/dl). Additionally, PI was significantly increased at 20 and 40 min after spinal anesthesia compared to the pre-anesthetic value (P < 0.001). CONCLUSIONS: The toe is not the monitoring site for pulse co-oximetry in adult patients, but the pulse co-oximetry on the toe appears to be appropriate as a noninvasive hemoglobin monitoring device after spinal anesthesia.
