Simplified equation for determining proper depth of peripherally inserted central catheter in relation to anatomical landmarks / 대한마취과학회지

BACKGROUND: The aim of this study was to develop a formula guiding the peripherally inserted central catheter (PICC) tip placement based on anatomical landmarks such as the upper arm, clavicle, and sternum as well as the patient’s height, weight, and body mass index. METHODS: Fifty-five patients who were scheduled to have PICCs were included in the study. We measured four distances along the passage of the PICC, which were as follows; the tip of the third finger to the middle of the elbow crease (Distance A), the middle of the elbow crease to the acromion process (Distance B), the acromion process to the sternal head of the clavicle (Distance C), and the sternal head of the clavicle to the end of the xiphoid process (Distance D). The lengths from the elbow creases to their carina bifurcations as determined by fluoroscopy during PICC insertions were recorded and used as reference. RESULTS: The formula for determining PICC depth based on the four distances was determined by regression analysis. The optimal formula was determined to be 25.3 + 0.5 × (Distance C) + 0.6 × (Distance D) which yielded an R2 value of 0.3. CONCLUSIONS: The formula proposed for proper depth of the adult, 25.0 + 0.5 × (clavicle length) + 0.6 × (sternum length) for PICC insertion can be used to place the tip at the carina bifurcation level. The distance from elbow crease to catheter insertion point should be added to the length generated by this formula.

Brugada Syndrome Patient Undertaken Brachial Plexus Block / 이화의대지

Brugada syndrome is an arrhythmic syndrome characterized by right bundle branch block, ST segment elevation in the precordial lead (V1-V3), and sudden death caused by ventricular fibrillation, which is not effectively prevented by anti-arrhythmic drug therapy. We are reporting a 30-year-old male patient with Brugada syndrome who got an exploratory laparotomy and a tenorrhaphy due to stab wound which was managed with general anesthesia and brachial plexus block without any complications.

Pulmonary aspiration during anesthetic induction in a patient with laparoscopic adjustable gastric band: A case report

Recently, the number of laparoscopic adjustable gastric banding surgery is increasing as is the number of patients with morbid obesity rapidly. However, no anesthetic management including preoperative fasting strategy for patients with laparoscopic adjustable gastric banding exists. Hereby, we report a case of a 22-year-old woman with laparoscopic adjustable gastric banding who suffered pulmonary aspiration during the anesthetic induction for appendectomy, despite a preoperative fasting period longer than 14 h. This case strongly suggests that guidelines for anesthetic management including the appropriate fasting period for patients with laparoscopic adjustable gastric banding are desperately required.
