Perioperative Management of Extended-Release Buprenorphine: A Narrative Review and Case Series.

Perioperative management of formulations of buprenorphine used for the treatment of opioid use disorder and/or pain are common clinical challenges. Care strategies are increasingly recommending continuation of buprenorphine while administering multimodal analgesia including full agonist opioids. While this "simultaneous strategy" is relatively simple for the shorter-acting sublingual buprenorphine formulation, best practices are needed for the increasingly prescribed extended-release buprenorphine (ER-buprenorphine). To our knowledge there are no prospective data to guide perioperative management of patients on ER-buprenorphine. Herein we provide a narrative review, report on the perioperative experiences of a series of patients maintained on ER-buprenorphine, and propose recommendations for perioperative ER-buprenorphine management based on best evidence, clinical experience, and our judgments. Here we present clinical data describing the perioperative experiences of patients maintained on extended-release buprenorphine who recently underwent a variety of surgeries ranging from outpatient inguinal hernia repair to multiple inpatient surgeries for source control in sepsis, at different medical centers throughout the United States. These patients were identified via an email solicitation to substance use disorder treatment providers throughout a nationwide healthcare system, requesting cases of patients maintained on extended-release buprenorphine who had recently undergone surgery. We report here on all of the cases received. Extrapolating from these and recently published case reports, we describe an approach to perioperative management of extended-release buprenorphine.

Optimal Timing of Inguinal Hernia Repair in Premature Infants: A NSQIP-P Study

IntroductionAmong premature infants, the incidence of inguinal hernias is reported to be as high as 30%. Despite being one of the most commonly performed procedures, the optimal setting of inguinal hernia repair (IHR) that is inpatient versus outpatient remains debatable. We sought to compare the 30-day outcomes of each approach by querying the National Surgical Quality Improvement Program-Pediatric database. Materials and methodsA retrospective cohort study comparing inpatient versus outpatient IHR using the National Surgical Quality Improvement Program-Pediatric database from 2013 to 2019 was performed. Demographic and clinical data were initially compared using univariate analysis. Continuous variables are presented as median and interquartile range and categorical variables are presented as n (%). Subsequently, cohorts were propensity matched using clinically and statistically significant patient characteristics. Results928 patients underwent IHR, 634 (68.3%) while inpatient, 294 (31.7%) following hospital discharge. Inpatient IHR was associated with lower age at the time of surgery (120 versus 147 d; P < 0.0001), younger gestational age (27 versus 33 wk; P < 0.0001), decreased probability of repair in elective setting (87.2% versus 97.3%; P < 0.0001), and increased preoperative supplemental oxygen need (42% versus 4.4%; P < 0.0001). Comparison of propensity matched cohorts revealed that inpatient IHR was associated with increased procedure time (82 versus 51 min; P < 0.0001) and anesthetic duration (146 versus 102 min; P < 0.0001), wound infection rates (3.8% versus 0%; P = 0.007), blood transfusions (4.2% versus 0.5%; P = 0.036), unplanned intubations (2.8% versus 0%; P = 0.03), ventilator days (0 versus 0; range [0,30 versus 0,2]; P = 0.002), reoperation rate (5.6% versus 0%; P < 0.001), postoperative hospital length of stay (4 versus 1 d; P < 0.0001), and unplanned readmissions (8.9% versus 0.9%; P = 0.002). ConclusionsInpatient IHR in premature neonates were associated with different postoperative outcomes than outpatient IHR. At least in the elective setting among premature infants, outpatient IHR can be considered safe in select patients while we await higher quality prospective data.

Outpatient inguinal hernia repair in Spain: a population-based study of 1,163,039 patients—clinical and socioeconomic factors associated with the choice of day surgery

Reducing inpatient admissions and health care costs is a central aspiration of worldwide health systems. This study aimed to evaluate trends in outpatient surgery in inguinal hernia repair (IHR) and factors related to the outpatient setting in Spain. A retrospective cohort study (Record-Strobe compliant) of 1,163,039 patients who underwent IHR from January 2004 to December 2019 was conducted. Data were extracted from the public clinical administrative database CMBD (“Conjunto Mínimo Básico de Datos”). The primary outcome was the outpatient surgery rate. Univariate and multivariable analyses were performed to identify clinical and socioeconomic factors related to the outpatient setting. The overall proportion of outpatient repairs was 30.7% in 2004 and 54.2% in 2019 (p < 0.001). Treatment in a public hospital was the most remarkable factor associated with the likelihood of receiving an outpatient procedure (OR 3.408; p < 0.001). There were also significant differences favouring outpatient procedures for patients with public insurance (OR 2.351; p < 0.001), unilateral hernia (OR 2.903; p < 0.001), primary hernia (OR 1.937; p < 0.0005), age < 65 years (OR 1.747; p < 0.001) and open surgery (OR 1.610; p < 0.001). Only 9% of patients who pay for their intervention privately or 15% of those covered by private insurance were treated as outpatients. Spain has significantly increased the rate of outpatient IHR over the last 16 years. However, the figures obtained still leave a significant margin for improvement. Important questions about the acceptance of outpatient settings remain to be answered.Graphical Outpatient inguinal hernia repair in Spain.

Analysis of temporal trends in robotic surgery costs using the outpatient inguinal hernia repair model

BackgroundRobotic technology is increasingly utilized despite increased costs compared with laparoscopic procedures. As the robot is a fixed, indirect cost, we hypothesized increased volume of robotic procedures will decrease operative costs per patient. The model of same-day, unilateral, primary inguinal hernia surgery in males was chosen. MethodsThe Florida Agency for Health Care Administration database was queried for inguinal hernia repairs from 2015 to 2020. Inflation adjusted total and operative costs per patient were collected. Cost-over-time and change in cost-over-time were calculated for open, laparoscopic, and robotic cases. Linear regression using cost as the dependent variable generated predictive parameters. ResultsIn the study, 36,393 cases (19,364 open, 12,322 laparoscopic, 4,707 robotic) among 86 hospitals were included. In addition, 18 hospitals were “high volume,” defined as total robotic inguinal hernia volume of >100 (range, 107-368) during the study period, and included 8,604 cases (3,915 open, 1,786 laparoscopic, 2,903 robotic). Compared with laparoscopic, total robotic cost and cost over time were 1.22- (P < .001) and 1.5-fold higher (P < .002). The change in cost-over-time was increased significantly in robotic cases: 358, 420, 548, 691, and 1,542 cost-over-time for 2015 to 2020, respectively. Positive contributors to total hospital robotic costs were total robotic inguinal hernia volume (17.3), total laparoscopic inguinal hernia volume (12.6), and number of hospital beds (1.9). Total open inguinal hernia volume was a negative contributor (–10). ConclusionWe conclude, in the short term, robotic surgical costs are not behaving as traditional fixed costs in outpatient, unilateral inguinal hernia surgeries. Hospital methodology for cost assignment and increased robotic fixed costs such as purchase of additional instruments may explain these results.

Morbid Obesity Not a Risk for Serious Complications Following Outpatient Surgery.

Patients with class III obesity are often excluded from surgery in ambulatory surgery centers (ASCs). We hypothesize that class III obesity is not a risk factor for serious post-operative complications following outpatient operations. ACS-NSQIP database from 2012 to 2018 was queried. Patients undergoing outpatient inguinal hernia repair (IHR) and laparoscopic cholecystectomy (LC) were grouped by BMI. Baseline characteristics and 30-day outcomes were compared using univariate and multivariate analyses. Of these, 79,916 patients underwent IHR and 107,471 patients underwent LC. Multivariable analysis in IHR showed increased odds of superficial SSIs in all classes of obesity compared to normal weight (P < .0001). In the LC group, there were higher rates of SSIs with obesity (P < .0001). For both surgeries, a higher rate of readmissions to the hospital were observed in class II and IIIa obesity (both P < .0001), although rates were relatively low (<3%). Class III obesity demonstrates a statistically significant increase in SSI following IHR and LC. Severe complications requiring readmission are not mirrored, suggesting the morbidly obese patients should be considered for routine surgical procedures in outpatient settings.

Phone follow-up after inguinal hernia repair.

BackgroundTypically, in-person follow-up in clinic is utilized after outpatient inguinal hernia repair. Studies have shown that phone follow-up may be successfully used for the detection of postoperative hernia recurrences. However, no studies have evaluated the detection rates of other postoperative complications, such as emergency department visits and readmissions, with the utilization of phone follow-up after inguinal hernia repair. The objective of our study was to investigate the safety of a phone follow-up care pathway following elective, outpatient inguinal hernia repair.MethodsIn this retrospective cohort study, adult patients who underwent elective, outpatient inguinal hernia repair between 2013 and 2019 at a large academic health system in the Midwest United States were identified from the electronic health record. Patients were categorized by type of postoperative follow-up: in-person or phone follow-up. Baseline demographics, operative, and postoperative data were compared between follow-up groups. Multivariable logistic regression was performed to investigate predictors of having any related emergency department (ED) visit/readmission/reoperation within 90 days.ResultsWe included 2009 patients who underwent elective inguinal hernia repair during the study period. 321 patients had in-person follow-up only, while 1,688 patients had phone follow-up. There was a higher rate of laparoscopic repair in the phone follow-up group (85.4% vs. 53.0% for in-person follow-up). There were no differences in rates of related 90-day ED visits, readmissions, and reoperations between the phone and in-person follow-up groups. On multivariable logistic regression, receipt of phone follow-up was not a predictor of having 90-day ED visits, readmissions, or reoperations (OR 1.30, 95% CI [0.83, 2.05]).ConclusionsPatients who underwent phone follow-up had similarly low rates of adverse outcomes to those with in-person follow-up. Phone follow-up protocols may be implemented as an alternative for patients and provide a means to decrease healthcare utilization following inguinal hernia repair.Electronic supplementary materialThe online version of this article (10.1007/s00464-020-08005-5) contains supplementary material, which is available to authorized users.

Robotic Approach to Outpatient Inguinal Hernia Repair

Robotics offers improved ergonomics, visualization, instrument articulation, and tremor filtration. Disadvantages include startup cost and system breakdown. Surgeon education notwithstanding, we hypothesize that robotic inguinal hernia repair carries minimal advantages over the laparoscopic or open approach. The 2009-2015 Healthcare Cost and Utilization Project-State Ambulatory Surgery and Services and American Hospital Association Annual Health data sets from Florida were queried for open, laparoscopic, and robotic inguinal hernia repairs. Hospital and patient demographic, financial, and comorbidity data (26 total variables) were evaluated. Data are presented as mean ± SEM; p < 0.05 was considered significant. We identified 103,183 cases (63,375 open, 38,886 laparoscopic, and 922 robotic). Patient characteristics were the following: male, white, aged 51 to 70 years, nongovernmental and not-for-profit hospitals, grouped Charlson Comorbidity Category= 0, private insurance coverage, median income quartile 3 (4= highest), and routine discharge disposition (all, p < 0.05). Total charges were: $18,261 ± $38 (open), $25,223 ± $60 (laparoscopic), and $45,830 ± $1,023 (robot) (p < 0.0001 robot vs open, robot vs laparoscopic, and laparoscopic vs open). Top factors associated with open procedures (area under the curve 0.785): hospital is investor owned for profit, self-pay, black, Latino, and Medicaid; with laparoscopic procedures (area under the curve 0.771): private insurance, median income quartile 4 (highest), median income quartile 3, median income quartile 2, and nongovernmental, not-for-profit hospitals; and with robotic procedures (area under the curve 0.936): Charlson Comorbidity Category= 2, Charlson Comorbidity Category= 1, median income quartile 3, median income quartile 2, and age. Robotic surgery has increased charges and is performed in sicker, higher-income patients. The open approach is more apt to be performed in black/Hispanic, self-pay patients, and for-profit hospitals. The role for robotic inguinal hernia repair is undefined.

Dexmedetomidine as adjunct to ilioinguinal/iliohypogastric nerve blocks for pediatric inguinal hernia repair: an exploratory randomized controlled trial.

Adult meta-analysis has identified dexmedetomidine as a potentially useful adjunct to prolong the duration of peripheral nerve blocks. However, no data exist regarding the adjuvant use of dexmedetomidine in the setting of pediatric peripheral nerve blocks. Using a prospective, randomized, double-blind design, children (1½-8 years, ASA 1-2) scheduled for outpatient inguinal hernia repair were randomized to receive either an ultrasound-guided ilioinguinal/iliohypogastric nerve block (IINB) with plain ropivacaine 0.197% (Group LA; n = 21) or ropivacaine 0.197% with adjunct dexmedetomidine 0.3 μg·kg(-1) (Group LAD; n = 22). The primary endpoint of the study was time to first postoperative administration of supplemental analgesia (FPASA) triggered by a pain score ≥4 (CHIPPS or NRS scale). Intention-to-treat (ITT) analysis was decided as the primary statistical analysis of the data. The median time to FPASA was prolonged by 88% following the use of adjunct dexmedetomidine (4.0 and 7.6 h in group LA and LAD, respectively) (P = 0.0717). Patients in Group LA displayed a significantly higher number of patients with a CHIPPS score ≥4 in the PACU (7 vs 0; P = 0.0029) as well as a higher incidence of PAED (4 vs 0; P = 0.0485) when compared to patients in Group LAD. No adverse events were recorded in any of the study groups. The use of dexmedetomidine as an adjunct to an IINB resulted in reduced incidences of CHIPPS pain scores ≥4 and PAED scores of ≥11 during early recovery following pediatric inguinal hernia repair. In addition, the use of adjunct dexmedetomidine was associated with a prolongation of the period to first supplemental analgesia demand. The results of the present exploratory study must be viewed as preliminary and need further validation by future larger sized studies and/or meta-analysis.

Outcomes and charges associated with outpatient inguinal hernia repair according to method of anesthesia and surgical approach

BackgroundWe conducted this study to compare short-term outcomes and charges between methods of hernia repair and anesthesia in the outpatient setting. MethodsUsing New York's state ambulatory surgery databases, we identified discharges for patients who underwent inguinal hernia repair. Patients were grouped by method of hernia repair. We compared hospital-based acute care encounters and total charges across groups. ResultsLocoregional anesthesia (5.2%) experienced a similar frequency of hospital-based acute care encounters within 30 days of discharge when compared with patients receiving general (6.0%) or having a laparoscopic procedure (6.0%). Risk-adjusted charges increased across groups (locoregional = $6,845 vs general = $7,839 vs laparoscopic = $11,340, P < .01). ConclusionOpen inguinal hernia repair under local anesthesia reduces healthcare charges.

Anestesia subaracnoidea y anestesia general en el tratamiento quirúrgico de la hernia inguinal en pacientes ambulatorios. Análisis comparativo de coste-efectividad

To compare the costs related to the clinical effectiveness of general anesthesia versus spinal anesthesia in inguinal hernioplasty ambulatory surgery. An observational, retrospective cohort study measurement and analysis of cost-effectiveness, in the ambulatory surgery unit of a general hospital. All patients over 18 years of age diagnosed with primary inguinal hernia and scheduled for unilateral hernioplasty between January 2010 and December 2011 were included. Duration of anesthetic induction, length of stay in both the operating room, and in the post-anesthesia care unit, the anesthetic effectiveness (the incidence of adverse effects and the patient's comfort level), and variable economic costs associated with the use of drugs, as well as the use of human resources, were compared. The final analysis included 218 patients, 87.2% male, with a mean age of 53 years (range: 18-85 years). Of these, 139 (63.76%) received subarachnoid anesthesia and 79,(36.2%) general anesthesia. The length of time a patient remained in the post-anesthesia care unit was 337.6±160.2min in the subarachnoid anesthesia group, and 210.0±97.5min for the general anesthesia group (P<.001). Costs of drugs for general anesthesia were higher than that for subarachnoid anesthesia (86.2±8.3 vs. 18.7±7.2). The total cost difference between the 2 techniques was €115.8 more for subarachnoid anesthesia (P<.001). Both techniques showed similar effectiveness. The overall costs for subarachnoid anesthesia were greater than for the general. The cost-effectiveness of general anesthesia is better for outpatient inguinal hernia repair surgery.

Outpatient inguinal hernia repair under local anaesthesia: feasibility and efficacy of ultrasound-guided transversus abdominis plane block

The aim of this prospective randomized study was to determine the utility of transversus abdominis plane (TAP) block to improve the efficacy of conventional local anaesthesia for hernia repair in order to achieve an adequate anaesthesia and to evaluate its post-operative analgesic effectiveness. Hundred and fifty consecutive male patients undergoing outpatient hernia repair (Lichtenstein technique) were enrolled in this study. Patients were randomly allocated to undergo a combined TAP block and local anaesthesia (case group) or single conventional local anaesthesia (control group). The study was designed to obtain a 1:2 case-control ratio. The primary outcome was the evaluation of the proportion of patients achieving an adequate anaesthesia. The secondary outcome was the evaluation of pain on movement, pain at rest, rescue analgesia need, nausea and satisfaction. An adequate anaesthesia was achieved in 8 % case and in 36 % control subjects (p = 0.001). At the 6 and 12 h post-operative evaluations, patients enrolled in the case group reported significantly less pain (evaluated by VAS score) both at rest and on movement (p always = 0.001). Moreover, the need of rescue analgesia resulted significantly higher in the control group (14 vs. 32 %, p = 0.01). Our results demonstrated that, as compared with conventional local anaesthesia, the combination of TAP block with local anaesthesia showed a higher efficacy in the obtainment of an adequate anaesthesia and in the post-operative pain control for hernia repair.

Single Level Paravertebral versus Caudal Block in Paediatric Inguinal Surgery

Paravertebral block (PVB) has been used for postoperative analgesia in children since 1992. There are no prospective randomised studies comparing the use of PVB versus caudal block (CB) for outpatient inguinal hernia repair surgery. The hypothesis of this study is that a single level, single injection PVB can provide a longer duration of analgesia and less requirement for supplemental analgesia than single shot CB for children undergoing inguinal surgery. Seventy children, aged three to seven, American Society of Anesthesiologists score I to II, having unilateral inguinal surgery were enrolled in the study. The patients were divided into two randomised groups. In group PVB, a single shot of 0.2 ml/kg levobupivacaine was administered via the lumbar paravertebral route and in group CB, patients were given 1 ml/kg levobupivacaine caudally. Sevoflurane concentration was evaluated after induction and recorded during incision, sac traction and closure. Face, legs, activity, cry and consolability (FLACC) scores, heart rate, blood pressure and SpO2 were evaluated postoperatively. Only four (11.4%) patients in the PVB group needed rescue analgesic drugs compared to 12 (34.3%) patients in the CB group (P = 0.044). Patients were given tramadol as rescue analgesia in the first four postoperative hours. No other supplemental analgesic drug was given apart from tramadol. FLACC scores were the same in the both groups. Parental satisfaction was significantly higher in the PVB group compared to the CB group (74.3 vs 40%, P = 0.01). This study has demonstrated that a single level single injection paravertebral block provides superior intraoperative and postoperative analgesia when compared to a caudal block for unilateral inguinal hernia repair.

Ultrasound-Guided Transversus Abdominis Plane Catheters and Ambulatory Perineural Infusions for Outpatient Inguinal Hernia Repair

Transversus abdominis plane (TAP) blocks anesthetize the lower abdominal wall, and TAP catheters have been used to provide prolonged postoperative analgesia after laparotomy. The use of TAP catheters on an outpatient basis has not yet been described. We present our experience with ultrasound-guided TAP perineural catheter insertion and subsequent management of ambulatory TAP local anesthetic infusions after inguinal hernia repair. Three patients scheduled for unilateral open inguinal hernia repair underwent preoperative posterior TAP catheter placement for postoperative pain management using a technique employing ultrasound guidance alone. A bolus of local anesthetic solution was injected via the catheter in divided doses, and block onset was confirmed before surgery. Postoperatively, a continuous infusion of ropivacaine 0.2% was delivered using a portable infusion pump, and patients were discharged with a prescription for oral analgesics for breakthrough pain and perineural infusion instructions. Patients were followed up daily by telephone. All patients underwent successful TAP catheter insertion and maintained their catheters until postoperative day 2. All patients reported minimal pain for the duration of infusion without the need for any supplemental opioid analgesics, high satisfaction with postoperative analgesia, and no infusion-related complications. An ultrasound-guided TAP catheter and ambulatory local anesthetic perineural infusion are a promising option for prolonged postoperative analgesia after outpatient inguinal hernia repair. A posterior insertion permits preoperative placement by keeping the catheter away from the planned surgical field.

Fentanyl Sparing Effects of Combined Ketorolac and Acetaminophen for Outpatient Inguinal Hernia Repair in Children

In this prospective, randomized, double-blinded study we sought to evaluate the efficacy and safety of combined use of intravenous ketorolac and acetaminophen in small children undergoing outpatient inguinal hernia repair. We studied 55 children 1 to 5 years old who were undergoing elective repair of unilateral inguinal hernia. After induction of general anesthesia children in the experimental group (28 patients) received 1 mg/kg ketorolac and 20 mg/kg acetaminophen intravenously. In the control group (27 patients) the same volume of saline was administered. All patients received 1 microg/kg fentanyl intravenously before incision. We also evaluated the number of patients requiring postoperative rescue fentanyl, total fentanyl consumption, pain scores and side effects. Significantly fewer patients receiving ketorolac-acetaminophen received postoperative rescue fentanyl compared to controls (28.6% vs 81.5%). A significantly lower total dose of fentanyl was administered to patients receiving ketorolac-acetaminophen compared to controls (0.54 vs 1.37 microg/kg). Pain scores were significantly higher in the control group immediately postoperatively but eventually decreased. The incidences of sedation use (55.6% vs 25.0%) and vomiting (33.3% vs 10.7%) were significantly higher in controls. Preoperative intravenous coadministration of ketorolac and acetaminophen is a simple, safe and effective method for relieving postoperative pain, and demonstrates highly significant fentanyl sparing effects in small children after outpatient inguinal hernia repair.

Three concentrations of levobupivacaine for ilioinguinal/iliohypogastric nerve block in ambulatory pediatric surgery

Study Objective To compare the postoperative analgesia of three different concentrations of levobupivacaine for ilioinguinal/iliohypogastric (II/IH) block in children undergoing inguinal hernia repair. Design Double-blind, prospective, randomized, controlled trial. Setting Operating room and postoperative recovery area of a university hospital. Patients 73 ASA physical status I and II children, aged one to 6 years, scheduled for outpatient inguinal hernia repair. Interventions Patients were randomized to receive one of three levobupivacaine concentrations: 0.125% (L0.125), 0.25% (L0.25), or 0.375% (L0.375). All patients received standard anesthesia with sevoflurane and II/IH nerve block. Measurements Heart rate (HR), non invasive blood pressure (NIBP), respiratory rate, end-tidal carbon dioxide concentration (ETCO 2), and oxygen saturation via pulse oximetry (SpO 2) were monitored during surgery. Postoperative pain scores with CHEOPS (Children's Hospital of Eastern Ontario Pain Scale) and need for rescue analgesia postoperatively were measured and recorded. Main Results 60 patients entered the postoperative observational period. The number of patients who received rescue analgesia was comparable in the three groups. In Group L0.125, mean CHEOPS score was significantly higher, and time to first administration of rescue analgesia was shorter, than in the other two groups ( P < 0.05). Pain scores and time to first administration of rescue analgesia were comparable between Groups L0.25 and L0.375. Conclusions II/IH nerve block using 0.4 mL kg -1 of 0.25% levobupivacaine provided satisfactory postoperative pain relief after inguinal herniorraphy.

A prospective, randomized, comparative trial of a COX-2 selective nonsteroidal anti-inflammatory drug versus placebo in inguinal herniorrhaphy patients

The standard opioid treatment for postoperative pain can be associated with nausea, vomiting, and constipation. In addition, opioids often provide insufficient pain relief. The purpose of this study was to compare postoperative pain and functional outcomes in patients undergoing inguinal herniorrhaphy who receive a COX-2 selective nonsteroidal anti-inflammatory drug (COX-2) or placebo preoperatively and for 4 days postoperatively. A prospective, randomized, blinded, placebo-controlled trial was conducted in adults undergoing elective, outpatient, unilateral inguinal herniorrhaphy. Patients received rofecoxib (50 mg, 1 h prior to incision) or placebo. Doses were re-administered once daily on postoperative days 1-4. Patients were also given hydrocodone bitartrate for use as needed in the postoperative period. Pain outcomes were assessed, including pain intensity (1-10 visual-analogue scale) and the use of hydrocodone bitartrate. In addition, functional outcomes such as activity and return of bowel function were examined for 5 postoperative days. Incidence and severity of side effects were examined. Statistics are mean +/- standard deviation. Fifty-five subjects completed the study. Twenty-six patients received rofecoxib and 29 patients received placebo. Patients who received COX-2 demonstrated improved bowel function as reflected by more bowel movements on postoperative day 2 and postoperative day 3. COX-2-treated patients also reported better oral intake on these same days. In addition, COX-2-treated patients had less difficulty coughing on postoperative day 1. Overall satisfaction with pain management was better in COX-2-treated patients (very satisfied vs. satisfied). There were no statistically significant differences between groups in the amount of hydrocodone bitartrate consumption. There were no complications during the study period. Administration of a COX-2 selective nonsteroidal anti-inflammatory drug prior to and following outpatient inguinal herniorrhaphy improves functional outcomes when compared with placebo and increases patient satisfaction. These results suggest that multimodal pain therapy with COX-2 inhibitors may have a role in outpatient inguinal hernia repair.

Prioritizing Quality Improvement in General Surgery

Despite growing interest in quality improvement, uncertainty remains about which procedures offer the most room for improvement in general surgery. In this context, we sought to describe the relative contribution of different procedures to overall morbidity, mortality, and excess length of stay in general surgery. Using data from the American College of Surgeons' National Surgery Quality Improvement Program (ACS-NSQIP), we identified all patients undergoing a general surgery procedure in 2005 and 2006 (n=129,233). Patients were placed in 36 distinct procedure groups based on Current Procedural Terminology codes. We first examined procedure groups according to their relative contribution to overall morbidity and mortality. We then assessed procedure groups according to their contribution to overall excess length of stay. Ten procedure groups alone accounted for 62% of complications and 54% of excess hospital days. Colectomy accounted for the greatest share of adverse events, followed by small intestine resection, inpatient cholecystectomy, and ventral hernia repair. In contrast, several common procedures contributed little to overall morbidity and mortality. For example, outpatient cholecystectomy, breast procedures, thyroidectomy, parathyroidectomy, and outpatient inguinal hernia repair together accounted for 34% of procedures, but only 6% of complications (and only 4% of major complications). These same procedures accounted for < 1% of excess hospital days. A relatively small number of procedures account for a disproportionate share of the morbidity, mortality, and excess hospital days in general surgery. Focusing quality improvement efforts on these procedures may be an effective strategy for improving patient care and reducing cost.

Preoperative Rofecoxib Plus Local Anesthetic Field Block Diminishes Pain and Recovery Time After Outpatient Inguinal Hernia Repair

Preoperative Rofecoxib Plus Local Anesthetic Field Block Diminishes Pain and Recovery Time After Outpatient Inguinal Hernia Repair

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.

Incidence of persistent pain one year after continuous local anesthetic infusion for postoperative pain following outpatient inguinal herniorrhaphy

The purpose of this study was to determine the presence and severity of persistent pain one year following outpatient inguinal unilateral hernia repair in patients who participated in a prospective, randomized, blinded, placebo-controlled trial of continuous local anesthetic wound infusion.1 Patients received 120 ml of either saline or 0.5% bupivicaine at 2ml(2 mg bupivicaine)/hr through a disposable infusion pump for 60 hours postoperatively. Seventy-two (of original sample of 79; 38 placebo and 34 bupivicaine) patients completed a telephone survey one year following surgery that examined the incidence, severity, and functional interference of persistent pain related to their hernia surgery.
