BACKGROUND: The goal of this study was to evaluate whether preoperative pressure pain sensitivity testing is predictive of postoperative surgical pain. METHODS: Female subjects undergoing lower abdominal gynecologic surgery were studied. A pressure algometer was used preoperatively to determine the pressure pain threshold and tolerance. A visual analog scale (VAS) was used to assess postoperative pain. A State-Trait Anxiety Inventory was used to assess patients' anxiety. Subjects received intravenous patient-controlled analgesia for postoperative pain control. The preoperative pain threshold and tolerance were compared with the postoperative VAS pain score and morphine consumption. RESULTS: Forty women were enrolled. Their preoperative pressure pain threshold and tolerance were 141 +/- 65 kPa and 223 +/- 62 kPa, respectively. The VAS pain score in the postanesthesia care unit and at 24 h postoperatively were 81 +/- 24 and 31 +/- 10, respectively. Highly anxious patients had higher VAS pain scores in the postanesthesia care unit (P < 0.05). Pressure pain tolerance was significantly correlated with the VAS at 24 h postoperatively (P < 0.001, r = -0.52). Pressure pain tolerance after fentanyl administration (mean, 272 +/- 68 kPa) correlated significantly with morphine consumption in the first 24 h postoperatively (P < 0.002, r = -0.48). CONCLUSIONS: Assessment of preoperative pressure pain tolerance is significantly correlated with the level of postoperative pain. Pain tolerance assessment after fentanyl was administered and fentanyl sensitivity predicted the dose of analgesics used in the first 24 h after surgery. The algometer is thus a simple, useful tool for predicting postoperative pain and analgesic consumption.  相似文献

Introduction

Gabapentin is increasingly being used for the treatment of postoperative pain and a variety of psychiatric diseases, including chronic anxiety disorders. Trials have reported mixed results when gabapentin has been administered for the treatment of preoperative anxiety. We tested the hypothesis that gabapentin 1,200 mg vs placebo would reduce preoperative anxiety in patients who exhibit moderate to high preoperative anxiety.

Methods

A blinded randomized controlled trial was conducted from September 2009 to June 2011 at the Toronto General Hospital. Following ethics approval and informed consent, 50 female patients with a 0-10 numeric rating scale (NRS) anxiety score of greater than or equal to 5/10 consented to receive either gabapentin 1,200 mg (n = 25) or placebo (n = 25) prior to surgery. Randomization was computer generated, and the Investigational Pharmacy was responsible for the blinding and dispensing of medication. All patients and care providers, including physicians, nurses, and study personnel, were blinded to group allocation. Before administering the study medication, baseline anxiety levels were measured using a NRS, the Spielberger State-Trait Anxiety Inventories, the Pain Catastrophizing Scale, and the Pain Anxiety Symptoms Scale-20. Baseline pain intensity (0-10 NRS) and level of sedation (0-10 NRS and Richmond Agitation-Sedation Scale [RASS]) were also measured. Two hours after the administration of gabapentin or placebo (prior to surgery), patients again rated their anxiety, pain, and sedation levels using the same measurement tools as at baseline. The main outcome was a reduction in preoperative anxiety.

Results

Forty-four patients (22 treated with gabapentin 1,200 mg and 22 treated with placebo) were included in the analysis of the primary outcome. Analysis of covariance in which pre-drug NRS anxiety scores were used as the covariate showed that post-drug preoperative NRS anxiety (Effect size, 1.44; confidence interval [CI] 0.19 to 2.70) and pain catastrophizing (Effect size, 0.43; CI 0.12 to 0.74) scores were significantly lower in the gabapentin group than in the placebo control group, respectively. Post-drug sedation (Effect size, ?3.02; CI ?4.28 to ?1.77) and RASS (Effect size, 0.41; CI 0.12 to 0.71) scores were significantly higher in the gabapentin group than in the placebo group, respectively.

Conclusions

Administration of gabapentin 1,200 mg prior to surgery reduces preoperative NRS anxiety scores and pain catastrophizing scores and increases sedation prior to entering the operating room. These results suggest that gabapentin 1,200 mg may be a treatment option for patients who exhibit high levels of preoperative anxiety and pain catastrophizing; however, the sedative properties of the medication and the possibility of delayed postoperative discharge in the elective ambulatory population need to be considered.  相似文献

BACKGROUND CONTEXT: Some researchers have found a correlation of poor treatment outcomes in patients with low back pain and abnormal psychological profiles, whereas others have failed to confirm this correlation. A critical feature of this debate has been whether abnormal psychological profiles seen in patients with back pain are the result of the ongoing back pain or whether pre-existing psychological features predispose to a poor clinical outcome. PURPOSE: To determine the relationship of psychometric testing scores to the presence and duration of back pain of differing causes. STUDY DESIGN/SETTING: This was a prospective observational study of the psychological profiles of groups of patients with low back pain and controls. PATIENT SAMPLE: Subjects having a variety of painful back conditions (n=310) were compared with a control group of subjects without low back complaints who had undergone cervical spine surgery (n=73). OUTCOMES MEASURES: Psychometric testing (Modified Zung and Modified Somatic Pain Questionnaire) was performed along with pain scores (visual analog scale [VAS]), a standardized Low Back Pain Questionnaire, and the Oswestry Low Back Pain Disability Questionnaire in the evaluation of back pain and control subjects. METHODS: The subjects with painful back conditions included patients with presumed discogenic pain undergoing discography (n=95); patients with symptomatic isthmic spondylolisthesis coming to fusion (n=61); patients with chronic vertebral osteomyelitis before diagnosis and treatment (n=39). There was also a nonpatient group of soldiers with chronic low back pain not seeking medical care (n=115). The control subjects without low back pain consisted of a group who had undergone cervical spine surgery (n=73). Psychometric testing was performed and compared in the evaluation of subjects having these different painful back conditions. Analysis was done comparing pain scores, function scores, and psychological testing scores between the symptomatic and asymptomatic groups. RESULTS: The VAS maximum in last week score for the entire group was 7.1, and scores were not significantly different in all low back pain groups. The Oswestry scores were poorest in the discography group compared to spondylolisthesis and osteomyelitis. Functional scores were similar in the soldiers with low back pain and controls without low back pain. Both Depression and Somatic Pain scores were most abnormal in the discogenic low back pain group. Only 21% of this group had normal scores, compared with 71% of the spondylolisthesis group, 79% of osteomyelitis group, and 88% of the group with chronic low back pain not seeking treatment (p<.001 in all groups). The asymptomatic control group had 85% normal scores. CONCLUSIONS: Despite similar pain levels and pain duration, patients with the discographic diagnosis of discogenic back pain have poorer functional scores and very abnormal psychological scores compared with other subjects with chronic low back pain resulting from spondylolisthesis requiring surgery or chronic pyogenic osteomyelitis. Chronic moderately severe mechanical low back pain in healthy subjects was not associated with abnormal psychological scores or functional disability.  相似文献

BACKGROUND AND OBJECTIVE: The study compared the analgesic efficacy and safety of two preoperatively administered cyclo-oxygenase-2 inhibitors, celecoxib and rofecoxib. METHODS: Ninety adult patients undergoing thyroid surgery were divided into three groups (each n = 30). They were given a single oral dose of placebo, celecoxib 200 mg or rofecoxib 50 mg 1 h before induction of anaesthesia. All patients received a standard anaesthetic. Intraoperative blood loss was measured. Pain scores, sedation scores, heart rate, mean arterial pressure and respiratory rate were noted at 0, 1, 2, 4, 6, 12 and 24 h postoperatively. Analgesic (meperidine) requirements and adverse effects were recorded during the first postoperative 24 h. RESULTS: Compared with placebo, pain scores were significantly lower with rofecoxib at all time points (P < 0.05) and were significantly lower with celecoxib (P < 0.05) during the first 4 h. Pain scores were significantly lower with rofecoxib compared with celecoxib at 6, 12 and 24 h (P < 0.05). The average cumulative 24 h meperidine dose was significantly lower with both celecoxib (54.9 +/- 34.4mg) and rofecoxib (42.8 +/- 40.9 mg) compared with placebo (76.8 +/- 6.2 mg) (P < 0.01 and P < 0.001, respectively). There were no differences in the intraoperative blood loss, heart rate, mean arterial pressure, respiratory rate, sedation scores and incidence of adverse effects among groups. CONCLUSIONS: The preoperative administration of rofecoxib 50 mg and less so of celecoxib 200 mg provide a significant analgesic benefit with regard to postoperative pain relief and decrease in additional opioid requirements after thyroid surgery.  相似文献

BACKGROUND: Most studies of preemptive or preventive analgesia restrict outcomes to pain and analgesic consumption in the acute postoperative period. The potential longer-term effects on these and other domains of functioning have received little empirical attention. The purpose of this study was to follow up patients who had received general anesthesia plus epidural fentanyl and lidocaine before (group 1) or after (group 2) incision or general anesthesia plus a sham epidural (group 3). METHODS: Patients were contacted approximately 3 weeks and 6 months after surgery. A follow-up pain questionnaire and the McGill Pain Questionnaire were administered by telephone. The Mental Health Inventory and Pain Disability Index were mailed to patients, completed, and mailed back. RESULTS: One hundred thirty-one of the 141 patients (93%) were reached 3 weeks after surgery (n = 41, n = 48, and n = 42 in groups 1, 2, and 3, respectively), and 109 (77%) were reached at 6 months (n = 35, n = 37, and n = 37 in groups 1, 2, and 3, respectively). Multivariate analysis of covariance indicated that that even after controlling for age and presence or absence of preoperative pain, Pain Disability Index scores (mean +/- SD) at the first follow-up were significantly lower in group 1 (17.3 +/-12.8) and group 2 (18.1 +/-17.0) compared with group 3 (26.3 +/- 18.3). McGill Pain Questionnaire and Mental Health Inventory scores did not differ significantly among the groups. There were no significant differences at the 6-month follow-up. CONCLUSION: The short-term beneficial effects of preventive epidural analgesia translated into less pain disability 3 weeks after surgery. Progress in understanding the processes involved in postsurgical recovery and the risk factors for chronic postsurgical pain would be aided by baseline and postsurgical measures of relevant psychological, emotional, and physical variables.  相似文献
