Impact of butorphanol versus sufentanil on postoperative cognition and inflammation in elderly: a pilot study.

This randomized controlled trial aimed to compare the effects of butorphanol and sufentanil on early post-operative cognitive dysfunction (POCD) and systemic inflammation in older surgical patients. Patients (aged 65 years or above) undergoing surgeries with general anesthesia were randomized to either the butorphanol group (40 μg/kg during anesthesia induction) or the sufentanil group (0.4 μg/kg). Cognitive function changes during the perioperative period were assessed using the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) scale up to 3 days after surgery. POCD was defined as a Z-score or composite Z-score greater than 1.96 for both MMSE and MoCA scores. Circulating inflammatory factors, including tumor necrosis factor-alpha (TNF-α), interleukin 1 beta (IL-1β), and interleukin 10 (IL-10), were measured using enzyme-linked immunosorbent assay. The study included 114 patients (median age: 71 years, 57.7% male). Compared to sufentanil, butorphanol significantly reduced the incidence of POCD on the first (11.5% versus 32.7%, p = 0.017) and third day (3.8% versus 15.4%, p = 0.046) after surgery. Additionally, patients receiving butorphanol had significantly lower circulating levels of TNF-α and IL-1β at the time of discharge from the post-anesthesia care unit and on the first and third day after surgery (p < 0.05 for all comparisons). Furthermore, circulating IL-10 levels were significantly higher in patients receiving butorphanol (p < 0.05 for all comparisons). Administration of butorphanol during anesthesia induction, as opposed to sufentanil, was associated with a significant reduction in the early incidence of POCD in older surgical patients, possibly attributed to its impact on systemic inflammation.Clinical trial registration: The present study was registered in the China Clinical Trial Center (ChiCTR2300070805, 24/04/2023).

Comparative Analgesic Efficacy of Intramuscular Dexamethasone, Ketorolac, Tramadol, and Butorphanol with Regard to Postoperative Pain After Mandibular Third Molar Surgery

ABSTRACT Surgical removal of the third molar often resulted in postoperative pain which affected the quality of life of the patients. Pharmacological management of pain includes NSAIDS or steroids. The present study compared four drugs, viz. Group 1 (4 mg dexamethasone injection); Group 2 (30 mg ketorolac); Group 3 (50 mg tramadol injection); and Group 4 (1 mg butorphanol injection) in the management of postoperative pain after third molar surgery. We observed that in comparison with the first and third postoperative pain between groups, it revealed the lowest mean pain score in the butorphanol group, followed by dexamethasone and tramadol group and the highest mean score in the ketorol group (P value &lt;0.0001). We conclude that butorphanol with low dosage can be effectively used for reducing postoperative discomfort after surgery.

Safety and Efficacy of Butorphanol as an Analgesic for Patients on Mechanical Ventilation after Cardiac Surgery: An Exploratory Prospective Observational Study

Purpose: This study assessed the safety and analgesic efficacy of butorphanol in patients receiving mechanical ventilation after cardiac surgery. Methods: This was a prospective study. A consecutive cohort of patients from our medical center who underwent cardiac surgery followed by mechanical ventilation between January 2021 and April 2022 were divided into two groups and received either butorphanol or morphine for analgesia, and all patients also received propofol for sedation. Statistical analysis was performed using the t-test or chi-square test, and the pain levels of the two groups were compared based on the Critical-Care Pain Observation Tool (CPOT), as well as sedation based on the Richmond Agitation-Sedation Scale (RASS), and incidences of adverse events. Results: The two groups, each of which contained 70 patients, reported similar analgesic efficacy; the CPOT score was almost 0 and the RASS score was between 0 and –3. The butorphanol group experienced significantly lower rates of nausea, respiratory depression, and drowsiness. However, the two groups experienced similar rates of vomiting, pruritus, drowsiness, constipation, and delirium, durations of mechanical ventilation, use of sedative drugs, and lengths of stay in the intensive care unit. Conclusions: For patients on mechanical ventilation after cardiac surgery, butorphanol can provide analgesic effects similar to those of morphine with a potentially lower risk of certain adverse events.

Application of Butorphanol versus Sufentanil in Multimode Analgesia via Patient Controlled Intravenous Analgesia After Hepatobiliary Surgery: A Retrospective Cohort Study.

We investigate the efficacy and safety of butorphanol in multimodal analgesia combined with dexmedetomidine and ketorolac via patient-controlled intravenous analgesia (PCIA) after hepatobiliary surgery, as compared with sufentanil. Postoperative follow-up data of hepatobiliary surgery patients in Henan Provincial People's Hospital from March 2018 to June 2021 were collected retrospectively and divided into butorphanol group (group B) or sufentanil group (group S) according to the postoperative intravenous controlled analgesia scheme. The baseline characteristics and surgical information of the two groups were matched through propensity score matching (PSM). A total of 3437 patients were screened, and PSM yielded 1816 patients after matching, including 908 in the butorphanol group and 908 in the sufentanil group. Compared with group S, the incidence of moderate-to-severe pain on the first postoperative day and the second postoperative day was lower in group B during rest (3.2% vs 10.9%, P<0.001; 1.2% vs 4.6%, P<0.001), and during movement (7.0% vs 18.9%, P<0.001; 2.6% vs 8.7%, P<0.001). Patients receiving butorphanol had a lower morphine consumption (50mg vs 120mg, P<0.001). The bolus attempts of an analgesic pump in group B were significantly lower than in group S (1 vs 2, P<0.001). Postoperative hospital length of stay was shortened in group B (11d vs 12d, P=0.017). The occurrence of postoperative vomiting was lower in group B (1.4% vs 3.0%, P=0.025) than in group S. However, more patients in group B experienced dizziness (0.9% vs 0.1%, P=0.019). Compared with sufentanil, the application of butorphanol in multimodal analgesia combined with dexmedetomidine and ketorolac via PCIA ameliorated postoperative pain after hepatobiliary surgery, with reduced opioid consumption and shorter postoperative hospital length of stay.

Effect of butorphanol-soaked nasal packing after endoscopic nasal surgery: a double-blind, randomized, placebo-controlled trial

ObjectiveThis study was designed to investigate the effect of butorphanol-soaked nasal packing on analgesia and sleep quality in patients undergoing bilateral endoscopic nasal surgery. MethodsSixty-six patients were enrolled and randomly allocated into three groups: group B1 (butorphanol 0.03mg/kg), group B2 (butorphanol 0.04mg/kg) and group N (control group). The primary outcome was postoperative pain scores evaluated by a Visual Analogue Scale (VAS) at 2h (T1), 8h (T2), 24h (T3) and 48h (T4) after surgery. Secondary outcome was postoperative sleep quality measured using Subjective Sleep Quality Value (SSQV). ResultsPostoperative VAS scores of butorphanol groups were significantly lower than the control group at T2, T3 and T4. VAS scores at each time point did not differ between groups B1 and B2. On the first and second nights after surgery, SSQV was higher in butorphanol groups than in the control group. There were no significant differences in SSQV1 and SSQV2 between group B1 and group B2. The incidence of respiratory depression, dizziness, agitation and rescue analgesic use did not show difference among three groups. ConclusionsButorphanol-soaked nasal packing can reduce pain and improve sleep quality after bilateral endoscopic nasal surgery without increasing adverse effects. A concentration of 0.03mg/kg may be appropriate for clinical application. Level of EvidenceLevel 1B.

Effect of anesthesia induction with butorphanol on postoperative nausea and vomiting: A randomized controlled trial

BACKGROUND Postoperative nausea and vomiting (PONV) are common complications that affect the recovery and well-being of elderly patients undergoing gastrointestinal laparoscopic surgery. AIM To investigate the effect of butorphanol on PONV in this patient population. METHODS A total of 110 elderly patients (≥ 65 years old) who underwent gastrointestinal laparoscopic surgery were randomly assigned to receive butorphanol (40 μg/kg) or sufentanil (0.3 μg/kg) during anesthesia induction in a 1:1 ratio. The measured outcomes included the incidence of PONV at 48 h after surgery, intraoperative dose of propofol and remifentanil, Bruggrmann Comfort Scale score in the postanesthesia care unit (PACU), number of compressions for postoperative patient-controlled intravenous analgesia (PCIA), and time to first flatulence after surgery. RESULTS The results revealed a noteworthy reduction in the occurrence of PONV at 24 h after surgery in the butorphanol group, when compared to the sufentanil group (T1: 23.64% vs 5.45%, T2: 43.64% vs 20.00%, P &lt; 0.05). However, no significant variations were observed between the two groups, in terms of the clinical characteristics, such as the PONV or motion sickness history, intraoperative and postoperative 48-h total infusion volume and hemodynamic parameters, intraoperative dose of propofol and remifentanil, number of postoperative PCIA compressions, time until the first occurrence of postoperative flatulence, and incidence of PONV at 48 h post-surgery (all, P &gt; 0.05). Furthermore, patients in the butorphanol group were more comfortable, when compared to patients in the sufentanil group in the PACU. CONCLUSION The present study revealed that butorphanol can be an efficacious substitute for sufentanil during anesthesia induction to diminish PONV within 24 h following gastrointestinal laparoscopic surgery in the elderly, simultaneously improving patient comfort in the PACU.

Comparison of two sedation protocols for long electroretinography in horses using the Koijman electrode

BackgroundIn modern times, horses are utilized not only for labour and transportation purposes but also for recreational activities such as competition and pleasure riding. In these various pursuits, the role of vision plays a crucial role. Electroretinography is the most used test to diagnose diseases of the retinal outer segment. There is a wide variety of devices to perform the electroretinography differing one from each other in the corneal electrode and the light stimulation. The Koijman electrode has been tested in dogs but not in horses. The main purpose of this study was to compare electroretinography parameters from horses sedated with detomidine alone or in combination with butorphanol, during a standardized protocol using the Koijman electrode and RETI-port® system. Seven mares were allocated to the detomidine and detomidine plus butorphanol group in a randomised, controlled, crossover study. Friedman and Willcoxon-signed ranked tests were used to compare the electroretinogram parameters. A Student’s t-test was used to compare differences in the number of artefacts to valid values ratio obtained under both sedation protocols.ResultsDark adaptation peaked after 16 min under scotopic conditions in both groups. No significant differences in electroretinogram parameters between groups were observed. During the mixed rod and cone response evaluation under scotopic conditions, all mares made a movement of the head resulting in a high number of artefacts. The detomidine plus butorphanol group showed a non-significant tendency to have fewer artefacts and a longer duration of sedation compared to the detomidine group.ConclusionsDetomidine alone or combined with butorphanol may be suitable to use Koijman electrode and the RETI-port® to perform a standardized long protocol in horses with some adaptations.

A comparative study between butorphanol and tramadol as adjuvant with epidural bupivacaine for post-operative analgesia after pelvi-acetabular surgery

Epidural analgesia using local anaesthetic agent is popular simple, effective &amp; economical way of providing postoperative analgesia. In few previous study opioids were added with local anaesthetics, so that even small doses can provide profound analgesia of longer duration with less side effects. We compared the efficacy of epidural butophanol with tramadol as adjuvant with bupivacaine, for postoperative analgesia in view of safety profile among opioids. Sixty patients undergoing pelvi-acetabular surgery were randomly assigned into two groups B &amp; T in double blinded fashion. Group B received 2ml Butorphanol (2mg) &amp; group T received 2ml of tramadol(100mg) as adjuvant with 8ml Bupivacaine (0.125%) as first does. 1ml Butorphanol (1mg) in group B &amp; 1 ml Tramadol(50mg) in group T as adjuvant with 9ml Bupivacaine (0.125%) as subsequent does when VAS&amp;#62;4. Quality of analgesia assessed using VAS for 24hours. Duration of analgesia calculated by time of first analgesia request. Post-operative nausea vomiting &amp; sedation compared. Both butorphanol group &amp; tramadol group provide adequate analgesia but significantly lesser requirement of analgesic doses was observed in the group T compared to Group B. Duration of analgesia in Group B was about 6-7 hour &amp; in Group T was about 8-9 hours. More PONV in Group T &amp; more sedation in group B seen. Therefore, it suggests that epidural bupivacaine with butorphanol has better quality of analgesia in comparison with bupivacaine with tramadol. Although bupivacaine with tramadol has longer duration of analgesia but causes significant nausea &amp; vomiting.

In present study there was no statistically signica RESULTS: nt difference in both in both group with respect to demographically such as age, gender, height, weight and ASA grade. In this study it was found that VAS score increased at 5 hours in butorphanol group whereas in tramadol group increased at 6 hours and there was statistically signicant difference in VAS score from 4 hours to 8 hours postoperatively. There was no statistically signicant difference seen between two groups in mean reductions of heart rate. In this study there was no statistically signicant difference between two groups in mean systolic and mean diastolic blood pressure from baseline till 120 mins. The mean time of onset of sensory block in the study was 12.79±1.43 min in Group A and 13.87±1.43 min in Group – B. It can be CONCLUSION: concluded from this study that epidural bupivacaine with butorphanol provides a rapid but shorter duration of analgesia when compared to epidural bupivacaine with tramadol. Epidural bupivacaine with butorphanol had lesser side effects like nausea, vomiting, pruritus than bupivacaine with tramadol group.

A Comparative Study of Epidural Butorphanol and Fentanyl as Adjuvants with 0.5% Bupivacaine for Postoperative analgesia in Lower Abdominal Surgeries

The pain is considered as sixth vital sign. Achieving adequate peri-operative and post -operative analgesia is of paramount importance to the anesthesiologist. This can be done by multiple approaches. One such technique is use of Epidural opioids. This study evaluates the analgesic efficacy of epidural fentanyl and butorphanol in lower abdominal surgeries for post -operative analgesia. Aims: To compare the degree of post-operative analgesia using butorphanol and fentanyl administered by epidural route. Settings and Design: Study setting: Tertiary care Hospital Study Design: A Prospective Double Blinded Randomised Clinical Study Methods and Material: A total of 60 Patients posted for elective lower abdominal surgeries were randomly selected for the study. The patients aged 20-60 years of ASA grade one and two posted for elective lower abdominal surgery were selected for the study. Drugs used were explained to the patients and also educated about Verbal numerical scale for assessment of pain. Patients were divided into two groups: Group A: receives Butorphanol 1mg mixed with 15 ml Bupivacaine 0.5%diluted upto 20 ml. Group B: receives Fentanyl 100 microgram mixed with 15 ml Bupivacaine 0.5% diluted upto 20 ml. Statistical analysis used: Statistical data was analysed using • Chi-square test • Student t-test (Paired and unpaired t-test) • A P value of &lt; 0.05 is significant and &gt;0.05 is not significant Results: The demographic variables were comparable in both groups. Both inj. Butorphanol 1 mg and Inj. Fentanyl 100 mcg given epidurally with Inj. Bupivacaine 0.5% as a single shot provided excellent operative conditions and satisfactory post-operative analgesia in both the groups. However, the duration of post-operative analgesia was much longer in the butorphanol group than Fentanyl group and was statistically significant. No serious side effects were noted in both groups. The method is economical, safe, convenient and acceptable and also poly pharmacy is avoided. Conclusions: Both fentanyl and butorphanol are safe and effective as epidural agents for postoperative analgesia with little side effects.

Pre-operative administration of butorphanol mitigates emergence agitation in patients undergoing functional endoscopic sinus surgery: A randomized controlled clinical trial.

This study explored the effectiveness of pre-operative intravenous injection of butorphanol in the alleviation of emergence agitation (EA) in patients undergoing functional endoscopic sinus surgery (FESS). Patients (n = 708) were randomized into two groups. The butorphanol group (Group B, n = 358) received butorphanol infusion (20 ug/kg) before anesthesia induction, while the control group (Group C, n = 350) received an equal volume of normal saline infusion. General anesthesia was induced with sufentanil, propofol, and rocuronium, and was maintained with sevoflurane and remifentanil. Vasoactive drugs maintained the hemodynamic indices within 20% of the baseline. The incidence of EA was significantly lower in Group B than that in Group C (Group B vs. C: 24.3% vs. 31.4%, respectively; P = 0.034). The times to spontaneous breathing (26.5 min vs. 23.7 min, P = 0.011), verbal response (36.0 min vs. 33.4 min, P = 0.012), and extubation (31.0 min vs. 28.7 min, P = 0.025) were longer in Group B, and the grade of cough (0.33 vs. 0.43, P = 0.024) at extubation in Group B was lower than that in Group C (P = 0.024). The mean arterial pressure at the end of the operation (P = 0.004) and at 5 min after extubation (P = 0.008) was higher and hypotension was less prominent (0.6% vs. 2.6%, P = 0.030) in Group B. Pre-operative intravenous injection of butorphanol decreased the incidence of EA after FESS and provided smooth and hemodynamically stable emergence without extending the stay in post-anesthesia care unit. https://www.clinicaltrials.gov/, identifier NCT03398759.

A Comparative Study of Epidural Butorphanol and Epidural Fentanyl for Postoperative pain relief in Lower Limb Orthopaedic Surgeries.

Background: Epidural narcotic agonists like fentanyl, and morphine has been studied as an adjunct to Bupivacaine for intraoperative and to provide epidural postoperative analgesia. Side effects like pruritus, nausea, vomiting, respiratory depression, and urinary retention occur with their use. The search for an effective analgesic with no or low incidence of side effects is continuing. Aims and objective: To evaluate the onset of anaesthesia, duration of analgesia with epidural administration of Butorphanol and fentanyl in 2 groups. Observe and compare side effects between these groups during post-operative period. Material and Methods: We had done this study on 60 patients with Orthopaedic fractures (lowerlimb), which are treated with IM IL nailing femur and tibia distributed to two groups of 30 each. Surgery was done under CSE technique, with Group A receiving butorphanol and Group B Fentanyl as adjuvant. The onset, duration of analgesia and side effects were recorded in each group. Results: The onset of analgesia was rapid in Fentanyl group (3.26+/- 0.95) than Butorphanol group (6.54 +/-1.10). Duration of analgesia was longer in Butorphanol group (330 +/- 62 minutes) in comparison to Fentanyl group (210 +/- 32 minutes). Quality of analgesia is better in Butorphanol group (80%) than Fentanyl group (43 %). Side effects were more in Group B than Group A. Conclusion: Epidural Fentanyl has faster onset of analgesia. Epidural Butorphanol has longer duration of analgesia with better quality of analgesia. Epidural butorphanol has fewer side effects when compared to Fentanyl.

Analgesic effect of butorphanol tartrate combined with hydromorphone on patients with cesarean section: A prospective cohort study

To evaluate the analgesic effect of butorphanol tartrate combined with hydromorphone on the patients with cesarean section, we conducted a prospective cohort study. A total of 90 patients were given patient-controlled intravenous analgesia (PCIA) with hydromorphone for 24 hours after the cesarean section. After stopping PCIA, they were divided into 2 groups randomly. The cases treated with butorphanol tartrate intravenous drip were evaluated as the butorphanol group (n = 45) and the cases treated with saline were evaluated as the control group (n = 45). We compared the vital signs, analgesic effect, adverse reactions, the bladder and gastrointestinal function recovery, and neonatal jaundice between the 2 groups. The visual analog score in butorphanol group was significantly lower than that of control group at 3 and 4 hours after stopping PCIA (P < .05), but there was no significant difference in visual analog score at 6 and 12 hours after stopping PCIA. The first time of getting out of bed and urination in butorphanol group was significantly later than that in control group while there was no significant difference in the first anal ventilation and the neonatal jaundice index between the 2 groups. We should pay attention to the pain of patients with cesarean section after stopping PCIA. The combination of butorphanol tartrate and hydromorphone play a good effect to relieve the pain while nursing care should be strengthened to urge patients to take early activities to reduce the occurrence of urinary retention.

Intravenous butorphanol as an adjunct to patient-controlled epidural analgesia with ropivacaine and sufentanil in labor: a randomized controlled study

Background: Butorphanol was safely used for obstetric analgesia for many years. We attempted to determine if it increases the analgesic effect during patient-controlled epidural labor analgesia (PCEA) and if it affects the labor-process. Methods: Term pregnant women (N = 60) were randomly assigned to two groups, to receive either 1 mg intravenously butorphanol or 10 mL normal saline as placebo at 10 min before intrathecal anesthesia. Pain score, duration of first and second stage of labor, mode of delivery, umbilical artery blood gas, Apgar scores and adverse effects were recorded. Result: Butorphanol shortened the duration of the second stage of labor (t = –2.41, p = 0.019). Women in butorphanol group showed significantly increased incidence of pruritus (x2 = 20.32, p = 0.000), but they also showed significantly increased incidence of the adverse events such as maternal somnolence and dizziness (x2 = 8.366, p = 0.004; x2 = 26.447, p = 0.000 respectively). The pain scores of the two groups showed a linear reduction within 1 h (F = 8.878, p = 0.004), and from intravenous injection of butorphanol to the 5th minute after intrathecal analgesia, the analgesic scores of butorphanol group were significantly lower than those of placebo group (p &lt; 0.05). At the third hour after intrathecal injection, the Visual analogue scale (VAS) score was significantly lower in butorphanol group than placebo group (95% Confidence Interval (CI) –3.02 to –0.28; t = –2.51, p = 0.021). Conclusions: i.v. butorphanol 1 mg alleviates the labor pain during intrathecal puncture, and It will be easier to get the cooperation of pregnant women and shortens the second stage of labor. It effectively relieved the pruritus, but increased the incidence of dizziness and somnolence.

Comparative Study of the Effect of Clonidine and Butorphanol as Adjuvant to Intrathecal Bupivacaine for Post Operative Analgesia in Lower Abdominal and Lower Limb Surgeries

Background: Intrathecal adjuvants to local anesthetic enhance the quality and duration of spinal anaesthesia. The present study was aimed to comparatively evaluate clonidine and butorphanol as adjuvants to intrathecal hyperbaric bupivacaine for subarachnoid blockade during lower abdominal and lower limb surgeries. Patients and Method: Sixty adult consented patients, undergoing elective lower-abdominal and lower-limb surgeries under subarachnoid blockade, were inducted in a blind randomized prospective study conducted in the Department of Anesthesia, GMC Jammu and allocated into 2 equal groups to receive either 3.2 ml of 0.5% hyperbaric bupivacaine (16mg) with 0.2 ml of Clonidine 30 µgm (Group I) or with 0.2 ml of Butorphanol 200 µgm (Group II). Patients were compared for the onset and duration of sensory and motor blockade, intraoperative hemodynamic changes, time to first rescue analgesia, etc. Result: The mean onset time of sensory block was 3.18±0.56 min in Group I and 3.69±0.83 min in Group II. Complete motor block was achieved in 11.53±3.05 min in Group I and in 12.72±3.17 min in Group II, with no significant difference. (p = 0.138) The duration of motor block was 294.28±33.85 min in Group I, as compared to patients of butorphanol group 245.71±30.92 min,(p = 0.046). The need for rescue analgesia was significantly earlier in Group II, ie at 211.09±20.74 min, while at 256.32±24.40 min in group I. Conclusion: Clonidine and butorphanol are good adjuvants to hyperbaric bupivacaine for spinal anaesthesia. Clonidine provides longer duration of sensory and motor blockade and prolonged duration of postoperative analgesia compared to butorphanol.

Evaluation of Ketamine Hydrochloride in Combination with Midazolam, Dexmedetomidine and Butorphanol as Balanced Anaesthesia in Cats

Background: As cats undergo stress at the time of presentation before surgery and therefore sedation is required often. It is very difficult to choose a balanced anaesthetic protocol during the surgical intervention in the case of a cat. Therefore, the present study was undertaken to evaluate the effect of ketamine hydrochloride in combination with midazolam, dexmedetomidine and butorphanol as balanced anaesthesia on clinico-physiological, haematological, serum biochemical profile in the surgical management of cats undergoing neutering. Methods: The study was performed on 18 clinical cases of cats which were brought to the Teaching Veterinary Clinical Complex, College of Veterinary Sciences and Animal Husbandry (CVSc and AH), Central Agricultural University (CAU), Selesih, Aizawl, Mizoram for elective surgery such as neutering. Cats were randomly divided into 3 equal groups, i.e. Gr. A, Gr. B and Gr. C. Animals were premedicated with glycopyrrolate @ 0.01 mg/kg, i/m. After 10 minutes of premedication, in Gr. A ketamine hydrochloride @15 mg/kg and midazolam @ 0.5 mg/kg, in Gr. B ketamine hydrochloride @10 mg/ kg and dexmedetomidine@ 5 mcg /kg and in Gr. C ketamine hydrochloride @ 5 mg/kg, dexmedetomidine@ 5 mcg/kg and butorphanol @ 0.2 mg/kg was administered intramuscularly. Clinico-physiological and haemato-biochemical profiles were evaluated at 0 minute (baseline), then at 15, 30 and 60 minutes after administration of anaesthetic agents to evaluate their anaesthetic effect. Result: In the case of time for induction, the quality of induction, assessment of peri-operative analgesia, depth of anaesthesia and quality of recovery there was no significant difference among all three groups. In Gr. B, animals showed significantly higher duration of recumbency (DOE) and recovery. The assessment of peri-operative analgesic effect among the groups revealed that analgesia during the perioperative period appeared best in Gr. C protocol. In regards to depth of anaesthesia, ketamine hydrochloride in combination with dexmedetomidine and butorphanol group showed a better result. Rectal temperature decreased significantly (P greater than 0.05) up to 60th minutes in Gr. A, but it remained within the physiological range. Heart rate raised significantly (p less than 0.05) from the baseline (0 minutes) onwards and decreased significantly (p less than 0.05) till the end (60 minutes) of the study in Gr. C. The respiration rate was significantly (p less than 0.01) different in between time intervals for all three groups. No significant difference was observed on haemato-biochemical observation except glucose level which significantly increased after induction of anaesthesia. In conclusion, treatment with ketamine hydrochloride in combination with dexmedetomidine and butorphanol led to acceptable sedation and mild changes in clinico-physiological, haematological, serum biochemical profile in comparison to the other two groups.

Comparison between Tramadol and Butorphanol for Treating Postoperative Catheter-Related Bladder Discomfort: A Randomized Controlled Trial.

Background Intraoperative catheterization often leads to postoperative catheter-related bladder discomfort (CRBD) during the restoration period. This study aimed to assess the curative effect of butorphanol as a K receptor agonist in the treatment of postoperative CRBD. Patients and Approaches. Sixty patients with CRBD who underwent elective nonurological surgery at the postanesthesia care unit were randomly and evenly assigned to two groups. The control group was slowly injected with tramadol 1.5 mg/kg using a Murphy dropper, whereas the experimental group was intravenously injected with butorphanol 0.02 mg/kg. Severity, pain score, and sedation score of CRBD were evaluated at 0 min, 5 min, 15 min, 30 min, 1 h, and 6 h later. Results The severity score of CRBD and visual analog scale pain score were lower in the butorphanol group than in the control group, whereas the sedation score was higher in the butorphanol group than in the control group. Conclusion Butorphanol relieves on postoperative urination discomfort and pain compared with tramadol.

Evaluation of the performance of two new generation pulse oximeters in cats at different probe positions and under the influence of vasoconstriction.

ObjectivesThe aim of this study was to compare the failure rate of two new generation pulse oximeters at different probe positions, and with and without vasoconstriction, in anaesthetised cats.MethodsThis prospective clinical study included 103 cats in which the new generation pulse oximeters, the Rad-5 (Masimo) and EDAN H100N (EDAN), were evaluated. Premedication consisted of the vasoconstrictive drug combination butorphanol (0.2 mg/kg IV) and dexmedetomidine (5 µg/kg IV), or butorphanol only (0.2 mg/kg IV). Pulse oximeter failure rate at the tongue was compared between both groups. Pulse oximeter failure rate was also analysed at the alternative probe positions of the lip, pinna, knee fold and toe in the butorphanol group. Student’s t-test, Wilcoxon matched pairs signed rank test, Mann−Whitney U-test, Friedman test and χ2 test were performed. A P value <0.05 was considered to be statistically significant.ResultsOverall failure to achieve an adequate signal was 37.6% with the Masimo and 48.0% with the EDAN pulse oximeter (P <0.0001). At the standard probe position on the tongue, the Masimo failed in 4.5%, while the EDAN failed in 35.3% (P <0.0001). Vasoactive premedication increased the failure rate for the Masimo from 3.8% to 5.2% (P = 0.3414) and for the EDAN from 22.4% to 49.0% (P <0.0001). At the alternative probe positions of the lip and knee fold, failure rates for the Masimo were lower (39.7% and 81.4%) than with the EDAN (52.6% and 94.4%; P = 0.0231 and P = 0.0005, respectively), while the Masimo failed more often at the pinna (63.5%) than the EDAN (47.4%; P = 0.0044). At the alternative probe position of the toe, the failure rate for the Masimo (32.7%) was not different from the EDAN (38.5%; P = 0.7547).Conclusions and relevanceThe Masimo pulse oximeter had lower signal failure rates at the standard probe position on the tongue and at 2/4 alternative probe positions. The standard probe position on the tongue had the lowest failure rate for both devices. Dexmedetomidine-induced vasoconstriction increased the failure rate for the EDAN but not for the Masimo pulse oximeter.

Intra Venous Butorphanol versus Intravenous Nalbuphine for (Intra Operative) Balanced Anaesthesia and Post Operative Analgesic Effect in Patients Undergoing Laparoscopic Surgery

Laparoscopic surgery has replaced many of the open surgeries because of its advantages. Both the groups of drugs have hemodynamic stability, analgesia, sedation and decrease the requirement of other anesthetic drugs. So we have chosen Butorphanol and Nalbuphine to study the analgesia and hemodynamic changes in both groups. In our study mean heart rate was lower in Butorphanol group compare to Nalbuphine group. Similarly fifty patients of ASA I&amp;II scheduled for elective laparoscopic surgery, were randomized in to butorphanol group and nalbuphine group. It was observed that there was significant rise in systolic blood pressure &amp; Diastolic Blood pressure after intubation in fentanyl group compare to Butorphanol. This study finds that suppression of sympathetic response to laryngoscopy and intubation was better with Butorphanol than Fentanyl. This study analysis indicates that both Butorphanol and Nalbuphine help in maintaining a steady haemodynamic state all throughout the procedure.

Efficacy and Safety of Butorphanol Use in Patient-Controlled Analgesia: A Meta-Analysis

Objective This meta-analysis evaluates the efficacy and safety regarding usage of butorphanol in patient-controlled analgesia (PCA). Methods Several databases such as PubMed, Cochrane Library, Embase, CNKI, and VIP were explored with the help of computer search and manual retrieval. Randomized controlled trial (RCT) was selected, and the meta-analysis was conducted using RevMan 5.1. The primary efficacy endpoint was the postoperative visual analog scale score, postoperative Ramsay sedation scale (RSS), and adverse events. Results Nine RCTs met the inclusion criteria and were included in this meta-analysis. No significant differences were found between the butorphanol group and nonbutorphanol group at 12 h and 48 h. The postoperative RSS score at 12 h, 24 h, and 48 h was representative of the calming effect of butorphanol. No significant difference was found on the endpoint of the postoperative RSS score at 12 h, 48 h, and 24 h. The RSS score was lower in the butorphanol group in comparison to the nonbutorphanol group. The butorphanol group was also associated with lower rate of nausea, vomiting, itching, and dizziness compared to the nonbutorphanol group. Conclusion Butorphanol may be used in PCA as a successful postoperative analgesia and is also associated with lower side effects. Further research is needed to verify the efficacy and safety of butorphanol.
