Abstract Background Multimodal analgesia consists of the combination of analgesic drugs at low doses to act in different places along the path of pain. Studies with continuous infusion of analgesic drugs in cats are not common. This study aimed to evaluate the analgesic effect of maropitant, lidocaine and ketamine alone or in combination (intravenous bolus + subsequent continuous intravenous infusion) in the management of acute postoperative pain in cats undergoing ovariohysterectomy. Seventy healthy cats undergoing an ovariohysterectomy received a standard anesthetic protocol consisting of acepromazine and morphine, propofol (anesthesia induction), and isoflurane (anesthesia maintenance). The animals were stratified into seven groups (n = 10 in each group): control (CG), maropitant (MG), lidocaine (LG), ketamine (KG), maropitant + lidocaine (LMG), maropitant + ketamine (KMG), and maropitant + lidocaine + ketamine (LKMG). All drugs were injected first as an intravenous bolus and then by continuous intravenous infusion. During surgery, esophageal temperature, respiratory rate, heart rate, oxygen saturation, expired isoflurane concentration, and partial pressure of carbon dioxide at the end of expiration were evaluated at 7 time points. Postoperative pain was evaluated for 6 h after extubation using the visual analogue scale and the UNESP-Botucatu multidimensional composite pain scale for assessing postoperative pain in cats. Results Adverse effects related to maropitant, lidocaine and ketamine infusion were not observed. Pain scores were lower in the MG, KG and LG groups when compared to the CG group using both scales. Although pain scores were also lower in all combination groups than CG, more animals in these groups required rescue analgesia compared to MG. This indicates that the postoperative analgesic effect of all drugs, either alone or in combination, confers analgesia, although the combinations did not promote greater analgesia. Conclusions Continuous intravenous infusion of maropitant, lidocaine, and ketamine alone induces postoperative analgesic effect in cats undergoing ovariohysterectomy, but combinations of these drugs did not increase the analgesic effect. No adverse effect was observed with any drug or their combination.

AbstractThe objective of this study was to examine the impact of around-the-clock (ATC) administration of intravenous (IV) acetaminophen following robot-assisted radical prostatectomy (RARP). Intravenous infusion of acetaminophen was started on the day of the operation at 1000 mg/dose every 6 h, and the infusion was continued on a fixed schedule until postoperative day 2 a.m. In a retrospective observational study, we compared 127 patients who were administered IV acetaminophen on a fixed schedule (ATC group) with 485 patients who were administered analgesic drugs only as needed (PRN group). We investigated postoperative pain intensity and additional analgesic consumption on postoperative day 0, 1, 2, 3, and 5 between the two groups. Postoperative pain scores were significantly lower in the ATC group than in the PRN group at 1 and 2 days, and this period matched the duration of ATC administration of IV acetaminophen. Postoperative frequency of rescue analgesia was significantly lower in the ATC group than in the PRN group at postoperative 0, 1, and 2 days. ATC administration of IV acetaminophen has the potential to be a very versatile and valuable additional dose to achieve appropriate postoperative analgesia in patients with RARP.

Abstract Background Well-controlled postoperative pain is essential for early recovery after uniportal video-assisted thoracoscopic surgery (UVATS). Conventional analgesia like opioids and thoracic epidural anaesthesia have been associated with hypotension and urinary retention. Intercostal catheters are a regional analgesic alternative that can be inserted during UVATS to avoid these adverse effects. This feasibility study aims to evaluate the postoperative pain scores and analgesic requirements with incorporation of an intercostal catheter into a multimodal analgesic strategy for UVATS. Methods In this observational study, 26 consecutive patients who underwent UVATS were administered a multilevel intercostal block and oral paracetamol. All of these patients received 0.2% ropivacaine continuously at 4 ml/h via an intercostal catheter at the level of the incision. Rescue analgesia including etoricoxib, gabapentin and opioids were prescribed using a pain ladder approach. Postoperative pain scores and analgesic usage were assessed. The secondary outcomes were postoperative complications, days to ambulation and length of stay. Results No technical difficulties were encountered during placement of the intercostal catheter. There was only one case of peri-catheter leakage. Mean pain score was 0.31 (range 0–2) on post-operative day 1 and was 0.00 by post-operative day 5. 16 patients (61.6%) required only oral rescue analgesia. The number of patients who required rescue non-opioids only increased from 1 in the first 7 months to 8 in the next 7 months. There were no cases of hypotension or urinary retention. Median time to ambulation was 1 day (range 1–2). Mean post-operative length of stay was 4.17 ± 2.50 days. Conclusions Incorporation of an intercostal catheter into a multimodal analgesia strategy for UVATS is feasible and may provide adequate pain control with decreased opioid usage.

Currently most of the anesthetist prefer the usage of multimodal analgesia technique to improve the degree of pain relief without inducing any side effects. Pregabalin and gabapentin when given in higher doses reduces the preoperative anxiety and induce sedation without causing undesirable side effects.To compare and evaluate the effects of premedication drugs Pregabalin or Gabapentin versus placebo for attenuation of postoperative pain among patients undergoing laparoscopic cholecystectomy under general anaesthesia.A prospective comparative study was conducted for a period of 6 months in the department of anesthesiology of our medical college hospital. A total of 90 patients posted for elective laproscopic cholecystectomy in the age group between 20 and 60 years were taken as our study subjects. The entire study subjects were randomized into three groups of 30 each. Group B subjects received 3 tablets of Beplex forte (as placebo), Group G subjects received 3 tablets of Gabapentin 300mg (total 900mg) and Group P subjects received 3 tablets of Pregabalin 50mg (total 150mg). Post-operatively degree of pain, requirement for rescue analgesia, sedation score and adverse events occurred was monitored and analysed between the three groups. Pain score was less in the pregabalin group at all intervals compared to gabapentin and placebo group and the difference was found to be statistically significant. Maximum amount of tramadol requirement as a part of rescue analgesia was seen in the placebo group followed by gabapentin group and minimal dose requirement was needed for pregabalin group and the difference was found to be statistically significant. The occurrence of adverse events such as somnolence and dizziness was almost similar in all the three groups whereas the incidence of nausea and vomiting was less in pregabalin group compared to gabapentin and placebo group. Pregabalin can be effectively used as a part of the multimodal analgesic to prevent acute postoperative pain among patients undergoing elective laproscopic cholecystectomy.

Objectives The aim of this study was to evaluate the analgesic efficacy of oral tramadol in cats undergoing ovariohysterectomy. Methods Twenty-four female domestic cats, American Society of Anesthesiologists class I, aged 4–24 months, were included in this positive controlled, randomised, blinded clinical trial. Cats admitted for ovariohysterectomy were allocated to group oral tramadol (GOT, n = 12) or group intramuscular tramadol (GIMT, n = 12). In GOT, tramadol (6 mg/kg) was given orally 60 mins, and saline was given intramuscularly 30 mins, before induction of anaesthesia. In GIMT, granulated sugar in capsules was given orally 60 mins and tramadol (4 mg/kg) intramuscularly 30 mins before induction of anaesthesia. In both groups, dexmedetomidine (0.007 mg/kg) was given intramuscularly 30 mins before induction of anaesthesia with intravenous propofol. Anaesthesia was maintained with isoflurane in oxygen, and atipamezole (0.037 mg/kg) was given intramuscularly 10 mins after extubation. The UNESP-Botucatu multidimensional composite scale was used to conduct pain assessments before premedication and at 20, 60, 120, 240 and 360 mins post-extubation or until rescue analgesia was given. To compare groups, the 60 min postoperative pain scores and the highest postoperative pain scores were analysed via a two-tailed Mann–Whitney test, and the incidences of rescue analgesia were analysed via a Fisher’s exact test; P <0.05. Results There was no significant difference between groups for the 60 min ( P = 0.68) pain scores. The highest postoperative pain score was higher for GIMT compared with GOT ( P = 0.04). Only two cats required rescue analgesia, both from GIMT. The incidence of rescue analgesia was not significantly different between groups ( P = 0.46). Conclusions and relevance In the present study, preoperative administration of oral tramadol at 6 mg/kg to cats provided adequate analgesia for 6 h following ovariohysterectomy surgery.

A study of the attitudes of general surgical patients to the management of their postoperative pain showed that although 86% initially expressed satisfaction with their postoperative pain relief, a quarter of these did in fact have moderate, severe or unbearable, unalleviated pain. These, together with those who expressed dissatisfaction with their pain relief, constituted one third of the total number, indicating that a problem of postoperative analgesic management existed in the hospital. As a result, techniques of continuous intravenous infusion of narcotics and more frequent use of regional analgesia have been introduced.

Background: This prospective, randomised and blind study investigated the efficacy of laserpuncture for postoperative pain management in dogs. Method: Sixteen bitches were sedated with acepromazine and randomly treated before ovariohysterectomy with meloxicam 0.2 mg·kg−1 intramuscular or laserpuncture (wavelength 904 mm, frequency 124 Hz, potency 10 Joules, 100 s in each acupoint). Anaesthesia was performed with propofol, isoflurane/O2, and fentanyl. The Glasgow Composite Measure Pain Scale (GCMPS) and Dynamic Interactive Visual Analog Scale (DIVAS) were used to evaluate postoperative pain before and for 24 h after surgery. Morphine was administrated as rescue analgesia when pain scores were ≥3.33 (GCMPS). Differences between treatments, time points, and amount of rescue analgesia between groups were investigated by the Mann–Whitney test and the area under the curve (AUC) for GCMPS, Friedman, and Chi-squared tests, respectively (p < 0.05). Results: Dogs treated with laserpuncture presented lower GCMPS AUC for 24 h and lower GCMPS scores at 2 and 4 h postoperatively (p = 0.04). Three dogs treated with meloxicam required postoperatively rescue analgesia against none treated with laserpuncture. Conclusions: In this preliminary study, laserpuncture mitigated postoperative pain in dogs following ovariohysterectomy, and the technique is a promising adjunct to perioperative pain management in dogs undergoing soft tissue surgery.

Abstract Abstract 1933 Introduction: A pharmacokinetically derived schedule of flavopiridol administered as a 30 min intravenous bolus followed by 4-hour continuous intravenous infusion is active in fludarabine-refractory chronic lymphocytic leukemia, but no studies examining the feasibility and maximum tolerated dose of this schedule have been reported in relapsed multiple myeloma. Flavopiridol is a novel anti-cancer agent that targets cyclin dependent kinases (CDK) including the CDK9/cyclin T complex (preventing activation of RNA polymerase II), downregulates Mcl-1 and other anti-apoptotic proteins, and induces mitochondrial permeability changes. Flavopiridol is highly protein bound when in human serum, compared to protein binding seen in fetal bovine serum. This difference helps to explain the previous lack of clinical activity of flavopiridol (Dispenzieri et al, Haematologica, 2006) that targeted plasma concentrations based on in vitro cytotoxicity. A novel schedule of administration was designed to achieve and maintain target plasma levels predicted to be active in chronic lymphocytic leukemia from preclinical studies performed in human serum: 30-minute intravenous bolus (IVB) followed by 4-hour intravenous infusion (IVB/CIVI). This schedule, given for four of six weeks, is highly active in fludarabine refractory chronic lymphocytic leukemia. Methods: This was a phase I 3×3 single arm (standard method) study for relapsed myeloma patients having received at least two prior therapies. Adequate organ function was required with creatinine < 1.5 mg/dL and total bilirubin < 2x IULN. Adequate hematologic parameters were required with Hb > 9 g/dL, ANC>1500, and platelets > 50K during screening unless attributable to the patient's underlying myeloma. Results: 15 patients (ages 49–81 y.o.) with relapsed myeloma were consented. Median number of prior therapies was 7 (3-12). At the time of study entry, 8 patients displayed a complex karyotype, 2 patients with 17p deletion by CD138-selected FISH, and one patient with t(4;14); 3 patients with karyotypic chr 13 deletion and 9 patients by FISH. At study entry, 7 patients had ISS stage 3 disease, 4 with stage 2, and 4 with stage 1. 5 patients were treated in cohort 1 (30 mg/m2 bolus/30 mg/m2 CIV), 3 patients in cohort 2 (30 mg/m2 bolus/50 mg/m2 CIV), and 7 patients in cohort 3 (50 mg/m2 bolus/50 mg/m2 CIV). Median number of cycles received was 1. No patients achieved a confirmed PR – two patients achieved a minor response by IMWG criteria (see figure). The one patient with near 50% response in his IgA myeloma was the only patient with a t(4;14), 13-, and tetraploid cytogenetics by FISH. Grade 3/4 toxicities were significant with grade 4 neutropenia (10 patients), diarrhea (6 patients), transaminitis (4 patients), thrombocytopenia (3 patients), and anemia (5 patients). The most common toxicities included neutropenia, diarrhea, and AST elevation. Two patients in the first cohort and 1 patient in the final cohort were replaced due to inability to complete the first cycle. Pharmacokinetic results and immunohistochemical staining results for cyclin-D1 and pRb will be presented at the meeting; cyclin-D1 overexpression has been linked to CDK-inhibitor response (Dai Y et al, Cell Cycle 2006). One patient is undergoing screening to complete the final cohort and complete response and toxicity data will be reported. Discussion: Flavopiridol as a single agent given by intravenous bolus/continuous intravenous infusion causes significant neutropenia and diarrhea but objective clinical responses were uncommon.

Abstract Background: Unrelieved postoperative pain afflicts millions each year in low and middle income countries (LMIC). Despite substantial advances in the study of pain, this area remains neglected. Current systematic review was designed to ascertain the types of clinical trials conducted in LMIC on postoperative pain management modalities over the last decade. Methods: A comprehensive search was performed in June 2019 on PubMed, Cochrane Library, CINAHL Plus, and Web of Science databases to identify relevant trials on the management of postoperative pain in LMIC. Out of 1450 RCTs, 108 studies were reviewed for quality evidence using structured form of critical appraisal skill program. Total of 51 clinical trials were included after applying inclusion/exclusion criteria. Results: Results are charted according to the type of surgery. Eleven trials on laparoscopic cholecystectomy used multimodal analgesia including some form of regional analgesia. Different analgesic modalities were studied in 4 trials on thoracotomy, but none used multimodal approach. In 11 trials on laparotomy, multimodal analgesia was employed along with the studied modalities. In 2 trials on hysterectomy, preemptive pregabalin or gabapentin were used for reduction in rescue analgesia. In 13 trials on breast surgical procedures and 10 on orthopaedic surgery, multimodal analgesia was used with some form of regional analgesia. Conclusion: We found that over the past 10 years, clinical trials for postoperative pain modalities have evolved in LMIC according to the current postoperative pain management guidelines i.e. multi-modal approach with some form of regional analgesia. The current review shows that clinical trials were conducted using multimodal analgesia including but not limited to some form of regional analgesia for postoperative pain in LMIC however this research snapshot (of only three countries) may not exactly reflect the clinical practices in all 47 countries.
