Clinical Experience of Symptomatic Sacral Perineural Cyst

정기태,이현영,임경준 대한통증학회 2012 The Korean Journal of Pain Vol.25 No.3

Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient’s symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst.

Successful application of high-flow nasal cannula in a patient with postoperative respiratory disturbance after bilateral sagittal split ramus osteotomy surgery - A case report -

정기태,지인국,김상훈 대한마취통증의학회 2018 Anesthesia and pain medicine Vol.13 No.3

Bilateral sagittal split ramus osteotomy (BSSRO) is generally indicated for mandibular setback, to improve occlusion, masticatory function, and aesthetics by altering the mandibular position. However, BSSRO narrows the pharyngeal airway and increases airway resistance, resulting in postoperative respiratory disturbances during emergence from anesthesia. Oxygen delivery system via high-flow nasal cannula (HFNC) has been known to improve airway patency and oxygenation via low-level positive pressure as well as reduce the respiratory load. We report a case of postoperative respiratory disturbance, following a large mandibular setback, despite nasotracheal extubation in the fully awake patient. Respiratory disturbance was successfully controlled after oxygen delivery via HFNC until self-respiration was completely restored. Therefore, the use of HFNC may facilitate the control of postoperative respiratory disturbances induced by anatomical changes in upper airway after BSSRO surgery.

Palonosetron for postoperative nausea and vomiting after gynecological laparoscopic surgery: Comparison of its effect on sevoflurane vs desflurane vs total intravenous anesthesia

정기태,임경준,배효성,조동원,이현영 대한마취통증의학회 2014 Anesthesia and pain medicine Vol.9 No.3

Background: Postoperative nausea and vomiting (PONV) is oneof the most common complications after gynecological laparoscopicsurgery and it appears more frequently after use of inhalationanesthetics than total intravenous anesthesia (TIVA). Palonosetronwas introduced as a new-generation potent antiemetic agent, whichmay reduce PONV more effectively than previous drugs. The aimof this study was to evaluate whether palonosetron could preventPONV after gynecological laparoscopic surgery, regardless of theanesthetic technique employed. Methods: Seventy-three patients scheduled for gynecologicallaparoscopic surgery were randomly assigned into 3 groupsaccording to the anesthetic agent employed (group 1: inhalationanesthesia with desflurane, group 2: inhalation anesthesia withsevoflurane, group 3: total intravenous anesthesia with propofol andremifentanil). Palonosetron 0.075 mg was administered intravenouslybefore the induction. Opioids were not used for postoperativepain control. The incidences of nausea, vomiting and side effectswere recorded from 2 hr upto 48 hr, postoperatively. Results: There were no significant differences in the incidence ofPONV, severity of nausea, and the use of rescue antiemetics amongthe groups, throughout the observation. No differences wereobserved in the adverse side effects among the groups. Conclusions: Palonosetron decreased the incidence of PONVafter gynecological laparoscopic surgery to a similar level,regardless of the anesthetic technique.

Clinical evaluation of a newly designed fluid warming kit on fluid warming and hypothermia during spinal surgery

정기태,김상훈,소금영,소형진,심수빈 대한마취통증의학회 2015 Korean Journal of Anesthesiology Vol.68 No.5

Background: The Mega Acer Kit® (MAK) is a newly designed heated and humidified breathing circuit that warms fluid passing through the circuit lumen. In this study, we investigated the system’s efficacy for the perioperative prevention of hypothermia and fluid warming. Methods: Ninety patients undergoing spinal surgery were enrolled in this study and randomly assigned to 3 groups based on the fluid warming device used: no fluid warming system (Group C, n = 30), via a Standard Ranger (Group R, n = 30), or via the MAK (Group M, n = 30). Distal esophageal temperatures (Teso) and infusion fluid temperature (TF) were recorded at 15 min intervals for duration of 180 min during surgery. If Teso was < 35.0oC, a forced-air convective warming device was used. Results: Final Teso values were 34.8 ± 0.3oC, 35.1 ± 0.1oC, and 35.8 ± 0.3oC in groups C, R, and M, respectively (P < 0.01). Teso was significantly higher in group M when compared with that in groups C and R throughout the study period (P < 0.05). The number of patients requiring a forced-air convective warming device was significantly lower in group M (n = 0) when compared with that in groups R (n = 17) and C (n = 30) (P < 0.05). The final infusion fluid temperature was higher in group M when compared with that in groups C and R throughout the study period (35.4 ± 1.0 vs. 23.0 ± 0.3 and 32.8 ± 0.6oC; P < 0.01). Conclusions: The MAK is more effective for preventing hypothermia and for warming fluid than the Standard Ranger.

Mushroom jellies using extracts of Garnoderma lucidum, Lentinus edodes, Pacilomyces ten tenuipes and Cordyceps militaris were prepared, and Investigated the colors, texture and sensory characteristics of mushroom jellies. G. lucidum jelly mixed 85% mushroom, 10% jujube(Zizyphus jujuba Miller) and 5% hwanggi (Astragaslus membranaceus) extract, L. edodes jelly mixed 80% mushroom, 10% jujube, 5% gamcho( Glycyrrhiza uralensis) and 5% omija (Schizandrae chinensis Ruprecht) extract. and P. tenuipes and C. militaris jelly mixed 85% mushroom. 10% jujube and 5% gamcho extract were most effective in overall acceptability. The Jellying ability of carrageenan was better than other jelling agents. According to increase carrageenan content, color of mushroom Jellies were not effect. however hardness, gumminess and chewiness were increased. Sensory evaluation of mushroom Jellies were most preferable at the 0.6% carrageenan content.

Updated review of resistance to neuromuscular blocking agents

정기태,안태훈 대한마취통증의학회 2018 Anesthesia and pain medicine Vol.13 No.2

Since neuromuscular blocking agents (NMBAs) were introduced to the surgical field, they have become almost mandatory for the induction and maintenance of anesthesia. However, resistance to NMBAs can develop in certain pathological states, such as central nerve injury, burns, and critical illnesses. During such pathological processes, quantitative and qualitative changes occur in the physiology of acetylcholine and the acetylcholine receptor (AChR) at the neuromuscular junction. Up-regulation of AChR leads to changes in the pharmacokinetics and pharmacodynamics of NMBA. As NMBA resistance may result in problems during anesthesia, it is of utmost importance to understand the mechanisms of NMBA resistance and their associations with pathological status to maintain adequate neuromuscular relaxation. This review presents the current knowledge of pharmacokinetic and pharmacodynamic changes and pathological status associated with NMBA resistance.

Effect of gastric decompression on postoperative vomiting in pediatric patients undergoing strabismus surgery: a randomized controlled study

정기태,김세훈,김동준,김상훈,안태훈 대한마취통증의학회 2020 Anesthesia and pain medicine Vol.15 No.1

Background: Postoperative vomiting (POV) is one of the most serious complications in pediatric patients undergoing strabismus surgery. This study was conducted to test the hypothesis that gastric decompression (GD) could prevent POV caused by gastric distension after mask ventilation. Methods: A total of 60 pediatric patients (ASA PS I–II, aged one to 10 years) were randomly allocated to two groups; Group D (n = 30) and Group C (n = 30). Induction of anesthesia was performed with careful face mask ventilation with 100% O2 (3 L/min) and sevoflurane 3 vol% to limit airway pressure below 20 cmH2O. Endotracheal intubation was done after confirming adequate neuromuscular blockade. Then, the patients in Group D received GD, while patients in Group C did not. After the surgery, POV was assessed during the emergence from anesthesia in the operating room and postanesthetic care unit (30 min and 60 min). Results: During the emergence, POV was significantly decreased in Group D compared to Group C (Group D 3.3% vs. Group C 30.0%, P = 0.006). The odds ratio analysis showed a lower incidence of POV in Group D (odds ratio = 0.080; 95% confidence limit: 0.009–0.685) during the emergence period. There was no significant difference in the incidence of POV in the postanesthetic care unit (Group D 6.7% vs. Group C 4.3% at 30 min, P = 1.000; 0% in both groups at 60 min). Conclusions: GD reduced the incidence of POV in pediatric patients undergoing strabismus surgery during emergence.
