Patient-controlled epidural analgesia or multimodal pain regimen with periarticular injection after total hip arthroplasty: a randomized, double-blind, placebo-controlled study.

The optimal postoperative analgesia after primary total hip arthroplasty remains in question. This randomized, double-blind, placebo-controlled study compared the use of patient-controlled epidural analgesia (PCEA) with use of a multimodal pain regimen including periarticular injection (PAI). We hypothesized that PAI would lead to earlier readiness for discharge, decreased opioid consumption, and lower pain scores. Forty-one patients received PAI, and forty-three patients received PCEA. Preoperatively, both groups were administered dexamethasone (6 mg, orally). The PAI group received a clonidine patch and sustained-release oxycodone (10 mg), while the PCEA group had placebo. Both groups received combined spinal-epidural anesthesia and used an epidural pain pump postoperatively; the PAI group had normal saline solution, while the PCEA group had bupivacaine and hydromorphone. The primary outcome, readiness for discharge, required the discontinuation of the epidural, a pain score of <4 (numeric rating scale) without parenteral narcotics, normal eating, minimal nausea, urination without a catheter, a dry surgical wound, no acute medical problems, and the ability to independently transfer and walk 12.2 m (40 ft). The mean time to readiness for discharge (and standard deviation) was 2.4 ± 0.7 days (PAI) compared with 2.3 ± 0.8 days (PCEA) (p = 0.86). The mean length of stay was 3.0 ± 0.8 days (PAI) compared with 3.1 ± 0.7 days (PCEA) (p = 0.46). A significant mean difference in pain score of 0.74 with ambulation (p = 0.01; 95% confidence interval [CI], 0.18 to 1.31) and 0.80 during physical therapy (p = 0.03; 95% CI, 0.09 to 1.51) favored the PCEA group. The mean opioid consumption (oral morphine equivalents in milligrams) was significantly higher in the PAI group on postoperative day 0 (43 ± 21 compared with 28 ± 23; p = 0.002) and postoperative days 0 through 2 (136 ± 59 compared with 90 ± 79; p = 0.004). Opioid-Related Symptom Distress Scale (ORSDS) composite scores for severity and bothersomeness as well as scores for nausea, vomiting, and itchiness were significantly higher in the PCEA group (p < 0.05). Quality of Recovery-40 scores and patient satisfaction were similar. PAI did not decrease the time to discharge and was associated with higher pain scores and greater opioid consumption but lower ORSDS scores compared with PCEA. The choice for analgesic regimen may depend on a particular patient's threshold for pain and the potential side effects.

Transcutaneous Electrical Acupoint Stimulation Improves the Postoperative Quality of Recovery and Analgesia after Gynecological Laparoscopic Surgery: A Randomized Controlled Trial.

Background. We conducted this prospective, randomized, double-blind, placebo-controlled study to evaluate the effects of transcutaneous electric acupoint stimulation (TEAS) on the quality of recovery (QoR) and postoperative analgesia after gynecological laparoscopic surgery. Methods. 74 American Society of Anesthesiologists physical status (ASA) I or II patients undergoing gynecological laparoscopic surgery were randomly allocated to TEAS or control groups. The primary outcome was the quality of recovery, which was assessed on the day before surgery and 24 h after surgery using a 40-item questionnaire. Secondary outcomes included postoperative pain scores, the incidence of postoperative nausea and vomiting (PONV), duration of postanesthesia care unit (PACU) stay, and patient's satisfaction. Results. The TEAS group had higher QoR scores than control group upon 24 h after surgery (177 versus 165; P < 0.001). Compared with the control group, postoperative pain scores and the cumulative number of opioids administered were lower in the TEAS group patients (P = 0.04). TEAS reduced the incidence of PONV and dizziness, as well as duration of PACU stay. Simultaneously, the patient's satisfaction scores were higher in the TEAS group (P = 0.002). Conclusion. Preoperative TEAS enhances QoR, improves postoperative analgesia and patient's satisfaction, alleviates postoperative side effects, and accelerates discharge after general anesthesia for gynecological laparoscopic surgery.

Transversus abdominis plane block reduces morphine consumption in the early postoperative period following microsurgical abdominal tissue breast reconstruction: a double-blind, placebo-controlled, randomized trial.

The analgesic efficacy of the transversus abdominis plane peripheral nerve block following abdominal tissue breast reconstruction has not been studied in a randomized controlled trial. The authors conducted a double-blind, placebo-controlled, 1:1 allocation, two-arm parallel group, superiority design, randomized controlled trial in patients undergoing microsurgical abdominally based breast reconstruction. Intraoperatively, epidural catheters were inserted under direct vision through the triangle of Petit on both sides of the abdomen into the transversus abdominis plane just before rectus fascial closure. Patients received either bupivacaine (study group) or saline (placebo group) through the catheters for 2 postoperative days. All patients received hydromorphone by means of a patient-controlled analgesic pump. The primary outcome was the difference in the parenteral opioid consumption on each postoperative day between the groups. The secondary outcome measures included the following: total in-hospital opioid; antinausea medication; pain, nausea, and sedation scores; Quality of Recovery Score; time to ambulation; and hospital stay duration. Between September of 2011 and June of 2013, 93 patients were enrolled: 49 received bupivacaine and 44 received saline. There were 11 postoperative complications (13 percent); none were related to the catheter. Primary outcomes were completed by 85 of 93 patients (91.3 percent); the mean parenteral morphine consumption was significantly reduced on postoperative day 1 in the bupivacaine group (20.7±20.1 mg) compared with 30.0±19.1 mg in the control group (p=0.02). There were no significant differences in secondary outcomes. Following abdominally based breast reconstruction, transversus abdominis plane peripheral nerve block is safe and significantly reduces morphine consumption in the early postoperative period.

Effects of preemptive ketamine on postoperative analgesia after total abdominal hysterectomy (TAH) under general anaesthesia

Background The concept of ‘Pre-emptive analgesia’ suggest that the best post operative pain management begins preoperatively. Preemptive low dose ketamine is effective in treating post operative pain after total abdominal hysterectomy.&#x0D; Objectives This study was designed to evaluate the analgesic efficacy of preemptive low dose ketamine in treating moderate to severe acute post operative pain in total abdominal hysterectomy surgery under general anesthesia.&#x0D; Methods Sixty patients aged between 35-50 years, weight between 45-65 kg with ASA physical status I &amp; II underwent elective total abdominal hysterectomy under general anesthesia were randomly divided into two groups. In group A, patients received 10 ml of normal saline I/V over 60-90 second before surgical incision. In group B, patients received 0.15 mg/kg ketamine (mixed with 10 ml normal saline) I/ V over 60-90 second before surgical incision. Anesthetic technique was standardized &amp; patients were interviewed regularly. Pain score, analgesic consumption, side effects &amp; quality of recovery score were recorded for 24 hours.&#x0D; Results Patient received preemptive ketamine had a statistically significant lower pain score in first 24 hours after operation compared with placebo group. Mean value of first analgesic demand in group A was 25.67±1.60 &amp; group B was 57.33±2.97 &amp; p = 0.00. Mean value of total opioids consumption in group A was 290.00±9.09 &amp; group B was 210.67±7.01 &amp; p = 0.00. Significant differences were observed between two groups regarding first analgesic demand &amp; total analgesic consumption. There were no significant differences between these two groups in respect to haemodynamic variable or side effects.&#x0D; Conclusion Preemptive low dose intra venous ketamine offer a safe, non opioid, well-tolerated analgesia with efficacy in moderate to severe post operative pain &amp; spare opioid consumption in the post operative pain management.&#x0D; JBSA 2012; 25(1): 3-8

A pilot study for a prospective, randomized, double-blind trial of the influence of anesthetic depth on long-term outcome.

Deep general anesthesia has been associated with increased mortality in 5 observational studies. The association may be causal or an epiphenomenon due to increased anesthetic sensitivity in high-risk patients. We conducted a pilot study to assess the feasibility of performing a definitive randomized controlled trial. The aims of the study were to determine whether anesthetic depth targeting in a high-risk group was feasible and to document anesthetic doses and arterial blood pressures associated with "deep" and "light" general anesthesia. ASA physical status III and IV patients, aged ≥60 years, having surgery lasting ≥2 hours, with expected hospital stay ≥2 days, and receiving general anesthesia were randomly allocated to a Bispectral Index (BIS) or spectral entropy (SE) target of 35 ("low" group) or 50 ("high" group). The primary end point was mean BIS or SE. Secondary end points were postanesthesia care unit length of stay and pain scores, quality of recovery score, hospital length of stay, postoperative complications, and death. A composite end point of postoperative complications (pneumonia, myocardial infarction, stroke, pulmonary embolism, heart failure, and death) was determined at 1 year. One hundred twenty-five patients were recruited. The mean of the median BIS/SE values for each patient during the maintenance phase of anesthesia in the low and high groups was significantly different: 39 vs 48 (mean difference 8 [95% confidence interval {CI95}, 6 to 10], P < 0.001). There was also a significant difference in mean volatile anesthetic administration (minimum alveolar concentration): 0.98 vs 0.64 (mean difference -0.35 [CI95, -0.44 to -0.26], P < 0.001) and target propofol concentrations: 4.0 vs 3.1 μg/mL (mean difference -0.8 [CI95, -1.2 to -0.3], P = 0.004). Intraoperative mean arterial blood pressures were similar (85 vs 87 mm Hg; mean difference 2 [CI95, -2 to 6], P = 0.86), and there were no differences in short-term recovery characteristics or hospital length of stay. There was a significant difference in the incidence of wound infection at 30 days (13% vs 3%; risk difference -10% [CI95, -21 to -0.1], P = 0.04). At 1 year, the composite rates of complications in the low and high groups were 28% and 17% (risk difference -11 [CI95, -25 to 4], P = 0.15) and mortality rates were 12% and 9%, respectively (risk difference -2 [CI95, -14 to 9], P = 0.70). This pilot study demonstrated that depth of anesthesia targeting with BIS or SE was achievable in a high-risk population with adequate separation of processed electroencephalogram monitor targets. The expected incidence of postoperative complications and mortality occurred. We conclude that a large, multicenter, randomized controlled trial is feasible.

Transversus abdominis plane block does not improve early or late pain outcomes after Cesarean delivery: a randomized controlled trial.

Cesarean delivery is a common surgical procedure with anticipated substantial postoperative pain. The addition of a transversus abdominis plane block (TAPB) to a multimodal analgesic regimen that includes intrathecal morphine may provide improved early pain outcomes and decrease the risk of chronic post-surgical pain. The purpose of this research was to assess the ability of an ultrasound-guided TAPB with low-dose ropivacaine to decrease early postoperative pain, opioid consumption, and risk of developing persistent pain when compared with a placebo block. Eighty-three women were randomly assigned to either a treatment (0.25% ropivacaine) or control group (0.9% saline) in this double-blind trial, and 74 women were included in the final analysis. Ultrasound-guided TAPBs were performed with an injection of 20mL of study solution per side. The primary outcome measures of this study were: pain at rest and pain after movement measured with a numeric rating scale, results of the Quality of Recovery-40 (QoR-40) questionnaire, and opioid consumption at 24 hr. These were used with an a priori sample size calculation to detect a 30% reduction in pain scores, a 10% improvement in QoR-40 score, and a 50% reduction in opioid consumption. Health quality and physical functioning were assessed using the Short Form 36 (SF-36®) Health Survey at 30days and six months. Assessment at 24 hr after Cesarean delivery revealed no clinically important differences between groups in postoperative pain, QoR-40, or opioid consumption. There were no clinically important differences between groups regarding measures of nausea, pruritus, vomiting, urine retention (2, 24, and 48 hr postoperatively), 24-hr QoR-40 sub-dimensions, or the SF-36 Health Survey (30days and six months postoperatively). Ultrasound-guided TAPB did not improve postoperative pain, quality of recovery, or opioid consumption 24 hr following surgery. Similar health and functioning (SF-36) at 30days and six months were reported by both groups. This trial was registered at ClinicalTrials.gov number: NCT01261637.

Ultrasound-guided Multilevel Paravertebral Blocks and Total Intravenous Anesthesia Improve the Quality of Recovery after Ambulatory Breast Tumor Resection

Regional anesthesia improves postoperative analgesia and enhances quality of recovery (QoR) after ambulatory surgery. This randomized, double-blinded, parallel-group, placebo-controlled trial examines the effects of multilevel ultrasound-guided paravertebral blocks (PVBs) and total intravenous anesthesia on QoR after ambulatory breast tumor resection. Sixty-six women were randomized to standardized general anesthesia (control group) or PVBs and propofol-based total intravenous anesthesia (PVB group). The PVB group received T1-T5 PVBs with 5 ml of 0.5% ropivacaine per level, whereas the control group received sham subcutaneous injections. Postoperative QoR was designated as the primary outcome. The 29-item ambulatory QoR tool was administered in the preadmission clinic, before discharge, and on postoperative days 2, 4, and 7. Secondary outcomes included block success, pain scores, intra- and postoperative morphine consumption, time to rescue analgesia, incidence of nausea and vomiting, and hospital discharge time. Data from sixty-four patients were analyzed. The PVB group had higher QoR scores than control group upon discharge (146 vs. 131; P < 0.0001) and on postoperative day 2 (145 vs. 135; P = 0.013); improvements beyond postoperative day 2 lacked statistical significance. None of the PVB group patients required conversion to inhalation gas-based general anesthesia or experienced block-related complications. PVB group patients had improved pain scores on postanesthesia care unit admission and discharge, hospital discharge, and postoperative day 2; their intraoperative morphine consumption, incidence of nausea and vomiting, and discharge time were also reduced. Combining multilevel PVBs with total intravenous anesthesia provides reliable anesthesia, improves postoperative analgesia, enhances QoR, and expedites discharge compared with inhalational gas- and opioid-based general anesthesia for ambulatory breast tumor resection.

Transversus abdominis plane infiltration for laparoscopic gastric banding: A pilot study

To estimate an effect size for the transversus abdominis plane (TAP) infiltration on quality of recovery in patients undergoing laparoscopic gastric band surgery. The pilot study was a randomized, double blinded, placebo controlled trial. Patients undergoing laparoscopic gastric band surgery were randomized to receive a bilateral TAP infiltration with 20 mL of 0.5% ropivacaine or saline. The evaluated outcomes included quality of recovery-40 (QoR-40) at 24 h, postoperative opioid consumption and pain. Data was examined using the Mann-Whitney U test. Nineteen subjects were recruited. There was a positive trend favoring the TAP infiltration group in global QoR-40 scores at 24 h after surgery, median [interquartile range (IQR)] of 175.5 (170-189) compared to 170 (160-175) in the control group (P = 0.06). There also a positive trend toward a lower cumulative opioid consumption in the TAP infiltration group, median (IQR) of 7.5 (2.5-11.5) mg iv morphine equivalents compared to 13 (7-21.5) in the control group (P = 0.07). Correlation analysis (Spearman's Rho) demonstrated an inverse relationship between 24 h cumulative opioid consumption and global QoR-40 scores, -0.49 (P = 0.03). The use of multimodal analgesic techniques to reduce opioid related side effects is particularly desirable in morbidly obese patients undergoing gastric reduction surgery. The TAP infiltration seems to have a clinically important effect in reducing postoperative opioid consumption and improve quality of recovery after laparoscopic gastric band surgery in morbid obese patients. Future studies to confirm the beneficial effects of the TAP infiltration in these patients are warranted.

Lorazepam does not improve the quality of recovery in day-case surgery patients

In day-case surgery, the effects of the anxiolytic lorazepam as premedication on the quality of postoperative recovery are unknown. To evaluate whether lorazepam as a premedication beneficially affects quality of recovery (primary outcome) and psychological manifestations (secondary outcome) after day-case surgery. A randomised, double-blind, placebo-controlled clinical trial. Single tertiary centre. day-case surgery; age at least 18 years. insufficient knowledge of the Dutch language; intellectual disability; ophthalmology surgery; extracorporeal shock wave lithotripsy; endoscopy; botulinum toxin A treatment; abortion; chronic pain treatment; preceding use of psychopharmaceuticals; contraindication to lorazepam. Lorazepam (1 to 1.5 mg) intravenously vs. NaCl 0.9% as a premedication prior to surgery. Quality of Recovery-40 (QoR-40) score. State-Trait Anxiety Inventory (STAI-State/Trait); State-Trait Anger Scale (STAS-State/Trait); Multidimensional Fatigue Inventory (MFI); Hospital Anxiety and Depression Scale (HADS). Timing of evaluation: T0: preoperatively (all scales); T1: before discharge (STAI-State/Trait); T2: first postoperative working day (QoR-40); T3: 7th day after surgery (all scales). Robust regression analysis was applied. Statistical analyses were adjusted for the corresponding baseline value and sex. Four hundred patients were randomised; 398 patients were analysed. Postoperative mean QoR-40 scores were similar in both groups at T2 (174.5 vs. 176.4, P = 0.34) and T3 (172.8 vs.176.3, P = 0.38). Postoperative mean STAI-State/Trait scores decreased less in the group with lorazepam at T1 (32.3 vs. 29.3, P < 0.0001; 32.7 vs. 30.8, P = 0.0002). STAI-Trait and HADS-Anxiety decreased less in the group with lorazepam at T3 (31.1 vs. 30.0; P = 0.03, 3.3 vs. 2.5, P = 0.003). STAS-State increased in the group with lorazepam at T3 (10.8 vs. 10.3, P = 0.04). In day-case surgery, lorazepam as a premedication did not improve quality of recovery. Furthermore, this premedication may delay the decrease in postoperative anxiety and aggression. ClinicalTrials.gov identifier: NCT01441843.

Incision length for kidney transplantation does not influence short‐ or long‐term outcome: a prospective randomized controlled trial

While previous studies suggest advantages of minimally invasive surgery in living donor nephrectomy, similar data are lacking for kidney transplant recipients. Our aim was to prospectively evaluate short- and long-term outcome for kidney transplant recipients, comparing a short transverse (ST) to a classical hockey-stick (HS) incision. Sixty-six patients were randomized into two groups: ST vs. HS from January 2008 to May 2010. ST was defined as incision length ≤9 cm and HS as >14 cm. Perioperative data were collected, with evaluation of intra- and postoperative complications and quality of recovery (QoR) score. There were no significant differences in patient demographics, early or long-term postoperative pain. There were no significant differences in QoR scores between the ST and HS group. Predictive for a worse QoR was persisting incisional pain at the 30-month follow-up. Thirty-days mortality, morbidity, and long-term kidney function did not differ between the two groups (p = 1.00, p = 0.62 and p = 0.66, respectively). Patient satisfaction as well as graft function and patient mortality was not influenced by incision length. With patient and graft safety being paramount, especially in times of organ shortage, incision length should reflect the requirement for a successful transplantation and not be a measure of feasibility.

Development and Psychometric Evaluation of a Postoperative Quality of Recovery Score

Quality of recovery (QoR) after anesthesia is an important measure of the early postoperative health status of patients. The aim was to develop a short-form postoperative QoR score, and test its validity, reliability, responsiveness, and clinical acceptability and feasibility. Based on extensive clinical and research experience with the 40-item QoR-40, the strongest psychometrically performing items from each of the five dimensions of the QoR-40 were selected to create a short-form version, the QoR-15. This was then evaluated in 127 adult patients after general anesthesia and surgery. There was good convergent validity between the QoR-15 and a global QoR visual analog scale (r = 0.68, P < 0.0005). Construct validity was supported by a negative correlation with duration of surgery (r = -0.49, P < 0.0005), time spent in the postanesthesia care unit (r = -0.41, P < 0.0005), and duration of hospital stay (r = -0.53, P < 0.0005). There was also excellent internal consistency (0.85), split-half reliability (0.78), and test-retest reliability (ri = 0.99), all P < 0.0005. Responsiveness was excellent with an effect size of 1.35 and a standardized response mean of 1.04. The mean ± SD time to complete the QoR-15 was 2.4 ± 0.8 min. The QoR-15 provides a valid, extensive, and yet efficient evaluation of postoperative QoR.

Intraoperative haloperidol does not improve quality of recovery and postoperative analgesia

Introduction:Haloperidol has an established role in nausea and vomiting prophylaxis and possible effects on multiple aspects of postoperative recovery including pain and sedation. The purpose of this study was to evaluate the effects of low-dose intraoperative intravenous haloperidol on quality of recovery (QoR) and pain control after general anesthesia and surgery.Methods:Ninety eight American Society of Anesthesiologists (ASA) physical status I-II patients undergoing elective general, gynecologic or orthopedic surgery under general anesthesia were enrolled. Participants were randomly allocated to receive either haloperidol 2 mg or sterile water intravenously after induction of anesthesia. All patients were given elastometric morphine patient-controlled analgesia (PCA) pump for pain control after the surgery. Post-operative QoR was evaluated within 20 min in the recovery room and 6 h post-operatively. Pain intensity and demand for additional analgesic was measured in the 6th post-operative hour.Results:The QoR score in two measurements was not statistically different between the two groups. Haloperidol significantly reduced the nausea in the recovery. The visual analog scale pain score showed that the severity of pain in the haloperidol group was more than the placebo group (4.7 ± 2.4 vs. 3.8 ± 2.5, P = 0.05).Conclusion:Intraoperative small-dose IV haloperidol is effective against post-operative nausea and vomiting with no significant effect on overall QoR. It may also attenuate the analgesic effects of morphine PCA.

Transversus abdominis plane block following abdominally based breast reconstruction: study protocol for a randomized controlled trial

BackgroundBreast reconstruction using the free muscle-sparing transversus abdominus myocutaneous or deep inferior epigastric perforator flaps are common methods for restoring mastectomy defects for breast cancer patients. Despite its increasing popularity and safety, the abdominal donor site remains a major source of postoperative pain. Conventional postoperative pain relief protocol consists primarily of a patient-controlled anesthesia device delivering intravenous opioids. Opioids can cause numerous side effects such as sedation, headache, nausea, vomiting, breathing difficulties and bladder and bowel dysfunction. A promising approach to provide postoperative pain control of the abdominal incision is the newly developed transversus abdominis plane peripheral nerve block.Methods/DesignThis study is a double-blind, placebo-controlled, randomized controlled trial designed to rigorously test the effectiveness of a transversus abdominis plane catheter delivering intermittent local anesthetic in reducing postoperative abdominal pain following abdominal tissue breast reconstruction. The primary objective of this study is compare the mean total opioid consumption in the first postoperative 48 hours between the control and study groups including the patient-controlled anesthesia amounts and oral narcotic doses converted to intravenous morphine equivalent units. The secondary outcome measures include the following parameters: total in-hospital cumulative opioid consumption; daily patient-reported pain scores; total in-hospital cumulative anti-nausea consumption; nausea and sedation scores; and Quality of Recovery score; time to first bowel movement, ambulation, and duration of hospital stay.DiscussionAutologous breast reconstruction using abdominal tissue is rapidly becoming the reconstructive option of choice for postmastectomy patients across North America. A substantial component of the pain experienced by patients after this abdominally based procedure is derived from the abdominal wall incision. By potentially decreasing the need for systemic opioids and their associated side effects, this transversus abdominis plane block study will utilize the most scientifically rigorous double-blind, placebo-controlled, randomized controlled trial methodology to potentially improve both clinical care and health outcomes in breast cancer surgery patients.Trial registrationClinicaltrials.gov NCT01398982

The Effect of Hair Colour on Anaesthetic Requirements and Recovery Time after Surgery

Patients with red hair are much more likely to have a variant of the melanocortin-1 receptor gene and this may affect sensitivity to general anaesthetics and pain response. We did a prospective, matched cohort study of 468 healthy adult patients undergoing general anaesthesia for elective surgery. All patients received an inhalational general anaesthetic. Anaesthetic drugs and doses used, hypnotic depth, recovery times, pain scores and quality of recovery scores were recorded. More men than women had red hair, so we did subgroup and multivariable analyses to account for this imbalance. There was no significant difference in recovery times, pain scores or quality of recovery scores in those with red hair. After adjusting for age, sex, American Society of Anesthesiologists physical status and duration of surgery, the recovery ratio for time to eye-opening in redheads was comparable to those with black or brown hair, 0.82 (0.57-1.19), P=0.30. We found no evidence that patient hair colour affects anaesthetic requirements or recovery characteristics in a broad range of surgical procedures.

The cost-effectiveness of an outpatient anesthesia consultation clinic before surgery: a matched Hong Kong cohort study.

BackgroundOutpatient anesthesia clinics are well established in North America, Europe and Australia, but few economic evaluations have been published. The Perioperative Systems in Hong Kong are best described as a hybrid model of the new and old systems of surgical care. In this matched cohort study, we compared the costs and effects of an outpatient anesthesia clinic (OPAC) with the conventional system of admitting patients to the ward a day before surgery for their pre-anesthesia consultation. A second objective of the study was to determine the patient’s median Willingness To Pay (WTP) value for an OPAC.MethodsA total of 352 patients were matched (1:1) on their elective surgical procedure to either the clinic group or to the conventional group. The primary outcome was quality of recovery score and overall perioperative treatment cost (US$). To detect a difference in the joint cost-effect relationship between groups, a cost-effectiveness acceptability curve (CEAC) was drawn. A modified Poisson regression model was used to examine the factors associated with patients willing to pay more than the median WTP value for an OPAC.ResultsThe quality of recovery scores on the first day after surgery between the clinic and conventional groups were similar (mean difference, -0.1; 95% confidence interval (CI), -0.6 to 0.3; P = 0.57). Although the preoperative costs were less in the clinic group (mean difference, -$463, 95% CI, -$648 to -$278 per patient; P <0.001), the total perioperative cost was similar between groups (mean difference, -$172; 95% CI, -$684 to $340 per patient; P = 0.51). The CEAC showed that we could not be 95% confident that the clinic was cost-effective. Compared to the conventional group, clinic patients were three times more likely to prefer OPAC care (relative risk (RR) 2.75, 95% CI, 2.13 to 3.55; P <0.001) and pay more than the median WTP (US$13) for a clinic consultation (RR 3.27, 95% CI, 2.32 to 4.64; P <0.001).ConclusionsThere is uncertainty about the cost-effectiveness of an OPAC in the Hong Kong setting. Most clinic patients were willing to pay a small amount for an anesthesia clinic consultation.

Comparison between intravenous and thoracic epidural analgesia in single coronary artery bypass graft surgery

Aim: To compare thoracic epidural analgesia with intravenous analgesia in patients who underwent coronary artery bypass grafting surgery. Materials and methods: This retrospective study included 40 patients who had received elective single artery bypass surgery. After general anesthesia, one group was given patient-controlled thoracic epidural analgesia and the other group was given patient-controlled intravenous meperidine analgesia. Patient assessments were performed during the postoperative period and included the duration of hospital stay, pain and sedation scores, ambulation score, atrial fibrillation incidence, and organ morbidities. Results: No differences were detected between the groups in the demographic or intraoperative data. However, a statistically significant difference was detected in favor of thoracic epidural analgesia for the duration of extubation and hospital stay, pain control, sedation grade, mobilization, and quality of recovery scores. Conclusion: After single coronary artery surgery, thoracic epidural analgesia was more effective than intravenous analgesia; it also enabled earlier tracheal extubation and a shorter hospitalization period.

A Dose-Ranging Study of the Effect of Transversus Abdominis Block on Postoperative Quality of Recovery and Analgesia After Outpatient Laparoscopy

Postoperative pain can delay functional recovery after outpatient surgery. Multimodal analgesia can improve pain and possibly improve quality of recovery. In this study, we evaluated the dose-dependent effects of a preoperative transversus abdominis plane (TAP) block on patient recovery using the Quality of Recovery 40 (QoR-40) questionnaire after ambulatory gynecological laparoscopic surgery. Global QoR-40 scores range from 40 to 200, representing very poor to outstanding quality of recovery, respectively. Healthy women undergoing outpatient gynecological laparoscopy were randomly allocated to receive a preoperative TAP block using saline, ropivacaine 0.25%, or ropivacaine 0.5%. Needle placement for the TAP blocks was performed using ultrasound guidance and 15 mL of the study solution was injected bilaterally by a blinded investigator. QoR-40 score and analgesic use were assessed 24 hours postoperatively. The primary outcome was global QoR-40 score at 24 hours after surgery. Data were analyzed using the Kruskal-Wallis test. Post hoc pairwise comparisons were made using the Dunn test with P values and 95% confidence intervals Bonferroni corrected for 6 comparisons. Seventy-five subjects were enrolled and 70 subjects completed the study. The median (range) for the QoR-40 score after the TAP block was 157 (127-193), 173 (133-195), and 172 (130-196) for the saline group and 0.25% and 0.5% ropivacaine groups, respectively. The median difference (99.2% confidence interval) in QoR-40 score for 0.5% bupivacaine (16 [1-30], P=0.03) and 0.25% bupivacaine (17 [2-31], P=0.01) was more than saline but not significantly different between ropivacaine groups (-1 [-16 to 12], P=1.0). Increased global QoR-40 scores correlated with decreased area under the pain score time curve during postanesthesia recovery room stay (ρ=-0.56, 99.2% upper confidence limit [UCL]=-0.28), 24-hour opioid consumption (ρ=-0.61, 99.2% UCL=-0.34), pain score (0-10 scale) at 24 hours (ρ=-0.53, 99.2% UCL=-0.25), and time to discharge readiness (ρ=-0.65, 99.2% UCL=-0.42). The aforementioned variables were lower in the TAP block groups receiving ropivacaine compared with saline. The TAP block is an effective adjunct in a multimodal analgesic strategy for ambulatory laparoscopic procedures. TAP blocks with ropivacaine 0.25% and 0.5% reduced pain, decreased opioid consumption, and provided earlier discharge readiness that was associated with better quality of recovery.

The Effect of Neuraxial Versus General Anesthesia Techniques on Postoperative Quality of Recovery and Analgesia After Abdominal Hysterectomy

Patients undergoing abdominal hysterectomy often have significant postoperative pain despite the use of concurrent multimodal pain strategies. Neuraxial anesthesia has opioid-sparing effects and may provide better postoperative recovery to patients when compared with general anesthesia. Our main objective in this study was to compare the effects of neuraxial and general anesthesia on postoperative quality of recovery after abdominal hysterectomy. The study was a prospective, randomized, controlled clinical trial. Seventy healthy females were recruited and randomized to a general anesthesia or neuraxial technique as their primary anesthetic regimen. The primary outcome was the global quality of recovery-40 questionnaire (QoR-40) at 24 hours after the surgical procedure. Other data collected included postoperative pain scores and opioid consumption. Data were analyzed using the Mann-Whitney U test, Fisher's exact test, and linear regression. A P value <0.05 was considered statistically significant. The median difference (95% confidence interval [CI]) in the global QoR-40 score at 24 hours between the neuraxial and general anesthesia groups was 17 (11 to 21.5) (P < 0.001). Patients in the neuraxial anesthesia group had better quality of recovery scores in all the QoR-40 subcomponents than did the general anesthesia group (all P < 0.005). The median difference in global QoR-40 scores at 48 hours between the neuraxial anesthesia and the general anesthesia groups was 8 (6-10) (P < 0.001). Postoperative opioid consumption and pain scores were higher in the general anesthesia group than in the neuraxial anesthesia group. There was an inverse linear relationship between opioid consumption and postoperative quality of recovery at 24 hours, r(2) = 0.67 (P < 0.0001, 95% CI of 0.77 to 0.51), and at 48 hours, r(2) = 0.58 (P < 0.0001, 95% CI of 0.72 to 0.42). Neuraxial anesthesia provides better quality of recovery than does general anesthesia for patients undergoing abdominal hysterectomy. The opioid-sparing effects of neuraxial anesthesia were associated with a better quality of recovery in patients after the surgical procedure. In the absence of contraindications, neuraxial anesthesia seems to be a better anesthetic plan for those patients.

The effect on improvement of recovery and pain scores of paravertebral block immediately before breast surgery

Objectives Paravertebral block (PVB) has the potential to reduce postoperative pain after breast surgery. The aim of the study was to investigate whether PVB performed immediately before surgery could affect the postoperative morbidities in terms of pain and emesis, and improve the quality of recovery (QoR) in patients after surgery for breast cancer. Methods Postoperative data were collected prospectively from two groups of patients undergoing unilateral breast surgery during the study period of 1 month. Forty consecutive patients received either solely general anesthesia (GA group, n = 25) or GA plus ultrasound-guided PVB (GA + PVB group, n = 15) for the surgery. Pain scores and areal distribution of pain were compared between the two groups 1 hour and 6 hours postoperatively and on the midmorning of postoperative Day 1 (POD1). The QoR scores were compared between the two groups 6 hours postoperatively and on the midmorning of POD1. Incidence of postoperative nausea and vomiting and doses of analgesics and narcotics given were also compared. Results Pain scores at rest were significantly lower in the GA + PVB group at all designated time points [1 hour ( p < 0.0001), 6 hours ( p < 0.0001), and on midmorning of POD1 ( p = 0.041)]. Pain scores with movements was also significantly lower at all time points in the GA + PVB group (1 hour, p < 0.0001; 6 hours, p < 0.0001; midmorning of POD1, p = 0.0012). Areal distribution of pain at rest and with movement was wider in the GA group 1 hour and 6 hours postoperately but was identical to that of GA+ PVB group on the mid-morning of POD1 [1 hour postoperatively at rest ( p < 0.0001), with movement ( p < 0.0001); 6 hours postoperatively at rest ( p = 0.0018), with movement ( p = 0.0048)]. The QoR scores were significantly higher in the GA + PVB group at 6 hours ( p < 0.0001) and on midmorning of POD1 ( p = 0.0079). The incidences of postoperative nausea and vomiting were significantly lower in the GA + PVB group ( p = 0.0004). Doses of postoperative analgesics and narcotics were significantly less in the GA + PVB group ( p < 0.0001 and p = 0.001, respectively). Time to first request for analgesics was significantly longer in the GA + PVB group ( p = 0.0002). Conclusions PVB given before surgery in combination with GA could provide better postoperative analgesia and better QoR than did GA alone in patients undergoing surgery for unilateral breast cancer.

Anxiety and quality of recovery in day surgery: A questionnaire study using Hospital Anxiety and Depression Scale and Quality of Recovery Score

The aims of this study were (i) to examine the association between preoperative and postoperative anxiety, and (ii) to examine the association between preoperative anxiety and postoperative recovery, following day surgery under general anaesthesia. Day surgery has become more commonplace owing to advances in pharmacology, anaesthetic and surgical techniques, as it has recognized benefits, such as lower costs and reduced incidence of infection. Recent years have seen increased complexity of day surgery undertaken on a broader range of patients, but with reduced pre-surgery contact with the hospital environment. These recent service changes might have had an effect on the preparation of patients for day surgery, and this in turn might have affected their postoperative recovery. This pilot study used survey methods to examine potential associations between preoperative and postoperative anxiety, and between preoperative anxiety and postoperative recovery. Data were collected in 2008 from a convenience sample of 54 day surgery patients. The instruments used were the Hospital Anxiety and Depression Scale (HADS) and the Quality of Recovery Score (QoR-40). There was a statistically significant relationship between preoperative and postoperative anxiety (χ(2) =11.899, d.f.=1, P=0.001). The T-test showed a statistically significant difference in the mean scores for QoR-40 score for gender, and for the postoperative anxiety and QoR-40. A relationship between preoperative anxiety and postoperative recovery was not shown. Although challenging to implement in view of restricted timescales, appraisal and revision of pre-assessment processes to incorporate an anxiety measurement tool, such as the HADS, should be considered.
