Preoperative intravenous ibuprofen does not influence postoperative narcotic use in patients undergoing elective hernia repair: a randomized, double-blind, placebo controlled prospective trial

IntroductionInguinal and umbilical hernia repairs are among the most common surgical procedures performed in the US. Optimal perioperative pain control regimens remain challenging and opioid analgesics are commonly used. Preoperative nonsteroidal anti-inflammatory drug (NSAID) administration has been shown to reduce postoperative narcotic requirements. This study sought to evaluate the efficacy of perioperative intravenous (IV) ibuprofen on postoperative pain level and narcotic use in patients undergoing open or laparoscopic inguinal and/or umbilical hernia repair.MethodsA single center, randomized, double-blind placebo-controlled trial involving patients ≥18 years undergoing inguinal and/or umbilical hernia repair was performed. Patients were randomized to receive 800 mg of IV ibuprofen or placebo preoperatively. Outcomes assessed included postoperative pain medication required and visual analog scale (VAS) pain scores.ResultsForty-eight adult male patients underwent inguinal and/or umbilical hernia repair. Patients receiving IV ibuprofen used more oxycodone/acetaminophen (32% vs 13%) and IV hydromorphone (12% vs 8.7%), and fewer combinations of pain medications (44% vs 65.2%) in the first two postoperative hours compared to placebo (p=0.556). The IV ibuprofen group had more patients pain free (28% vs 8.7%, p=0.087) and lower VAS scores (3.08±2.14 vs 3.95±1.54, p=0.134) at 2 hours postoperatively, compared to the placebo group, however, this was not statistically significant. Similar pain levels at 1, 3, and 7 days, postoperative and similar use of rescue medications in both groups were observed.ConclusionPreoperative administration of IV ibuprofen did not significantly reduce postoperative pain among patients undergoing elective hernia repair. Considerable variability in postoperative narcotic analgesic requirement was noted, and larger scale studies are needed to better understand the narcotic analgesic requirements associated with IV ibuprofen in inguinal/umbilical hernia repair patients.

Perioperative neutrophil:lymphocyte ratio and postoperative NSAID use as predictors of survival after lung cancer surgery: a retrospective study

The association between neutrophil:lymphocyte ratio (NLR) and poor long-term outcomes in patients with non–small-cell lung cancer (NSCLC) has been demonstrated in numerous studies. The benefit of perioperative administration of anti-inflammatory drugs on these outcomes has not been well established. Our aim in this retrospective study was to investigate the effects of postoperative nonsteroidal anti-inflammatory drug (NSAID) administration and NLR on tumor recurrence and survival in patients' undergoing surgical resection for NSCLC. This retrospective study included perioperative data from 1139 patients who underwent surgical resection for stages I–III NSCLC. Perioperative data such as baseline characteristics, adjuvant or neoadjuvant therapy, pre- and postoperative NLR, and NSAID use (ketorolac, ibuprofen, celecoxib, or in combination) were included. We evaluated the association between preoperative NLR and NSAID use on recurrence-free (RFS) and overall survival (OS). In all, 563 patients received an NSAID as a part of their postoperative management. The majority of patients received ketorolac (n = 374, 67.16%). Ketorolac administration was marginally associated with better OS (P = 0.05) but not with RFS (P = 0.38). Multivariate analysis (n = 1139) showed that preoperative NLR >5 was associated with a reduction in RFS (hazard ratio [HR] = 1.37; 95% confidence interval [CI] = 1.05–1.78; P = 0.02) and OS (HR = 1.69; 95% CI = 1.27–2.23; P = 0.0003). However, after accounting for tumor stage, NLR ≥5 was a predictor of RFS and OS only in patients with stage I NSCLC. To conclude, preoperative NLR was demonstrated to be an independent predictor of RFS and OS in a subset of patients with early stage NSCLC. Ketorolac administration was not found to be an independent predictor of survival.

Treatment of Asherman's syndrome in an outpatient hysteroscopy setting.

To evaluate the feasibility and success rate of treating Asherman syndrome in an outpatient hysteroscopy unit. Retrospective case series (Canadian Task Force classification III). The outpatient hysteroscopy clinic at Ottawa Hospital from November 26, 2008, to January 31,2014. Patients undergoing treatment for Asherman syndrome. All cases of hysteroscopic adhesiolysis were reviewed. Demographic data were collected by a retrospective chart review including patients' age, obstetric history, referring complaint, etiology of Asherman syndrome, antecedent treatment, and outcome measures when available. The severity of Asherman syndrome was determined based on the March classification by the operating surgeon. Analgesia used during the procedure was recorded. Twenty patients were treated for Asherman syndrome in the outpatient hysteroscopy suite. There were a total of 38 procedures (adhesiolysis or diagnostic hysteroscopies) performed for this indication in the patient set. The most common etiologies for intrauterine adhesions were previous curettage (60%) and previous missed abortion (45%). Outcomes were available for 19 patients. All of the patients had normal menses after treatment. Eighty-four percent of patients had either no adhesions or mild adhesions at their final hysteroscopy. Six patients had a spontaneous pregnancy after treatment, and 5 went on to have a term delivery to date. In terms of analgesia used for the procedure, 89% of patients had preoperative nonsteroidal anti-inflammatory drugs, 2.8% required intravenous fentanyl and midazolam, and 5.6% required oral lorazepam. This series showed that Asherman syndrome may be successfully treated in an outpatient hysteroscopy setting outside the operating room and without general or regional anesthesia.

Effects of preoperative non-steroidal anti-inflammatory drugs on pain mitigation and patients' shoulder performance following rotator cuff repair.

Pain is one of the most important factors adversely affecting clinical outcomes of operated patients. The present study aims at evaluating effects of preoperative COX2 non-steroidal anti-inflammatory inhibitors on pain mitigation and performance of patients with shoulder rotator cuff tear. This case-control study was conducted on 60 patients suffering from rotator cuff injury candidate for arthroscopic repair. The patients were classified in two parallel and matched groups. One group (case group) was treated using Celecoxib (200mg/12h) started 48 hours before surgery and continued for 10 days after operation. In the control group, the placebo was prescribed in the same way. Postoperative pain, side effects, sleep disturbance, and short-term outcomes were compared between two groups using DASH questionnaire. Postoperative pain in the Celecoxib group significantly decreased in comparison with the control one. The difference was statistically meaningful (P<0.001). Well motion ability was seen in 80% of patients of the Celecoxib group. It was 26.6% in the placebo group since pain inhibited them from exercising more motions. In this regard, there was a statistically meaningful difference between these two groups (P=0.02). Sleep disturbance was meaningfully at higher levels in the placebo group (P=0.001). Following up the patients for three months, it was made clear that performance of the Celecoxib group was better than that of the placebo one. COX2 inhibitors are well efficient in patients' pain management after arthroscopic rotator cuff repair surgery. It results in less life complications, less sleep disturbances, improvement of patients' short-term clinical outcome, and more quick recovery.

Epidural hematoma after thoracic epidural analgesia in a patient treated with ketorolac, mefenamic acid, and naftazone: a case report.

A 26-year-old male undergoing thoracotomy and bleeding control received a preoperative thoracic epidural for postoperative analgesia. On the fifth postoperative day, paralysis of both lower limbs occurred and urgent magnetic resonance imaging showed massive anterior epidural hematoma. During laminectomy and decompression, platelet dysfunction was diagnosed and preoperative non-steroidal anti-inflammatory drugs medications were supposed to the cause of platelet dysfunction. After infusion of ten units of platelet concentrate, coagulopathy was improved. We should be more careful to drugs with antiplatelet effect when using regional analgesia.

Recent Management Advances in Acute Postoperative Pain

Acute postoperative pain remains a major problem, with both undertreatment and overtreatment leading to serious consequences, including increased risk of persistent postoperative pain, impaired rehabilitation, increased length of stay and/or hospital readmission, and adverse events related to excessive analgesic use, such as oversedation. New analgesic medications and techniques have been introduced that target the preoperative, intraoperative, and postoperative periods to better manage acute postoperative pain, with improvements in analgesic efficacy and safety over more traditional pain management approaches. This review provides an overview of these new analgesic medications and techniques. Specific topics that are discussed include the use of preoperative nonsteroidal anti-inflammatory drugs, anxiolytics, and anticonvulsants; intraoperative approaches such as neuraxial analgesia, continuous local anesthetic wound infusion, transversus abdominis plane block, extended-release epidural morphine, intravenous acetaminophen, and intravenous ketamine; and postoperative use of intravenous ibuprofen, new opioids (eg, tapentadol) or opioid formulations (morphine-oxycodone), and patient-controlled analgesia. New, targeted, analgesic medications and techniques may provide a safer and more effective approach to the management of acute postoperative pain than traditional approaches such as postoperative oral analgesics.

Downregulation of Prominin 1/CD133 expression in colorectal cancer by NSAIDs following short-term preoperative treatment

Expression of Prominin 1/CD133 is associated with poor prognosis and chemoresistance in several types of solid tumors. The aim of the present study was, therefore, to evaluate Prominin 1/CD133 expression in colorectal carcinoma after short-term preoperative treatment by non-steroidal anti-inflammatory drugs (NSAIDs). Patients aimed at curative operation for colon cancer were randomized to receive NSAIDs (indomethacin 50 mg x2 or celecoxib 100 mg x2) three days preoperatively. Antisecretory prophylaxis (esomeprasol 40 mg x1) was provided to all patients and served as sham intake. CD133 expression in tumor tissue was also assessed in tumors from Dukes' B patients selected for either long or short postoperative survival. No patients received perioperative chemoradiotherapy. Tumor tissue was collected at surgery for quantification of mRNAs (Prom1 and Wnt4) by qPCR. Immunohistochemistry stained for CD133, Ep-CAM, CD34 and CD45. PGE2 content in tumor tissue was determined. Transcript of CD133 in tumor tissue was lower in patients treated with NSAIDs (0.28 ± 0.07 vs. 0.51 ± 0.08; p<0.03) as well as some other stem cell-related transcripts. In treated patients 36% of all tumors stained positive for CD133 compared to 71% in sham-treated control patients (p<0.05). Short survivors with Dukes' B tumors displayed 78% CD133 expression as compared to 33% of tumors in long-term survivors (p<0.002). Tumor tissue PGE(2) content was negatively related to patient survival. Our results show that short-term preoperative NSAID treatment downregulates colon cancer tissue expression of Prominin 1/CD133, a stem cell marker indicative of survival prognosis as confirmed.

Hyperkalemia from preoperative non-steroidal anti-inflammatory drugs and angiotensin II receptor blockers in patients with nephropathy

Hyperkalemia is sometimes life-threatening and is common in patients with severe renal insufficiency [1]. Some medications such as cyclooxygenase (COX-1, COX-2) inhibitors, angiotensin converting enzyme (ACE) inhibitors, and angiotensin II receptor blockers (ARBs) reduce the elimination of renal potassium resulting in hyperkalemia. Non-steroidal anti-inflammatory drugs (NSAIDs) are often prescribed as pain killers but have known adverse effects on kidney function. Thus, the elderly and patients at risk for diabetic nephropathy, long-lasting hypertension, or dehydration are more susceptible to the adverse effects of these drugs [2]. An episode of decreased renal function can be underestimated when the signs are asymptomatic, transitory, and non-anuric. Recently, ARBs have been prescribed in patients with hypertension to maintain appropriate renal perfusion by decreasing the glomerular filtration burden. ARBs protect renal and cardiac function by lowering oxidative stress, which is associated with chronic changes in the kidneys, heart, and blood vessels. However, ARBs decrease renal blood flow and reduce the elimination of potassium through the kidney under relatively dehydrated conditions [3] and a hypertensive state. Oral administration of ARBs in patients with chronic renal failure has resulted in serum potassium increases of up to 2 mEq/L during an operation. Although the patient was not suspected to have diabetic nephropathy because of normal creatinine clearance and negative urine protein, a preoperative ACE inhibitor and ARB prescription could lead to hyperkalemia and an abnormal electrocardiogram during an operation [4]. Dehydration has been discussed as a factor in reducing renal blood flow [5]. Thus, chronic administration of ARBs overlapped on possible preoperative dehydration can affect the elimination of potassium resulting in hyperkalemia. In addition to chronic treatment with an ARB, renal side effects of NSAIDs are relatively common and as prevalent as 5%. NSAIDs affect kidney function in two ways: interstitial nephritis due to an immunological reaction and prerenal failure due to reduced renal plasma flow [2]. Activating the renninangiotensin system to increase glomerular filtration pressure is necessary to maintain sufficient filtration. This physiological mechanism requires sufficient local synthesis of vasodilatory prostaglandins (PGE2, PGI2, PGD2) to counteract the action of angiotensin II on vascular tone. Because NSAIDs inhibit the PG-mediated vasodilation of afferent arterioles and glomerular capillaries, renal blood flow is critically affected in those patients at risk [2]. It is also advisable for anesthesiologists to consider the possibility of renal dysfunction in patients at risk with medication even though there is little chance to identify abnormal signs or abnormal laboratory nephropathy findings. It is more important to perform careful monitoring preoperatively and to evaluate renal function and effective circulatory volume.

Preoperative Nonsteroidal Anti-inflammatory Drug or Steroid and Outcomes after Trabeculectomy: A Randomized Controlled Trial

To investigate the benefit of preoperative treatment with either topical nonsteroidal anti-inflammatory drug (NSAID) or steroid in terms of clinical outcomes following trabeculectomy.Prospective, randomized placebo-controlled trial.Sixty-one patients.Between July 2005 and October 2007, 61 consecutive medically uncontrolled glaucoma patients scheduled for first-time trabeculectomy were randomized to 1 of 3 study topical medication groups: nonsteroidal anti-inflammatory drugs (ketorolac), steroids (fluorometholone), or placebo (artificial tears). Patients instilled 1 drop 4 times daily for 1 month before the procedure and were examined on days 1 and 2, at weeks 1, 2, and 4, and at months 3, 6, 12, 18, and 24 after trabeculectomy.Incidence of postoperative surgical or medical interventions (needling, laser suture lysis, needling revision, and intraocular pressure [IOP]-lowering medication).Fifty-four patients (54 eyes) were entered for analysis. The mean number of preoperative medications was 2.3+/-0.9. The mean baseline IOP was 21.0+/-6.0 mmHg. The mean postoperative target IOP was 16.5+/-1.8 mmHg. The mean follow-up was 23.6+/-4.0 months. The percentage of patients requiring needling within the first year was 41% in the placebo group, 6% in the NSAID, and 5% in the steroid group (P = 0.006). The percentage of patients requiring IOP-lowering medication to reach the target IOP at 1 year was 24% in the placebo group, 18% in the NSAID group, and 0% in the steroid group (P = 0.054 overall; P = 0.038 for steroids vs. others). The log-rank test showed a significant (P = 0.019) difference in medication-free survival curves between the different groups. More specifically, patients in the steroid group needed significantly less medication over the total follow-up (P = 0.007).Topical ketorolac or fluorometholone for 1 month before surgery was associated with improved trabeculectomy outcomes in terms of likelihood of postoperative needling. In the steroid group, there was a significantly reduced need for additional postoperative IOP-lowering medication compared with the other groups.The author(s) have no proprietary or commercial interest in any materials discussed in this article.

Prospective, Double-Blinded, Randomized, Placebo-Controlled Comparison of Local Anesthetic and Nonsteroidal Anti-Inflammatory Drugs for Postoperative Pain Management after Laparoscopic Surgery

Compared with the open approach, laparoscopy has been shown to significantly reduce postoperative pain. Improving postoperative analgesia in laparoscopic surgery is an area of continued interest. The goal of this study was to compare the efficacy of local anesthetic infiltration with or without preoperative nonsteroidal anti-inflammatory drugs. Patients undergoing elective laparoscopic cholecystectomy were enrolled in an Institutional Review Board-approved, prospective, double-blinded, randomized, placebo-controlled comparison study. Patients were randomized into four groups: Group I, preoperative oral administration of a placebo medication and preincision local infiltration of 40 mL of 0.5 per cent bupivicaine at trocar sites; Group II, preoperative oral administration of 50 mg of rofecoxib; Group III, preoperative oral administration of 50 mg of rofecoxib and preincision local infiltration of 40 mL of 0.5 per cent bupivicaine into skin, muscle, and peritoneum; and Group IV, preoperative oral administration of a placebo medication. Postoperative pain scores were assessed at 4 hours, 8 hours, 12 hours, and 24 hours using a visual analog scale. Postoperative analgesic use, complications, and length of stay were recorded. Statistical significance was defined as P < 0.05. Fifty-five patients (46 women and 9 men) were enrolled in this study and underwent a standardized, elective, laparoscopic cholecystectomy for mild, symptomatic cholelithiasis (96.4%) and gallbladder polyps (3.6%). No patient had pain immediately before surgery. Postoperative analgesic requests, visual analog scale results, incidence of postoperative vomiting at 4 hours, 8 hours, 12 hours, and 24 hours, in addition to length of stay, were not statistically different between the four groups. No complications occurred. The use of preoperative rofecoxib, 0.5 per cent bupivicaine infiltration, or both for postoperative analgesia did not decrease postoperative pain or decrease length of stay after laparoscopic cholecystectomy compared with placebo. Preoperative administration of an oral anti-inflammatory pain medication, infiltration of a local anesthetic, or both had no greater effect than placebo in controlling discomfort after a laparoscopic cholecystectomy. The challenge of preempting postoperative pain continues and will require further investigation.

No analgesic effect of ibuprofen or paracetamol vs placebo for hysterectomies

The aim of the present study was to evaluate the postoperative opioid-sparing effect of a pre-operative nonsteroidal anti-inflammatory drug (NSAID) (ibuprofen) vs paracetamol in a prospective, double-blind, placebo-controlled study. It was also investigated whether the use of ibuprofen or paracetamol would influence the amount of surgical bleeding. Sixty-six women scheduled for elective open hysterectomy were randomized into one of three groups. All patients received premeditation (diazepam 10 mg) and test drugs orally 1 h before the start of anaesthesia: Group 1 ( n = 23) received 800 mg ibuprofen; Group 2 ( n = 22) received 1000 mg paracetamol; and Group 3 ( n = 21) received placebo. General anaesthesia was given with thiopentone-fentanyl-atracurium induction, and maintained with nitrous oxide-isoflurane. Postoperatively, the patients were evaluated hourly during the recovery period, and 1 and 4 days after the procedure. Postoperative pain was measured by visual analogue scale (VAS), verbal pain score and the need of standardized opioid rescue medication. Intra-operative bleeding was measured, as well as reduction in blood haemoglobin content 24 h and 4 days after the procedure. No differences were found between the groups in postoperative pain measured by any variable or opioid consumption at any time. The amount of surgical bleeding was equal in the three groups. Ibuprofen or paracetamol given pre-operatively to hysterectomy patients do not have a postoperative analgesic or opioid-sparing effect. Perioperative surgical bleeding is not influenced by these drugs.

Increased blood loss after preoperative NSAID. Retrospective study of 186 hip arthroplasties.

We have evaluated bleeding during and after hip replacement in 186 patients in relation to preoperative intake of nonsteroidal anti-inflammatory drugs (NSAID) combined with low molecular weight heparin. NSAID was associated with increased preoperative bleeding and blood transfusion requirements.
