조윤이,김홍순,곽현정,장영진,윤순영 대한마취통증의학회 2013 Korean Journal of Anesthesiology Vol.65 No.1

Background: Perioperative hypothermia can develop easily during shoulder arthroscopy, because cold irrigation can directly influence core body temperature. The authors investigated whether active warming and humidification of inspired gases reduces falls in core body temperature and allows redistribution of body heat in patients undergoing arthroscopic shoulder surgery under general anesthesia. Methods: Patients scheduled for arthroscopic shoulder surgery were randomly assigned to receive either room temperature inspired gases using a conventional respiratory circuit (the control group, n = 20) or inspired gases humidified and heated using a humidified and electrically heated circuit (HHC) (the heated group, n = 20). Results: Core temperatures were significantly lower in both groups from 30 min after anesthesia induction, but were significantly higher in the heated group than in the control group from 75 to 120 min after anesthesia induction. Conclusions: In this study the use of a humidified and electrically heated circuit did not prevent core temperature falling during arthroscopic shoulder surgery, but it was found to decrease reductions in core temperature from 75 min after anesthesia induction.

조윤용(趙允庸),이혜진(李?珍),황성욱(黃盛郁) 한국지방정부학회 2015 지방정부연구 Vol.18 No.4

이 연구는 최근 빠른 속도로 다문화사회화 되어가고 있는 한국사회의 외국인주민의 소통권을 보장할 수 있는 정책적 함의를 찾기 위한 연구이다. 다문화주의 논의와 관련하여 최근 주목받기 시작한 소통권(communication rights)은 인간이 가져야할 기본적이고도 보편적인 권리이며 소통권의 보장을 통해서 인간의 존엄성과 평등권을 누릴 수 있고, 나아가 다른 기본권을 보호하고 구현할 수 있다. 다문화시대의 소통권에 대한 학문적 논의의 필요성을 인지하면서, 이 연구는 모든 사회구성원들이 누려야 할 소통권의 보장을 위해 어떠한 정책적 대응이 수반되어야 하는지 알아보고자 한다. 구체적으로, 사회구성원이 마땅히 누려야할 기본권인 소통권에 대한 개념을 정립하고 다문화사회에서의 외국인주민의 소통권 증진을 위한 지방자치단체 차원의 정책 방향을 모색하고자 한다. 이에 따라, 부산시 외국인주민 관련 전문가 8명을 대상으로 포커스그룹인터뷰를 실시하고, 인터뷰를 통해 외국인주민의 소통권 증진을 위해 어떠한 정책적 전략을 수립해야 하는지에 대한 함의를 제시할 것이다. 외국인주민의 소통권 증진을 위한 학문적 논의가 드문 상황에서 이 연구는 다문화정책, 그 중에서 외국인주민의 소통과 관련해서 지방정부차원에서의 지원 정책을 추진하는데 학술적, 실무적 의의를 가질 것이라고 예상한다. As foreign residents’ population has rapidly risen since the early 1990s, South Kora has become a post-national, multicultural society. For a better transition to the multicultural society, efficiently coordinated public communications with foreign residents are essential. Given the importance of public communication with foreign residents, there also has been much of discussion regarding communication rights for foreign residents. Communication rights represent universal and fundamental human rights that everyone in the democratic society should be entitled. Communication rights enable individuals to strengthen human dignity and equality. Given the importance of communication rights in the multicultural society, this study conducted a focus group interview with 8 experts to discuss local governments’ communicational directions to enhance communication rights for foreign residents. With the focus group interview, this study aimed to 1) analyze a current public communication system in the local government, and 2) discuss the possible solutions to strengthen foreign residents’ communication rights. Based on the results, theoretical and practical implications were discussed.

Anesthetic management of HELLP syndrome complicating primary antiphospholipid syndrome -A case report-

조윤이,이경천,김홍순,배현경,장영진 대한마취통증의학회 2012 Korean Journal of Anesthesiology Vol.62 No.6

Antiphospholipid syndrome (APS) is defined as an autoimmune disorder characterized by recurrent thrombosis or obstetrical morbidity. A 29-year-old woman who was diagnosed with APS underwent emergency cesarean delivery at 23 weeks’ gestation. She had a seizure attack and her laboratory findings were: AST/ALT 1459/1108 IU/L, LDH 1424 IU/L, 30% hematocrit, a platelet count of 43 × 103/ml and urine protein (4+). We describe the anesthetic experience of catastrophic HELLP syndrome with antiphospholipid syndrome and we review the relevant literature.

Sedation Strategies for Procedures Outside the Operating Room

조윤이,곽현정 연세대학교의과대학 2019 Yonsei medical journal Vol.60 No.6

With the rapid development of diagnostic and therapeutic procedures performed outside the operating room (OR), the need forappropriate sedation care has emerged in importance to ensure the safety and comfort of patients and clinicians. The preparationand administration of sedatives and sedation care outside the OR require careful attention, proper monitoring systems, and clinicallyuseful sedation guidelines. This literature review addresses proper monitoring and selection of sedatives for diagnostic andinterventional procedures outside the OR. As the depth of sedation increases, respiratory depression and cardiovascular suppressionbecome serious, necessitating careful surveillance using appropriate monitoring equipment.

Prediction of early postoperative desaturation in extreme older patients after spinal anesthesia for femur fracture surgery: a retrospective analysis

조윤이,박춘곤,이지연,권선구,곽현정 대한마취통증의학회 2019 Korean Journal of Anesthesiology Vol.72 No.6

Background: Postoperative desaturation in older individuals is rarely addressed in the literature. The objective of this retrospective study was to investigate whether a preoperative spirometric test and arterial blood gas analysis (ABGA) might predict postoperative desaturation after spinal anesthesia in extreme older patients. Methods: The medical records of 399 patients (age ≥ 80 yrs) who were administered spinal anesthesia for a femur neck fracture surgery were retrospectively reviewed. Early postoperative desaturation was defined as a reduction of oxygen saturation (SpO2) below 90% within 3 days of surgery, despite O2 supply via a nasal prong. Binary logistic regression analysis was used to identify predictors of early postoperative desaturation. Results: The incidence of postoperative desaturation was 12.5%. Major morbidity rate was significantly higher in the desaturation group (n = 50) than that in the non-desaturation group (n = 349) (14% vs. 3.2%, P = 0.001) with more frequent postoperative stays in the intensive care unit (22% vs. 12%, P = 0.004). In a binary logistic regression analysis, preoperative ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2 ratio) (OR, 0.972; 95% CI 0.952–0.993; P = 0.010) and history of cardiovascular disease (OR, 2.127; 95% CI 1.004–4.507; P = 0.049) predicted postoperative desaturation. Conclusions: Preoperative PaO2/FiO2 ratio, but not preoperative spirometry, was predictive of the postoperative desaturation in older patients after being administered spinal anesthesia for femur fracture surgery. Based on our results, preoperative ABGA may be helpful in predicting early postoperative desaturation in these patients.

조윤이,Ji Hyun Yoo,Hyun Joo Kim,길혜금 대한마취통증의학회 2011 Korean Journal of Anesthesiology Vol.61 No.3

Background: Epidurally administered dexamethasone may reduce the incidence and severity of postoperative pain. We investigated whether postoperative pain could be alleviated by preoperative or postoperative epidural dexamethasone administration in patients undergoing major abdominal surgery. Methods: Ninety patients (age 30-77 with American Society of Anesthesiologists physical status I and II) undergoing radical subtotal gastrectomy were randomly allocated to three groups using computer generated randomization. In all groups, 10 ml of 0.25% ropivacaine was injected epidurally before the start and at the end of the operation. In Group I, a bolus ropivacaine epidural without dexamethasone was administered. In Group II, dexamethasone (5 mg) was added to the ropivacaine bolus epidural before the start of operation. In Group III, the same amount of dexamethasone was given with the ropivacaine epidural at the end of operation. Effort and resting VAS, the use of rescue analgesics and any complications noted during the procedure were evaluated. Results: VAS and requirements of rescue analgesics were significantly lower in Groups II and III when compared to Group I. There were no difference in the incidence of nausea and vomiting between groups, but an itching sensation was frequent in Group III. Conclusions: The administration of 5 mg of dexamethasone epidurallly, before or after operation, could reduce the pain and analgesic requirement after radical subtotal gastrectomy.
