Introduction: Patients who receive epidural opioids have fewer respiratory issues and can be deployed sooner in the postoperative phase than those who get standard, intermittent IV/IM dosing.The present study was done to compare the postoperative analgesia between tramadol and Buprenorphine through an epidural technique in patients undergoing lower abdominal surgeries, along with their onset, duration of analgesia, and side effects.
Materials and Methods: This study was a prospective comparative randomized studyOur study comprised 60 patients who came in for elective lower abdomen surgery and were randomly divided into two groups of 50 individuals each..Group T received 50 mg of Inj. Tramadol hydrochloride and Group B received 100 micrograms of Inj.Buprenorphine hydrochloride through epidural route (epidural catheterization done).Both groups of patients were monitored for 24 hours after surgery. In the postoperative phase, the VAS(VISUAL ANALOG SCORE) score for pain severity, onset and duration of analgesia, and side effects was monitored.
ResultsThe onset of analgesia in Group T was quicker, but the duration of analgesia was shorter than in Group B. Group T had a mean onset of analgesia of 9.65±4.25 minutes, whereas Group B had a mean onset of 14.85± 4.75 minutes. The mean duration of postoperative analgesia in Group T was 345.12±78.65minutes, while it was 595.45±88.42minutes in Group B, with a P-value of 0.02which was significant. Throughout the study, all of the patients were hemodynamically stable, and no severe side effects such as respiratory depression were detected. However, Group B had a higher incidence of nausea, vomiting, and pruritus than Group T.
Conclusion: At the end of the study, It was observed that epidural Buprenorphine gives a substantially longer and higher quality of analgesia than epidural TramadolNausea, vomiting, and pruritus were the most common adverse effects associated with injectable buprenorphine, which may be alleviated by antiemetics and antihistaminics, respectively.

Introduction:Postoperative analgesia after cesarean section poses unique clinical challenges
to anesthesiologist. Intrathecal buprenorphine is a promising drug for postoperative analgesia.
Aims: The aim of this study was to compare the efficacy of two doses of buprenorphine (45
μg and 60 μg) as an adjuvant to hyperbaric bupivacaine for postoperative analgesia in
caesarean section.
Materials and methods: This was a prospective, randomized, double-blind controlled study.
Ninety ASA physical status Class II parturients posted for elective caesarean section. The
computer-generated simple random sampling procedure was used to allocate the subjects into
three Groups A, B, C of 30 each.
Results: Addition of buprenorphine to intrathecal bupivacaine prolonged the duration and
quality of postoperative analgesia without producing any major side effect. The maximum
duration of analgesia and hence decreased analgesic requirement were obtained with 60 μg
buprenorphine. Addition of buprenorphine did not have any adverse outcome on the baby as
assessed by Apgar score.
Conclusion:Addition of buprenorphine to hyperbaric bupivacaine provides postoperative
analgesia after cesarean section without significant maternal and neonatal side effects.

Bupivacaine hydrochloride is 2-piperidenecarboxamide-1-butyl-N-(2, 6 dimethyl phenyl) monochloride, a monohydrate is a white crystalline powder that is freely soluble in 95% ethanol, soluble in water, and slightly soluble in chloroform or acetone. Local anesthetics mainly work on the cell membrane of the axon. The considerable transient rise in sodium ion permeability that's also required for impulse transmission is inhibited. Depolarization in response to the stimulus is thereby blocked, and the resting membrane potential is preserved. A pre-anesthetic check-up was done one day before the surgery. Patients were evaluated for any systemic diseases and laboratory investigations were recorded. The procedure of SAB was explained to the patients and written consent was obtained. The preparation of patients included a period of overnight fasting. Hemodynamics during the operative period was similar in the 30 mcg group and 60 mcg, but for the 90 mcg group incidence of hypotension and respiratory depression was observed for a few cases.

Spinal anesthesia can be performed with a wide range of local anesthetic drugs. using local anesthetics alone is associated with a relatively short duration of action.1 Postoperative pain control is a major problem with spinal anesthesia using local anesthetics alone, and thus early analgesic intervention is needed in the postoperative period. Bupivacaine is the local anesthetic most commonly used, although lidocaine, tetracaine, procaine, ropivacaine, levobupivacaine, and prilocaine may also be used. After institutional ethical committee approval, 90 patients aged between 18-60 years undergoing lower abdominal and lower limb surgeries were selected. A detailed history, complete physical examination, and investigations were done for all patients. Informed consent was taken. The study population was divided into 3 groups with 30 patients in each group. The study has demonstrated that increasing the dose of buprenorphine with 0.5% bupivacaine in spinal anesthesia significantly decreases the time of onset of sensory and motor block and prolongs the duration of sensory, motor blockade. The requirement of postoperative rescue analgesia is also decreased as the dose increased.
