RESUMO
BACKGROUND: Glycopyrrolate given as reversing agents of muscle relaxants has been reported to be effective in reducing postoperative catheter-related bladder discomfort (CRBD). However, it remains unclear whether glycopyrrolate as premedication is also effective. This study aims to investigate the effectiveness of glycopyrrolate as premedication on preventing CRBD in the post-anesthesia care unit (PACU). METHODS: Eighty-three patients who received elective ureteroscopic removal of ureteral stone were randomly assigned to the control (n = 43) or the glycopyrrolate group (n = 40). The glycopyrrolate group was treated with glycopyrrolate 0.3 mg as premedication while the control group received 0.9% saline 1.5 ml. The incidence and severity of CRBD and pain score using numerical rating scale (NRS) were measured in the PACU. RESULTS: The incidence of CRBD (26 of 40 patients vs. 41 of 43 patients, relative risk [RR] = 0.68, 95% Confidence interval [CI] = 0.53–0.86, P = 0.001) and the moderate to severe CRBD incidence (6 of 40 patients vs. 20 of 43 patients, RR = 0.32, 95% CI = 0.14–0.72, P = 0.002) were lower in the glycopyrrolate group than in the control group. Also, postoperative pain NRS score was found to be lower in the glycopyrrolate group (median = 1 [Q1 = 0, Q3 = 2]) compared to the control group (3 [1, 5], median difference = 1.00, 95% CI = 0.00–2.00, P = 0.002). CONCLUSIONS: The use of glycopyrrolate 0.3 mg as premedication in patients receiving ureteroscopic removal of ureteral stone reduced the incidence and severity of CRBD, and decreased postoperative pain in the PACU.

Several cases of the hiccups that occurred after interventional pain procedures have been previously reported. A 34-year-old man had suffered from persistent hiccups that started after epidural and trigger point injection of steroid. His hiccups were stopped during meals and sleep. Furthermore, hiccups did not occur after intravenous or intramuscular steroid injection due to eczema and bronchitis, and after interventional pain procedure that was performed under sedation with midazolam. Hence, we suspected that his hiccups had resulted from a psychogenic cause.

BACKGROUND: The stroke volume variation (SVV), based on lung-heart interaction during mechanical ventilation, is a useful dynamic parameter for fluid responsiveness. However, it is affected by many factors. The aim of this study was to evaluate the effects of SVV on Trendelenburg (T) and reverse Trendelenburg (RT) position and to further elaborate on the patterns of the SVV with position. METHODS: Forty-two patients undergoing elective surgery were enrolled in this study. Fifteen minutes after standardized induction of anesthesia with propofol, fentanyl, and rocuronium with volume controlled ventilation (tidal volume of 8 ml/kg of ideal body weight, inspiration : expiration ratio of 1 : 2, and respiratory rate of 10-13 breaths/min), the patients underwent posture changes as follows: supine, T position at slopes of operating table of -5degrees, -10degrees, and -15degrees, and RT position at slopes of operating table of 5degrees, 10degrees, and 15degrees. At each point, SVV, cardiac output (CO), peak airway pressure (PAP), mean blood pressure, and heart rate (HR) were recorded. RESULTS: The SVV was significant decreased with decreased slopes of operating table in T position, and increased with increased slopes of operating table in RT position (P = 0.000). Schematically, it was increased by 1% when the slope of operating table was increased by 5degrees. But, the CO and PAP were significant increased with decreased slopes of operating table in T position, and decreased with increased slopes of operating table in RT position (P = 0.045, 0.027). CONCLUSIONS: SVV is subjected to the posture, and we should take these findings into account on reading SVV for fluid therapy.

Tramadol can increase the serum level of serotonin, causing serotonin syndrome, which is a potentially life-threatening condition. Serotonin syndrome occurs when tramadol is used in combination with other drugs that affect serotonin. A patient who had been taking selective serotonin reuptake inhibitor and stopped at 10 days before surgery experienced intermittent heart rate elevation, tremor of the upper extremities and mental change after receiving an infusion of tramadol for postoperative pain control. Although he did not show the typical triad of serotonin syndrome (systemic autonomic dysfunction, neuromuscular impairment and mental status change), the patient was suspected to have serotonin syndrome caused by tramadol.
