        Aprepitant prophylaxis effectively reduces preventing postoperative nausea and vomiting in patients receiving opioid based intravenous patient-controlled analgesia

        여귀은,이미경,김희주,공명훈,손효정,오한별 대한마취통증의학회 2018 Anesthesia and pain medicine Vol.13 No.3

        Background: Aprepitant is effective in prevention of chemotherapy-induced nausea and vomiting, when administrated with other antiemetics. We compared the effectiveness of aprepitant to ondansetron for prevention of post-operative nausea and vomiting (PONV) in patients who received a patient-controlled analgesia (PCA) containing opioids. Methods: 198 patients were randomized into two groups. The treatment group was received an aprepitant, 80 mg, and the control group received a placebo. General anesthesia with inhalational anesthetics–N2O was performed, and PCA was supplied, which contained opioids-NSAIDs-ondansetron. The primary end-point was the incidence of PONV for postoperative 48 hours, and the secondary end-point was the changes in the relationship between PONV incidence and risk factors. Results: PONV incidence in the treatment group was lower than in the control group (18.6% [95% CI: 10.8–26.3], 33.3% [95% CI: 23.6–43.1], respectively, P = 0.021). Relative risk of PONV in the control group was 1.80 (95% CI: 1.08–3.00, P = 0.010). PONV scores peaked at around postoperative 6 hours, then gradually decreased in the control group but not in the treatment group, which showed lower values than the control group (P = 0.001), and no changing patterns were observed (P < 0.001). Risk factors analyzed were sex, surgery type, history of motion sickness or PONV, and smoking habits. Their effects of all risk factors except sex were abolished in the treatment group. Conclusions: Prophylactic aprepitant with ondansetron was more effective than ondansetron- only regimen in preventing PONV after volatile anesthesia with opioid-containing PCA. Aprepitant abolished the effects of most of risk factors, so it could be efficacious in a high-risk PONV group.

        Intraocular Hemorrhage After Transoral Endoscopic Thyroidectomy Vestibular Approach

        김준형,여귀은,김태훈,홍용태 대한이비인후과학회 2022 대한이비인후과학회지 두경부외과학 Vol.65 No.6

        Transoral endoscopic thyroid surgery vestibular approach (TOETVA) is now widely per- formed globally with good cosmetic outcomes. However, there are complications related to this approach which surgeons should be aware of. We report here a 41-year-old female patient who had an unusual ocular complication after total thyroidectomy via TOETVA. She was di- agnosed with papillary thyroid carcinoma and received total thyroidectomy via TOETVA. She complained of floating particles in her right eye immediately after the operation. Fundus ex- amination revealed intraocular hemorrhage in her right eye. At one-month follow-up, all of the intraocular hemorrhage was improved by fundus examination, resolving her chief complaint. Surgeons and anesthesiologists should be aware of increased intracranial pressure during the TOETVA and possible ocular complications after the surgery, although they are rare.

        The prevalence and clinical significance of transitional vertebrae: a radiologic investigation using whole spine spiral three-dimensional computed tomographic images

        두아람,이정우,여귀은,이근형,김예슬,문주환,한영진,손지선 대한마취통증의학회 2020 Anesthesia and pain medicine Vol.15 No.1

        Background: Errors in counting spinal segments are common during interventional procedures when there are transitional vertebrae. In this study, we investigated the prevalence of the transitional vertebrae including thoracolumbar transitional vertebra (TLTV) and lumbosacral transitional vertebrae (LSTV). The relationship between the existence of TLTV and abnormal rib count or the existence of LSTV were also evaluated. Methods: The vertebral levels were counted craniocaudally, starting from C1, based on the assumption of 7 cervical, 12 thoracic, and 5 lumbar vertebrae, using whole spine spiral three-dimensional computed tomographic images. The 20th and 25th vertebrae were defined as L1 and S1, respectively. Results: In total, 150 patients had TLTV, with a prevalence of 11.2% (150/1,340). LSTV was observed in 111 of 1,340 cases (8.3%). Sacralization was observed in 68 of 1,340 cases (5.1%) and lumbarization in 43 of 1,340 cases (3.2%). There was a significant relationship between the existence of TLTV and the abnormal rib count (odds ratio [OR]: 117.26, 95% confidence interval [95% CI]: 60.77–226.27; P < 0.001) and LSTV (OR: 7.38, 95% CI: 3.99–13.63; P < 0.001). Conclusions: Our study results suggest that patients with TLTV are more likely to have an abnormal rib count or LSTV. If a TLTV or LSTV is seen on the fluoroscopic image, a whole spine image is necessary to permit accurate numbering of the lumbar vertebra.

        Delayed diagnosis of postintubation tracheal laceration in a patient who underwent septorhinoplasty including osteotomy - A case report -

        손효정,문수진,고진우,김태웅,이현수,김혜진,여귀은,이동규,최윤지 대한마취통증의학회 2018 Anesthesia and pain medicine Vol.13 No.1

        Iatrogenic postintubation tracheal injury is a rare but potentially fatal complication associated with anesthesia. However, as signs of tracheal injury including subcutaneous emphysema, pneumomediastinum, pneumothorax, and respiratory distress may also be related to surgical technique, diagnosis may be confused and treatment of tracheal injury can be delayed. We report a case of postintubation tracheal laceration, whose diagnosis was delayed because of symptoms were confused with subcutaneous emphysema after septorhinoplasty including osteotomy. As symptoms deteriorated in spite of conventional management, patient underwent evaluation to determine other causes and eventually postintubation tracheal injury was detected. Therefore, even if there is no problem during tracheal intubation, it is necessary to consider postintubation tracheal injury in patients with subcutaneous emphysema that worsens despite appropriate treatment after septorhinoplasty including osteotomy.

        Isoflurane's Effect on Intraoperative Systolic Left Ventricular Performance in Cardiac Valve Surgery Patients

        김주덕,손일순,권원경,성태윤,Hanafi Sidik,김가람,강현,방지연,여귀은,이동규,김태엽 대한의학회 2018 Journal of Korean medical science Vol.33 No.4

        Background: Isoflurane, a common anesthetic for cardiac surgery, reduced myocardial contractility in many experimental studies, few studies have determined isoflurane's direct impact on the left ventricular (LV) contractile function during cardiac surgery. We determined whether isoflurane dose-dependently reduces the peak systolic velocity of the lateral mitral annulus in tissue Doppler imaging (S′) in patients undergoing cardiac surgery. Methods: During isoflurane-supplemented remifentanil-based anesthesia for patients undergoing cardiac surgery with preoperative LV ejection fraction greater than 50% (n = 20), we analyzed the changes of S′ at each isoflurane dose increment (1.0, 1.5, and 2.0 minimum alveolar concentration [MAC]: T1, T2, and T3, respectively) with a fixed remifentanil dosage (1.0 μg/min/kg) by using transesophageal echocardiography. Results: Mean S′ values (95% confidence interval [CI]) at T1, T2, and T3 were 10.5 (8.8–12.2), 9.5 (8.3–10.8), and 8.4 (7.3–9.5) cm/s, respectively (P < 0.001 in multivariate analysis of variance test). Their mean differences at T1 vs. T2, T2 vs. T3, and T1 vs. T3 were −1.0 (−1.6, −0.3), −1.1 (−1.7, −0.6), and −2.1 (−3.1, −1.1) cm/s, respectively. Phenylephrine infusion rates were significantly increased (0.26, 0.22, and 0.47 μg/kg/min at T1, T2, and T3, respectively, P < 0.001). Conclusion: Isoflurane increments (1.0–2.0 MAC) dose-dependently reduced LV systolic long- axis performance during cardiac surgeries with a preserved preoperative systolic function.
