Worldwide, long-acting bupivacaine is the most popular local anesthetic for spinal anesthesia in parturients undergoing elective cesarean delivery. With advances in surgical techniques, e.g., the Misgav Ladach method, and shorter duration of surgery, the local anesthetic mepivacaine, with an intermediate duration of action, may be a reasonable alternative. Our aim in the present study was to evaluate the effects of 2% hyperbaric mepivacaine alone, or combined with either intrathecal fentanyl (5 and 10 microg), or sufentanil (2.5 and 5 microg), on sensory, motor, and analgesic block characteristics, hemodynamic variables, and neonatal outcome in a randomized, prospective, and double-blinded study (n = 100, 20 parturients per group, singleton pregnancy, >37 wk of gestation). No parturient experienced intraoperative pain. The average duration of motor block Bromage 3 in all groups was 68 min, and resolution time to Bromage 0 was 118 min. Maximal cephalad sensory block level was T3-6 and could be established within 6 min. Complete analgesia was significantly prolonged in all groups receiving intrathecal opioids, yet, with sufentanil 5 microg, even the duration of effective analgesia was significantly extended. Neonatal outcome was not affected by intrathecal opioid administration. In conclusion, 2% hyperbaric mepivacaine is a feasible local anesthetic for spinal anesthesia in parturients undergoing elective cesarean delivery, particularly with short duration of surgery. IMPLICATIONS: Sensory, motor, and analgesic block characteristics of the local anesthetic mepivacaine alone or combined with intrathecal opioids were studied in parturients undergoing elective cesarean delivery in a randomized, double-blinded clinical trial. Mepivacaine was found to be an acceptable local anesthetic for spinal anesthesia in parturients undergoing cesarean delivery. In combination with sufentanil 5 microg, complete and effective analgesia were significantly prolonged.

Acute withdrawal syndromes, including agitation and a long weaning time, are common adverse effects after long-term sedation with midazolam. We performed this study to determine whether the sequential use of midazolam and propofol could reduce adverse effects as compared with midazolam alone. We studied 26 patients receiving mechanical ventilation for three or more days after surgery. Patients were randomly assigned to two groups. In Group M, patients were sedated with midazolam alone. In Group M-P, midazolam was switched to propofol approximately 24 h before the expected stopping of sedation. The level of sedation was maintained at 4 or 5 on the Ramsay sedation scale. The sedation agitation scale was evaluated for 24 h after extubation. The recovery time from stopping of sedation to extubation was significantly shorter in Group M-P (1.3 +/- 0.4 h) compared with Group M (4.0 +/- 2.4 h). The incidence of agitation in Group M-P (8%) was significantly less frequent than that in Group M (54%). The results indicate that sequential use of midazolam and propofol for long-term sedation could reduce the incidence of agitation compared with midazolam alone. IMPLICATIONS: Our study indicates that sequential use of midazolam and propofol could reduce the incidence of agitation compared with midazolam alone.

In this randomized study, we evaluated the quality of postoperative analgesia and the incidence of side effects of continuous thoracic epidural levobupivacaine 15 mg/h in 2 different concentrations: 0.5%, 3 mL/h (n = 33) or 0.15%, 10 mL/h (n = 27). The following variables were registered within 48 h: sensory block, pain scores, rescue morphine consumption, motor blockade, hemodynamics, sedation, nausea and vomiting, and patient satisfaction. The two groups were similar with regard to demographics, cephalad level of sensory block, quality of analgesia, morphine consumption, side effects, and high satisfaction rate. Motor blockade was weaker in the 0.5% group (P = 0.025), with a significantly increased hemodynamic stability, compared with the 0.15% group (P = 0.004). In conclusion, the same dose of levobupivacaine provides an equal quality of analgesia in small- or large-volume continuous epidural infusion and decreases the incidence of motor blockade and hemodynamic repercussions. This is in accordance with the assumption that the total dose of local anesthetics determines the spread and quality of analgesia. IMPLICATIONS: We demonstrated that a large concentration/small volume of levobupivacaine given as a continuous thoracic epidural infusion provided an equal quality of postoperative analgesia as a small-concentration/large-volume infusion and induced less motor blockade and fewer hemodynamic repercussions.

Extensive clinical experience and many studies support the use of i.v. patient-controlled analgesia (i.v. PCA) and regional anesthesia techniques for the treatment of postoperative pain in children. In contrast, little has been reported about the ability of children to use patient-controlled epidural analgesia (PCEA) or about the efficacy of this technique. We report a descriptive analysis of prospectively recorded data in 128 children (132 procedures) in whom PCEA was used for acute postoperative pain control. Satisfactory analgesia was obtained in 119 patients (90.1%) for up to 103 h with no episodes of desaturation and without clinical evidence of toxicity or serious adverse effects. Analgesia was satisfactory with the initial settings in 89 patients; in 38 others, this was achieved with changes in PCEA settings or solution. Five patients were switched to i.v. PCA because of inadequate analgesia. Eight patients with satisfactory analgesia were converted to i.v. PCA because of adverse effects. Children as young as 5 yr had the cognitive ability to understand and the willingness to use PCEA, consistent with reported use of i.v. PCA. Careful attention should be paid to the total hourly local anesthetic dose to avoid exceeding the recommended limits. Our prospectively collected data demonstrate that PCEA provides satisfactory analgesia with a small incidence of adverse side effects in children and should be considered along with other strategies in pediatric postoperative pain management. IMPLICATIONS: A descriptive analysis of prospectively recorded data in 132 children receiving patient-controlled epidural analgesia for postoperative pain relief demonstrates satisfactory analgesia without serious toxicity or side effects in children as young as 5 yr. This modality should be considered as another strategy in pediatric postoperative pain management.

CONTEXT: The risk-benefit ratio of invasive vs medical management of elderly patients with symptomatic chronic coronary artery disease (CAD) is unclear. The Trial of Invasive versus Medical therapy in Elderly patients (TIME) recently showed early benefits in quality of life from invasive therapy in patients aged 75 years or older, although with a certain excess in mortality. OBJECTIVE: To assess the long-term value of invasive vs medical management of chronic CAD in elderly adults in terms of quality of life and prevention of major adverse cardiac events. DESIGN: One-year follow-up analysis of TIME, a prospective randomized trial with enrollment between February 1996 and November 2000. SETTING AND PARTICIPANTS: A total of 282 patients with Canadian Cardiac Society class 2 or higher angina despite treatment with 2 or more anti-anginal drugs who survived for the first 6 months after enrollment in TIME (mean age, 80 years [range, 75-91 years]; 42% women), enrolled at 14 centers in Switzerland. INTERVENTIONS: Participants were randomly assigned to undergo coronary angiography followed by revascularization (if feasible) (n = 140 surviving 6 months) or to receive optimized medical therapy (n = 142 surviving 6 months). MAIN OUTCOME MEASURES: Quality of life, assessed by standardized questionnaire; major adverse cardiac events (death, nonfatal myocardial infarction, or hospitalization for acute coronary syndrome) after 1 year. RESULTS: After 1 year, improvements in angina and quality of life persisted for both therapies compared with baseline, but the early difference favoring invasive therapy disappeared. Among invasive therapy patients, later hospitalization with revascularization was much less likely (10% vs 46%; hazard ratio [HR], 0.19; 95% confidence interval [CI], 0.11-0.32; P<.001). However, 1-year mortality (11.1% for invasive; 8.1% for medical; HR, 1.51; 95% CI, 0.72-3.16; P =.28) and death or nonfatal myocardial infarction rates (17.0% for invasive; 19.6% for medical; HR, 0.90; 95% CI, 0.53-1.53; P =.71) were not significantly different. Overall major adverse cardiac event rates were higher for medical patients after 6 months (49.3% vs 19.0% for invasive; P<.001), a difference which increased to 64.2% vs 25.5% after 12 months (P<.001). CONCLUSIONS: In contrast with differences in early results, 1-year outcomes in elderly patients with chronic angina are similar with regard to symptoms, quality of life, and death or nonfatal infarction with invasive vs optimized medical strategies based on this intention-to-treat analysis. The invasive approach carries an early intervention risk, while medical management poses an almost 50% chance of later hospitalization and revascularization.

OBJECTIVE: To prospectively examine the course of pain and other neurologic complaints in patients with acute whiplash injury and in controls with acute ankle injury. METHODS: Patients with acute whiplash (n = 141) and ankle-injured controls (n = 40) were consecutively sampled, and underwent interview and examination after 1 week and 1, 3, 6, and 12 months. Outcome measures were pain intensity, pain frequency, and associated symptoms. RESULTS: Initial overall pain intensity above lower extremities (pain in neck, head, shoulder-arm, and low back) was similar in patients with whiplash (median Visual Analogue Scale [VAS](0-100) of 20 [25th and 75th percentile, 4, 39]) and ankle-injured controls (median VAS(0-100) of 15 [5, 34]). Whiplash-injured patients reported median overall VAS(0-100) pain intensity above lower extremities of 23 (12, 40) after 11 days and 14 (12, 40) after 1 year. Controls reported pain intensity of 0 (0, 4) after 12 days and 0 (0, 9) after 1 year. Reported overall pain frequency above lower extremities was 96% after 11 days and 74% after 1 year in whiplash-injured patients and 33% after 12 days and 47% after 1 year in controls. Associated neurologic symptoms were two to three times more common after whiplash injury. Correlation was found between pain intensity and associated symptoms in whiplash-injured patients but not controls. CONCLUSION: Pain occurs with high frequency but low intensity after whiplash and ankle injury. Associated neurologic symptoms were not correlated to pain in ankle-injured controls, but were correlated to pain in patients with whiplash injury. Persistent symptoms in whiplash-injured patients may be caused by both specific neck injury-related factors and nonspecific post-traumatic reactions. Disability was only encountered in the whiplash group.

Recent developments in chronic pain research suggest that effectiveness of cognitive-behavioral therapy (CBT) may be optimized when applying early, customized treatments to patients at risk. For this purpose, a randomized, controlled trial with tailor-made treatment modules was conducted among patients with relatively early rheumatoid arthritis (RA disease duration of <8 years), who had been screened for psychosocial risk profiles. All participants received standard medical care from a rheumatologist and rheumatology nurse consultant. Patients in the CBT condition additionally received an individual CBT treatment with two out of four possible treatment modules. Choice of treatment modules was determined on the basis of patient priorities, which resulted in most frequent application of the fatigue module, followed by the negative mood, social relationships and pain and functional disability modules. Analyses of completers and of intention-to-treat revealed beneficial effects of CBT on physical, psychological and social functioning. Specifically, fatigue and depression were significantly reduced at post-treatment and at the 6-month follow-up in the CBT condition in comparison to the control condition, while perceived support increased at follow-up assessment. In addition, helplessness decreased at post-treatment and follow-up assessment, active coping with stress increased at post-treatment, and compliance with medication increased at follow-up assessment in the CBT condition in comparison to the control condition. Results indicate the effectiveness of tailor-made CBT for patients at risk in relatively early RA, and supply preliminary support for the idea that customizing treatments to patient characteristics may be a way to optimize CBT effectiveness in RA patients.
