연구실 소개
이정만 교수의 연구실은 마취의학 분야에서 기도 관리와 기도 접근 기술의 안전성 및 편의성을 향상시키는 데 초점을 맞추고 있습니다. 특히 기관절개술, 기관내관 삽입 기술, 기도 폐색 예방을 위한 압박 기법(예: 크리코이드 압박, 부정맥 압박)의 효과를 체계적으로 평가하며, 환자의 불편을 줄이는 기구 설계(예: 편심형 쿠프 기관내관)와 정확한解부학적 구조 탐색 기법(예: 상향식 래리지 핸드쉐이크 기법) 개발에 주력하고 있습니다. 임상적 실용성과 환자 안전을 기반으로 한 혁신적인 기도 관리 전략을 모색하고 있습니다.

15Intubation using an endotracheal tube with a tapered cuff reduced the incidence and severity of postoperative sore throat and the incidence of hoarseness after surgery when compared with an endotracheal tube with a cylindrical cuff.
2 Laryngoscope, 131:2154-2159, 2021.
The nasal tip lifting maneuver helped to guide preformed nasal RAE tubes into the lower pathway during nasotracheal intubation.
Paratracheal pressure was noninferior to cricoid pressure with respect to the effect on glottic view during direct laryngoscopy.
The occlusion of the upper esophagus defined by inability to pass an esophageal stethoscope was more effective with cricoid pressure than with paratracheal pressure during videolaryngoscopy, although both cricoid and paratracheal pressures reduced the diameter of the esophagus on ultrasound in an anesthetized paralyzed state.
The modified upward laryngeal handshake technique that involved tracing the trachea and laryngeal structures upward from the sternal notch was more accurate in identifying the cricothyroid membrane than the conventional downward technique in anesthetized female patients.
Abstract Regrowth of decapitated seedlings of apple ( Malus domestica Borkh.) of a compact phenotype revealed stronger apical dominance and narrower branching angle than normal seedlings. Normal and compact seedlings were also found to differ in their phyllotaxy at lower nodes. Spraying with 2,3,5-triiodobenzoic acid (TIBA) before and/or after decapitation increased apparent apical dominance in compact seedlings; reduced shoot thickness in normal seedlings; and reduced shoot length and increased
In 41 healthy volunteers, we investigated the cross-sectional area (CSA) of the subclavian vein (SCV) in the following head positions: neutral and 30° head rotation toward the contralateral or ipsilateral sides. Significant differences were observed in the CSA of the SCV at 3 different head positions: contralateral 30° versus neutral, -0.05 cm (95% confidence interval, -0.08 to -0.03); contralateral 30° versus ipsilateral 30°, -0.15 cm (-0.19 to -0.12); neutral versus ipsilateral 30°, -0.10 cm (
Central obesity may be related to the spread of spinal anesthesia in female patients. Fifty-seven female patients undergoing spinal anesthesia were allocated to either the central obesity or noncentral obesity group. After induction of spinal anesthesia, maximal sensory blockade (primary outcome), time for maximal sensory block, maximum motor block, time to maximum motor block, time to L2 regression, and time to Bromage scale 0 were evaluated. Multiple linear regression analyses showed that maxi
For patients with HPS who require anesthesia for a procedure, HPV should be maintained to prevent worsening hypoxemia. Here, the case of a 9-yr-old girl who was scheduled for a living donor liver transplantation is presented. The patient suffered from end-stage liver disease with HPS due to biliary atresia, which contributed to the development of a diffuse pulmonary AVF. Consequently, anesthetic management of this patient involved two different types of pulmonary shunt. It is important to mainta
This research studied the application of samplers under three fixity conditions during sampling tube penetration and evaluated the quality of the retrieved samples. Original and portable types of oil-operated fixed-piston samplers with identical sampling tubes were employed at a site in the Nakdong River Delta. Suction, shear wave velocity and consolidation tests were conducted to assess sample quality. The soil fabric, including holes, nodules, roots and shells, rather than soil sensitivity (4
