Successful Treatment of Rectus Femoris Calcification with Ultrasound-guided Injection: A Case Report

Painful periarticular calcification most commonly occurs within the rotator cuff of the shoulder and rarely around the elbow, hip, foot, and neck. As acute inflammatory reaction develops, severe pain, exquisite tenderness, local swelling, and limitation of motion with pain occur. In case of calcific tendinitis of the shoulder, it can be easily diagnosed according to the symptoms and with x-ray. However, in lesions of the hip, as it is a rare location and usually involves pain in the posterolateral aspect of the thigh, which can simulate radicular pain from a lumbar intervertebral disc, it could be difficult to diagnose. Hence, physicians usually focus on lumbar lesions; therefore, misdiagnosis is common and leads to a delayed management. Here, we report the case of a 30-year-old female patient with calcific tendinitis of the rectus femoris that was successfully managed with ultrasound-guided steroid injection. This study offers knowledge about the rectus femoris calcification.

Optimal dosages of propofol and remifentanil for minimizing hemodynamic changes during laryngeal microscopic surgery / 대한마취과학회지

BACKGROUND: Laryngeal microscopic surgery (LMS) is stressful to the patient due to intubation and suspension laryngoscopy. The aim of this study was to determine the optimal dosages of propofol and remifentanil for minimizing hemodynamic changes during LMS. METHODS: Eighty outpatients undergoing LMS were randomly divided into four groups. In all patients, endotracheal intubation was done with an effect-site concentration of propofol at 3 or 4microgram/ml. Group I (propofol 3microgram/ml) and II (propofol 4microgram/ml) patients received remifentanil 0.5microgram/kg and an infusion at 0.1microgram/kg/min. Group III (propofol 3microgram/ml) and IV (propofol 4microgram/ml) patients received remifentanil 1.0microgram/kg and an infusion at 0.2microgram/kg/min. Hemodynamic changes and bispectral index (BIS) values during intubation and suspension laryngoscopy were compared among the groups. In addition, extubation time, emergence time, and state of recovery (Steward score) were compared. RESULTS: After intubation and suspension laryngoscopy, the mean arterial pressure (MAP) was significantly lower than baseline values in groups II and IV (P < 0.05). After suspension laryngoscopy, the heart rate (HR) was significantly lower than baseline value in group II (P < 0.05). Extubation time was significantly shorter in groups I, II, and III compared to group IV, and the time for responding to verbal commands was significantly shorter in groups I and II compared to group IV (P < 0.05). The incidence of hypotension was higher in group IV than in the other groups (P < 0.05). CONCLUSIONS: The results suggest that an effect-site concentration of propofol at 4microgram/ml with remifentanil 0.5microgram/kg and infusion of 0.1microgram/kg/min provide proper anesthesia with minimal hemodynamic changes during LMS.

Comparison of Sevoflurane-N2O and Propofol-N2O Anesthesia for Laryngeal Microscopic Surgery / 대한마취과학회지

BACKGROUND: Laryngeal microscopic surgery is stressful as a result of the intubation and suspension laryngoscopy during the short operation time. Therefore, the objectives of the anesthesiologist are to maintain sufficient anesthetic depth, promote rapid awakening, and return the protective airway reflexes. This study compared the hemodynamic responses and recovery patterns between propofol-N2O and sevoflurane-N2O anesthesia. METHODS: Sixty outpatients undergoing laryngeal microscopic surgery were randomly divided into three groups: Endotracheal intubation with the effect-site concentration of propofol fixed at 3 ug/ml (Group P3), 4 ug/ml (Group P4) or endotracheal intubation with sevoflurane anesthesia (Group S). In all groups, the anesthesia was supplemented with up to 50% of N2O. The hemodynamic responses during intubation and suspension laryngoscopy were compared. In addition, extubation time, emergence time and the state of recovery (Steward score) were compared. RESULTS: After intubation and suspension laryngoscopy, the mean arterial pressure was significantly higher in Group S than in Groups P3 and P4 (P < 0.05). The heart rate was significantly higher in Group S than in the Group P4 (P < 0.05). The extubation times were not significantly different. However, the time for responding to a verbal command was significantly faster in Groups P3 (7.8 +/- 2.3 min) and P4 (8.8 +/- 1.9 min) than in Group S (10.6 +/- 1.8 min). The Steward score 1 min after extubation was significantly higher in Group S (P < 0.05). CONCLUSIONS: Propofol-N2O anesthesia can be useful in laryngeal microscopic surgery.
