Background: The purpose of this study was to evaluate the effect of palonosetron combined with dexamethasone for the prevention of PONV compared to dexamethasone alone in women who received intravenous patient-controlled analgesia (IV-PCA) using fentanyl. Methods: In this randomized, double-blinded, placebo-controlled study, 204 healthy female patients who were scheduled to undergo elective surgery under general anesthesia followed by IV-PCA for postoperative pain control were enrolled. Patients were divided into two groups: the PD group (palonosetron 0.075 mg and dexamethasone 5 mg IV; n = 102) and the D group (dexamethasone 5 mg IV; n = 102). The treatments were given after the induction of anesthesia. The incidence of nausea, vomiting, severity of nausea, and the use of rescue anti-emetics during the first 48 hours after surgery were evaluated. Results: The incidence of PONV was significantly lower in the PD group compared with the D group during the 0–24 hours (43 vs. 59%) and 0–48 hours after surgery (45 vs. 63%) (P < 0.05). The severity of nausea during the 6–24 hours after surgery was significantly less in the PD group compared with the D group (P < 0.05). The incidence of rescue antiemetic used was significantly lower in the PD group than in the D group during the 0–6 hours after surgery (13.1 vs. 24.5%) (P < 0.05). Conclusions: Palonosetron combined with dexamethasone was more effective in preventing PONV compared to dexamethasone alone in women receiving IV-PCA using fentanyl.

Background: We compared upper- and lower-body forced-air blankets in terms of their ability to prevent perioperative hypothermia, defined as a reduction in body temperature to < 36.0°C, during the perioperative period in patients undergoing spine surgery in the prone position.Methods: In total, 120 patients scheduled for elective spine surgery under general anesthesia were divided into an upper-warming group (n = 60) and a lower-warming group (n = 60). After inducing anesthesia and preparing the patient for surgery, including prone positioning, the upper and lower bodies of the patients in the upper- and lower-warming groups, respectively, were warmed using a forced-air warmer with specified upper and lower blankets. Body temperature was measured using a tympanic membrane thermometer during the pre- and post-operative periods and using a nasopharyngeal temperature probe during the intraoperative period. Patients were evaluated in terms of shivering, thermal comfort, and satisfaction in the post-anesthesia care unit (PACU).Results: The incidence of intraoperative and postoperative hypothermia was lower in the upper-warming group than in the lower-warming group ([55.2% vs. 75.9%, P = 0.019] and [21.4% vs. 49.1%, P = 0.002]). Perioperative body temperature was higher in the upper-warming group (P < 0.001). However, intraoperative blood loss, postoperative thermal comfort scale and shivering scores, patient satisfaction, and PACU duration were similar in the two groups.Conclusions: The upper-body blanket was more effective than the lower-body blanket for preventing perioperative hypothermia in patients who underwent spine surgery in the prone position.

Objective: Patient’ desire of transfusion free surgery has been increasing due to blood transfusion risks. We analyzed the perioperative parameters and perioperative management of transfusion free surgical treatment in Soonchunhyang University Seoul Hospital. Methods: Operation quantity and blood unstoring count from blood bank between 2000 and 2012 were collected from chronological records. Perioperative parameters including preoperative hemoglobin level, postoperative hemoglobin level, and lowest hemoglobin level were collected from medical records. Perioperative blood management such as acute normovolemic hemodilution, intraoperative blood cell salvage, or hematinic agents and complication were assessed. Results: A total of 3,088 patients underwent transfusion free surgery at Soonchunhyang University Seoul Hospital between 2000 and 2012. Postoperative hemoglobin level <5.0 g/dL were 33 patients. Four patients expired at postoperative period with serious perioperative complications. Average of expired patient’s hemoglobin was 3.22 g/dL and overall mortality was 0.12%. Operation was increased as years go by. The amount of blood use bank wasn’t increased in general patients with transfusion. Conclusion: Careful perioperative blood management for transfusion free surgical treatment was responsible for safety and results in good clinical outcomes. Overall transfusion rate was decreased in spite of increasing operation quantity.

유재화,Ok Si Young,김상호,정지원,박선영,김문규,조호범,You Gyu Wan 대한마취통증의학회 2020 Anesthesia and pain medicine Vol.15 No.3

Background: This study aimed to evaluate the efficacy of 10-min pre-warming in preventing inadvertent perioperative hypothermia, which is defined as a reduction in body temperature to less than 36.0℃ during the perioperative period in intraoperative warming patients. Methods: In this prospective randomized study, 60 patients scheduled for elective surgery under general anesthesia lasting less than 120 min were divided into two groups: the 10-min pre-warming group (n = 30) and the control group (n = 30). Patients in the 10-min pre-warming group were pre-warmed for 10 min in the pre-anesthetic area using a forced-air warmer set at 47ºC. Intraoperatively, we warmed all patients with a forced-air warmer. Body temperature was measured using a tympanic membrane thermometer pre- or postoperatively and a nasopharyngeal temperature probe intraoperatively. Patients were evaluated on the shivering and thermal comfort scale in the pre-anesthetic area and post-anesthesia care unit. Results: The incidences of intraoperative hypothermia and postoperative hypothermia were similar in both groups (10.7% vs. 28.6%, P = 0.177; 10.7% vs. 10.7%, P = 1.000 respectively). Body temperature was higher in the 10-min pre-warming group (P = 0.003). Thermal comfort during the pre-warming period was higher in the 10-min pre-warming group (P < 0.001). However, postoperative thermal comfort and shivering grades of both groups were similar.Conclusions: Ten minutes of pre-warming has no additional effect on the prevention of inadvertent perioperative hypothermia in intraoperative warming patients.

유재화,김순임,조아나,이성진,선해정,조호범,이동련 대한마취통증의학회 2015 Korean Journal of Anesthesiology Vol.68 No.5

Background: The purpose of this study was to evaluate the effect of intraoperative dexmedetomidine sedation on patient’s and surgeon’s satisfaction during retinal surgery under sub-tenon’s anesthesia. Methods: Forty-four patients scheduled for elective retinal surgery under sub-tenon’s anesthesia were enrolled in this randomized controlled trial. The patients were divided into Dexmedetomidine (n = 22) and Control (n = 22) groups. Intravenous dexmedetomidine or 0.9% saline via infusion pump were administered continuously to the dexmedetomidine or control group, respectively. Ramsay sedation scale with a target level of 3–4 was used to assess adequacy of sedation. Perioperative pain, hemodynamic and respiratory data were collected, while satisfaction from patients and surgeon were assessed post-surgery using a 5-point satisfaction scale. Results: Patient and surgeon satisfaction was higher in the dexmedetomidine group (P < 0.001, P = 0.002, respectively). The pain associated with sub-tenon’s anesthesia and peripheral vitrectomy was lesser in the dexmedetomidine group than in the control group (P = 0.020). There was significant reduction of heart rate in the dexmedetomidine group (P = 0.001), but only one patient needed treatment with atropine. There was no respiratory effect on both groups. Conclusions: Dexmedetomidine sedation during retinal surgery improved satisfaction from both patient and surgeon without respiratory complication. It is a safe and preferable choice of sedation for retinal surgery.

Background: The aim of this study was to evaluate aprepitant in combination with palonosetron as compared to palonosetron alone for the prevention of postoperative nausea and vomiting (PONV) in female patients receiving fentanyl- based intravenous patient-controlled analgesia (IV-PCA). Methods: In this randomized single-blinded study, 100 female patients scheduled for elective surgery under general anesthesia were randomized to two groups: Group AP (80 mg aprepitant plus 0.075 mg palonosetron, n = 50) and Group P (0.075 mg palonosetron, n = 50). The patients in group AP received 80 mg aprepitant per oral 1–3 h before surgery, while all patients received 0.075 mg palonosetron after induction of standardized anesthesia. All patients had postoperative access to fentanyl-based IV-PCA. The incidence of nausea and vomiting, use of rescue medication, and severity of nausea were evaluated at 6 and 24 h after surgery. Results: The incidence of nausea (54%) and vomiting (2%) in group AP did not differ significantly from that in group P (48% and 14%, respectively) during the first 24 h after surgery (P > 0.05). Patient requirements for rescue medication in group AP (29%) were similar to those in group P (32%) at 24 h after surgery (P > 0.05). There was no difference between the groups in severity of nausea during the first 24 h after surgery (P > 0.05). Conclusions: Aprepitant combined with palonosetron did not reduce the incidence of PONV as compared to palonosetron alone within 24 h of surgery in women receiving fentanyl-based IV-PCA.

Objective: Recently, the cases about successful regional anesthesia using combined superficial cervical plexus block and interscalene brachial plexus block for clavicle surgery have been reported. The aim of this study was to compare regional anesthesia using combined superficial cervical plexus block and interscalene brachial plexus block with general anesthesia. Methods: In this prospective randomized study, 26 patients scheduled for elective clavicle surgery were divided into two groups: the first group was general anesthesia group (GA group, n=13) and the second group for peripheral nerve block group (PNB group, n=13). Standardized general anesthesia was done to the patients assigned to the GA group and ultrasonography-guided combined superficial cervical plexus block and interscalene brachial plexus block was done to the patients assigned to the PNB group. Postoperative sedation scale was assessed at post-anesthesia care unit, and pain scale using 10-cm Visual Analog Scale (VAS) was assessed at immediate postoperative, 30 minutes, 1 hour, 6 hours, and 24 hours. Patients needed additional analgesics, and time for first analgesic demand and duration from surgery to discharge was recorded. Results: The pain VAS scales were less in PNB group than GA group from immediate postoperative time to 6 hours. The patients’ immediate postoperative sedation scale less than 4 were significantly less in PNS group than GA group. The duration from surgery to discharge was shorter in PNS group than GA group. Conclusion: Regional anesthesia using combined superficial cervical plexus block and interscalene brachial plexus block is a successful alternative to general anesthesia for clavicle surgery.
