Persistent hiccups after attempted interscalene brachial plexus block.

OBJECTIVE: We describe a case of persistent hiccups after attempted interscalene brachial plexus block. CASE REPORT: A 38-year-old man was admitted for arthroscopic repair of a right shoulder injury. An interscalene block was attempted in the preoperative area and combined with general anesthesia for surgery. The procedure lasted 5(1/4) hours. After transfer to the recovery room, the patient complained of severe right shoulder pain and had no discernible sensory or motor block. He was noted to be hiccuping. The patient was discharged home the following morning but returned 2 days later complaining of persistent hiccups since surgery, with associated insomnia and nausea. He was readmitted and given chlorpromazine 50 mg intravenously every 8 hours and metoclopramide 10 mg intravenously every 6 hours. The patient was discharged 4 days later on chlorpromazine 25 mg by mouth every 8 hours and baclofen 5 mg by mouth every 12 hours, with hiccups greatly reduced in both intensity and frequency. Hiccups ceased 1 day after discharge. Eighteen days after surgery, he was off all medication with no return of his hiccups; 1 month later he remains hiccup free. CONCLUSIONS: Persistent hiccups have many postulated causes, including several that are common in the perioperative period, but this is the first time to our knowledge that persistent hiccups have been described in association with attempted interscalene brachial plexus block.

Propofol sedation for longitudinal pediatric neuroimaging research.

There is disagreement about allowing propofol sedation for research magnetic resonance imaging/spectroscopy (MRI/MRS) in children. Our study is the first to provide relevant safety and efficacy data. With institutional approval, 108 research MRI/MRS procedures under propofol sedation were performed longitudinally on children at ages 3-4 years (N=59) and 6-7 years (N=49). Sedation parameters, physiological values, and outcome data were collected. Success rate for acquisition of satisfactory quality MRI/MRS during propofol sedation was compared with that in typically developing, age-matched sleeping children. Only 5 minor events (2 with need to insert an oral airway, 2 with premature termination of study, 1 with bradycardia not requiring treatment) and no major events occurred. These safety/efficacy data are equal to or better than previously reported with propofol for clinically indicated procedures. A high percentage of parents of children participating in MRI/MRS studies at 3-4 years of age returned with their child at 6-7 years of age, and longitudinal follow-up was not adversely impacted by their child's experience with sedation. The success rate of data acquisition was significantly higher during propofol sedation (98%) than during late-night sleep studies in typically developing children (30%-50%). We conclude that propofol sedation for research MRI/MRS is safe and effective when children of appropriate ASA class are selected, supplemental oxygen is delivered, and sedation and monitoring are done by an experienced anesthesiologist.

Perioperative rofecoxib plus local anesthetic field block diminishes pain and recovery time after outpatient inguinal hernia repair.

In this study, we compared pain scores after inguinal herniorrhaphy in patients treated by preincisional local anesthetic field block (PL), or PL combined with perioperative rofecoxib, with controls who received standard care. Seventy-five patients having herniorrhaphy under general anesthesia were randomly assigned to receive a placebo pill preoperatively, and for 5 days postoperatively (CONT); preoperative bupivacaine field block and perioperative placebo (PL); preoperative field block plus rofecoxib, 50 mg preoperatively and for 5 days postoperatively (PLR). Bupivacaine infiltration in the wound at closure, IV fentanyl and acetaminophen/oxycodone were administered postoperatively to all. Discharge time, pain scores (0-10), analgesic use, and satisfaction scores (1-6) were compared using analysis of variance. PLR patients had lower maximum pain scores (worst pain) in the postanesthesia care unit (3.7 versus 5.3, P = 0.02) and at 24 h (5.3 versus 6.8, P = 0.03), were discharged 38 min sooner (P = 0.01), required 28% less oxycodone 0-24 h after discharge (P = 0.04), and reported higher satisfaction scores compared with CONT. Pain in PL was less than CONT for 30 min. There were no differences among the 3 groups after 24 h postoperatively. We conclude that perioperative rofecoxib with PL reduces in-hospital recovery time, decreases pain scores and opioid use, and improves satisfaction scores in the first 24 h after surgery.
