The effect of four days of preoperative lactulose on posthaemorrhoidectomy pain was studied in a prospective double blind randomized trial. All patients received lactulose on admission to hospital, 20 received lactulose for four days before admission, and 22 received placebo. The preoperative lactulose treatment group suffered significantly less pain on defecation for the first four days that they opened their bowels (visual analogue scores in cm: day 1, 4.4 v 5.9; day 2, 4.1 v 6.3; day 3, 4.5 v 6.1; day 4, 4.6 v 6.5), suffered significantly less pain during the first two 24 hour periods after defecation (visual analogue scores in cm: day 1, 5.0 v 7.0; day 2, 3.9 v 6.1), and required significantly less analgesia daily after defecation (0.76 g paracetamol/day v 1.29 g paracetamol/day). These results show that lactulose given for four days preoperatively reduces pain after haemorrhoidectomy. 相似文献

OBJECTIVE--To evaluate the experience of a year''s audit of care of medical inpatients. DESIGN--Audit of physicians by monthly review of two randomly selected sets of patients'' notes by 12 reviewers using a detailed questionnaire dedicated to standards of medical records and to clinical management. Data were entered into a database and summary statistics presented quarterly at audit meetings. Assessment by improvement in questionnaire scores and by interviewing physicians. SETTING--1 District general hospital. PARTICIPANTS--About 40 consultant physicians, senior registrars, and junior staff dealing with 140 inpatient records. MAIN OUTCOME MEASURES--Median scores (range 1 to 9) for each item in the questionnaire; two sets of notes were discussed monthly at "general" audit meetings and clinical management of selected common conditions at separate monthly meetings. RESULTS--A significant overall increase in median scores for questions on record keeping occurred after the start of the audit (p less than 0.01), but interobserver variation was high. The parallel audit meetings on clinical management proved to be more successful than the general audits in auditing medical care and were also considered to be more useful by junior staff. CONCLUSIONS AND ACTION--Medical audit apparently resulted in appreciable improvements in aspects of care such as clerking and record keeping. Analysis of the scores of the general audits has led to the introduction of agreed standards that can be objectively measured and are being used in a further audit, and from the results of the audits of clinical management have been developed explicit guidelines, which are being further developed for criterion based audit. 相似文献

Terminally ill cancer patients were given the Brompton mixture and a phenothiazine in an attempt to control their pain. The mixture was administered to patients in three hospital environments: a palliative care unit (PCU), general wards and private rooms. Pain was measured in 92 patients with the McGill-Melzack Pain Questionnaire. The Brompton mixture controlled pain in 90% of patients in the PCU and in 75% to 80% of patients in the wards or private rooms. The differences in pain scores between the PCU patients and the other groups were significant. The mixture produced substantial decreases in the three major dimensions of pain: sensory, affective and evaluative. Comparison of these results with data obtained in an outpatient pain clinic showed that the Brompton mixture was strikingly more effective than the traditional methods of managing cancer pain. 相似文献

Until recently, the clinical significance of post-surgical pain and its undertreatment were for the most part unappreciated. Recognition that inadequate analgesia adversely affects the patient's cardiovascular, pulmonary, and emotional status has spurred development of new and highly effective methods of controlling pain. With the introduction of spinal opioid and patient-controlled analgesia (PCA) came the realization that, while such forms of therapy provided superior pain relief, they were not without their own unique and occasionally serious side effects. For this reason, both techniques are more safely provided by highly trained members of a dedicated acute/post-surgical pain service. Although spinal opioid (epidural, intrathecal) techniques are invasive and require patient cooperation, they have a high degree of safety in low-risk populations (ASA 1 and 2). The major therapeutic advantage of spinal opioids is their ability to prevent pain from being perceived. PCA permits patients to titrate intravenous opioids in proportion to their particular level of pain intensity. Although PCA provides effective pain "relief," the technique is incapable of preventing pain from being appreciated. A number of studies have observed that pain scores in patients successfully employing PCA were significantly higher than those noted in individuals treated with epidural opioids. Nevertheless, the control gained by self-administration, uniformity of analgesia, and low level of adverse results associated with PCA provides higher patient satisfaction and decreased sedation when compared with traditional intramuscular dosing. The effectiveness of PCA may be improved by adjusting for patient variables, utilizing opioids having rapid onset, the addition of a basal infusion, and supplementation with non-steroidal anti-inflammatory agents. Interpleural analgesia represents an important therapeutic option in patients sensitive to opioid-induced respiratory depression. The technique is more effective when local anesthetic solutions are continually infused. Analgesic efficacy may be further enhanced by the addition of "low-dose" PCA. 相似文献

In a double-blind prospective trial 26 consecutive patients with proved ureteric colic were allocated at random to receive 100 mg pethidine or 0.3 mg buprenorphine by intramuscular injection. Pain relief was assessed by standard linear analogue and ordered categories scales. The mean pain relief on the linear analogue scale was 3.80 +/- SEM 0.64 in patients receiving pethidine and 6.86 +/- 0.40 in those receiving buprenorphine (p less than 0.001). The corresponding values for mean pain relief in the ordered categories scale was 1.78 +/- 0.26 v 2.76 +/- 0.20 (p less than 0.01). These observations suggest that buprenorphine is superior to pethidine as analgesia in ureteric colic. 相似文献

Fifty patients undergoing hysterectomy or cholecystectomy took part in a trail of postoperative analgesia provided by either intramuscular morphine or controlled-release morphine sulphate tablets orally. Respiratory function and plasma catecholamine concentrations were measured after operation and pain was assessed by using a linear analogue scoring method. Controlled-release morphine sulphate produced comparable pain relief with that of intramuscular morphine, and depression of respiratory function after operation was similar with the two analgesic regimens. The mean total dose of drug per patient given over 48 h to patients undergoing hysterectomy was 115 mg for morphine sulphate and 53 mg for morphine. Patients undergoing cholecystectomy received 130 mg morphine sulphate or 76 mg morphine. There was more sedation after operation in those patients undergoing hysterectomy who received morphine sulphate tablets. Morphine sulphate tablets produced satisfactory postoperative analgesia compared with intramuscular morphine: both regimens were acceptable to the patients. 相似文献

Aim of this study was to evaluate level of analgesia and hemodynamic response to spinal anesthesia obtained by administering 15 mg 0.5% isobaric bupivacaine at L2-3 vs. L3-4 interspace for inguinal herniorrhaphy, since studies comparing analgesia and hemodynamic response at the L2-3 vs. L3-4 interspaces are lacking. In a prospective, randomized clinical study that encountered 72 patients undergoing elective inguinal herniorrhaphy randomly allocated in to two equal groups L2-3 (N = 36) and L3-4 (N = 36) according to lumbar interspace where intrathecal injection of bupivacaine was administered. Analgesia was evaluated by intraoperative "rescue" fentanyl requirements, the absence of pain and the maximal visual analogue scale (VAS) scores reached per patient during the operation. The severity of intraoperative pain was quantified by a 10 cm VAS scale (VAS 0: no pain to 10: worst pain imaginable) every 5 minutes after skin incision until the end of the operation. VAS > 3 was treated with intravenous fentanyl 25 microg. Hemodynamic response was monitored and evaluated, heart rate was continuously monitored as well as, baseline systolic, diastolic and mean arterial pressure prior to induction and every 5 minute after applying spinal anesthesia until surgical completion. Intraoperative fentanyl requirements were significantly higher in group L3-4 (L2-3 0%, 97.5% confidence interval [CI] 0.0-0.11 vs. L3-4 17%, 95% CI 0.07-0.32, p = 0.025). Absence of pain was significantly higher in L2-3 group at the beginning of the operation (L2-3 89%, 95% CI 0.74-0.96 vs. L3-4 67%, 95% CI 0.50-0.79, p = 0.047). The maximal VAS scores reached per patient during the operation in L2-3 group were lower then in L3-4 group (L2-3 median [M] 0, range [R] 0-3, L3-4 M 0, R 0-8, p = 0.014). There were no significant differences (p > 0.05) in the incidence of hypotension (L2-3 19%, 95% CI 0.09-0.35 vs. L3-4 17%, 95% CI 0.07-0.32) and bradycardia (L2-3 19%, 95% CI 0.09-0.35 vs. L3-4 8%, 95% CI 0.02-0.23). Spinal anesthesia with isobaric bupivacaine administered in L2-3 interspace for inguinal herniorrhaphy provides superior analgesia and equal hemodynamic stability as compared to neuroaxial anesthesia administered in the L3-4 interspace. 相似文献

BackgroundImpending pathologic fractures of the femur due to metastatic bone disease are treated with prophylactic internal fixation to prevent fracture, maintain independence, and improve quality of life. There is limited data to support an optimal perioperative pain regimen.MethodsA proof of concept comparative cohort analysis was performed: 21 patients who received a preoperative fascia iliacus nerve block (FIB) were analyzed retrospectively while 9 patients treated with local infiltrative analgesia (LIA) were analyzed prospectively. Primary outcomes included: visual analog scale (VAS) pain scores, narcotic requirements and hospital length of stay. Patient cohorts were compared via two-sample t-tests and Fischer’s exact tests. Differences in VAS pain scores, length of stay and morphine milligram equivalents (MME) were assessed with Wilcoxon rank sum.ResultsThe LIA group had more patients treated with preoperative narcotics (p=0.042). There were no significant differences between the FIB and LIA groups in MME utilized intraoperatively (30.0 vs 37.5, p=0.79), on POD 0 (38.0 vs 30.0, p=0.93), POD 1 (46.0 vs 55.5, p=0.95) or POD 2 (40.0 vs 60.0 p=0.73). There were no significant differences in analog pain scale at any time point or in hospital length of stay (78 vs 102 hours, p=0.86).ConclusionDespite an increased number of patients being on preoperative narcotics in the LIA group, use of LIA compared with FIB is not associated with an increase in VAS pain scores, morphine milligram equivalents (MME), or length of hospital stay in patients undergoing prophylactic internal fixation of impending pathologic femur fractures.Level of Evidence: III 相似文献

Pain exhibits temporal variations in intensity due to multiple factors, including endogenous neuroendocrine and various external influences that vary over the 24?h. Also, medications can vary in potency and/or toxicity according to the time when they are administered. However, there is no consensus among studies regarding the 24-h pattern of analgesia during labor. Taking into account the time-of-day when labor analgesia is administered, this study aimed to answer two questions: (i) Is there diurnal variation in visual analogue scale (VAS)–rated pain relief and duration of intrathecal analgesia in patients undergoing labor analgesia? (ii) If there is, what is the influence of the duration of labor on the diurnal variation of the level of pain relief and duration of intrathecal analgesia? This prospective cohort included 41 healthy, nulliparous women in the first stage of labor undergoing spinal-epidural (CSE) analgesia using fentanyl combined with bupivacaine. Subjects had an epidural catheter fitted for additional, patient-controlled analgesia (PCA) if their pain relief was unsatisfactory. The number of VAS assessments (n?=?558) was divided into six time periods of the 24?h. The adjusted coefficient of determination (r2), the proportion of the variance explained by the association between the duration of labor and the temporal pattern of the outcomes variable, was 58% (r2?=?0.58) for pain relief and 44% (r2?=?0.44) for duration of intrathecal analgesia. The peak effect of labor analgesia occurred between 02:00 and 05:59?h. However, the duration of intrathecal analgesia showed two peaks, i.e., at ~00:00 and ~12:00?h. These results demonstrate that labor analgesia achieved by fentanyl combined with bupivacaine shows a diurnal pattern in pain relief and duration of spinal analgesia. However, part of these temporal patterns was explained by the association with duration of labor. (Author correspondence: caumo@cpovo. net) 相似文献

OBJECTIVE--To establish whether positive suggestions given to a patient under general anaesthesia reduce postoperative pain and analgesic requirements. DESIGN--Prospective double blind randomised study. SETTING--Operating theatre and gynaecology ward of a teaching hospital. PATIENTS--63 Woman undergoing elective abdominal hysterectomy were randomised to be played either a tape of positive suggestions or a blank tape during the operation through a personal stereo system. INTERVENTIONS--Three women were withdrawn from the study. Anaesthesia was standardised for all of the women. Postoperative analgesia was provided through a patient controlled analgesia system for the first 24 hours. Pain scores were recorded every six hours. MAIN OUTCOME MEASURES--Morphine consumption over the first 24 hours after the operation; pain scores. RESULTS--Mean morphine requirements were 51.0 mg (95% confidence interval 42.1 to 60.0 mg in the women played positive suggestions; and 65.7 mg (55.6 to 75.7 mg) in those played a blank tape. The point estimate (95% confidence interval) for the difference of means was 14.6 mg (22.4%) (1.9 (2.9%) to 27.3 mg (41.6%] (p = 0.028). Pain scores were similar in the two groups. CONCLUSION--Positive intraoperative suggestions seem to have a significant effect in reducing patients'' morphine requirements in the early postoperative period. 相似文献

Epidural analgesia is considered the standard of care but cannot be provided to all patients Liposomal bupivacaine has been approved for field blocks such as transversus abdominis plane (TAP) blocks but has not been clinically compared against other modalities. In this retrospective propensity matched cohort study we thus tested the primary hypothesis that TAP infiltration are noninferior (not worse) to continuous epidural analgesia and superior (better) to intravenous opioid analgesia in patients recovering from major lower abdominal surgery. 318 patients were propensity matched on 18 potential factors among three groups (106 per group): 1) TAP infiltration with bupivacaine liposome; 2) continuous Epidural analgesia with plain bupivacaine; and; 3) intravenous patient-controlled analgesia (IV PCA). We claimed TAP noninferior (not worse) over Epidural if TAP was noninferior (not worse) on total morphine-equivalent opioid and time-weighted average pain score (10-point scale) within first 72 hours after surgery with noninferiority deltas of 1 (10-point scale) for pain and an increase less of 20% in the mean morphine equivalent opioid consumption. We claimed TAP or Epidural groups superior (better) over IV PCA if TAP or Epidural was superior on opioid consumption and at least noninferior on pain outcome. Multivariable linear regressions within the propensity-matched cohorts were used to model total morphine-equivalent opioid dose and time-weighted average pain score within first 72 hours after surgery; joint hypothesis framework was used for formal testing. TAP infiltration were noninferior to Epidural on both primary outcomes (p<0.001). TAP infiltration were noninferior to IV PCA on pain scores (p = 0.001) but we did not find superiority on opioid consumption (p = 0.37). We did not find noninferiority of Epidural over IV PCA on pain scores (P = 0.13) and nor did we find superiority on opioid consumption (P = 0.98). TAP infiltration with liposomal bupivacaine and continuous epidural analgesia were similar in terms of pain and opioid consumption, and not worse in pain compared with IV PCA. TAP infiltrations might be a reasonable alternative to epidural analgesia in abdominal surgical patients. A large randomized trial comparing these techniques is justified. 相似文献

A trial was conducted of Entonox for pain relief in minor, but painful, procedures which are conducted in wards, accident centres, and radiological units. The gas was self-administered by the patient using a demand apparatus. The administration was supervised by qualified nurses, specially trained in the properties of Entonox and the inhalational unit. The results confirm that the gas is safe in the hands of these personnel. Gratifying pain relief occurred in most patients with almost complete freedom from undesirable side effects. It is suggested that patient comfort in hospital can be considerably improved by utilizing this method of analgesia to the full. 相似文献

To examine fluctuations in numbers of patients on surgical wards the dates of admission from January of each of the 5556 patients admitted from 1 January 1985 to 31 December 1987 were examined during computerised audit of a single surgical firm. The numbers of patients under the care of the firm fluctuated widely, often exceeding the 38 beds nominally available. Duration of stay varied from two days or less (3062 admissions) to more than a month (163 admissions). One patient was in hospital for 278 days. The patients admitted for more than a month (2.9% of the total) filled 28% of the beds; not all these patients were elderly. A further increase in throughput of patients undergoing elective operations might be achieved by always admitting patients on the day of operation, and perhaps by discharging patients even sooner than at present. Efficiency would increase but so would overall costs. 相似文献

Circadian variation in biological rhythms has been identified as affecting both labour pain and the pharmacological properties of analgesics. In the context of pain, there is also a growing body of evidence suggesting the importance of adult attachment. The purpose of this study was to examine whether labour pain, analgesic consumption and pharmacological effect are significantly affected by the time of day and to analyse whether this circadian variation is influenced by women’s attachment style. This prospective observational study included a sample of 81 pregnant women receiving patient-controlled epidural analgesia (PCEA). Attachment was assessed with the Adult Attachment Scale – Revised. The perceived intensity of labour pain in the early stage of labour (3?cm of cervical dilatation and before the administration of PCEA) was measured using a visual analogue scale (VAS). Pain was also indirectly assessed by measuring the consumption of anaesthetics. The latency period and the duration of effect were recorded for a chronopharmacology characterisation. Pain, as assessed with the VAS, was significantly higher in the night-time group than in the daytime group. An insecure attachment style was significantly associated with greater labour pain at 3?cm of cervical dilatation (p?<?0.001) and before the beginning of analgesia (p?<?0.001) as well as with higher analgesic consumption and lower pharmacological efficacy (p?<?0.05). The time of day was significantly associated with the pharmacological effect: the latency period was longer at night, and the duration of the pharmacological effect was longer during the daytime. The interaction between time of day and attachment style was not significant for any of the study variables. Our results provide evidence of the importance of circadian variation in studying labour pain and the pharmacological effect of labour analgesia involving epidural blockage with a PCEA regimen. Moreover, although there was no evidence that attachment style influenced the circadian variation, these data emphasise that insecure attachment patterns are a risk factor for greater labour pain and analgesic consumption, which should be considered in pain management approaches. 相似文献
