Abstract Background: Severe or uncontrolled post-operative pain may cause myocardial ischemia or infarction. Hence every anesthesiologist prefers long acting pain relief analogist drugs. Hence efficacies of different drugs were compared with their duration of sensory motor blockade with their side effects. Methods: 90 patients grouped into group A (45) and group B (45), Hyperbaric long and mg of Nalbupine in group B 10mg of Hyperbaric bupivaine with 3 mg of pentazocaine undergoing major abdomen pelvic surgery, their BP heart rate nerve blockage side was recorded. Results: VAS analogue was in grade was higher in group A, mean values of Diastolic systolic BP was significant (P<0.01) in group A, mean value of heart rate was more in group A mean value of hart rate was more in group B (P<0.01) duration of sensory and motor blockade was more in group B (P<0.01) and least side effects were observed in group B. Conclusion: Group B analgesics (penazocaine with hyperbaric bupivacaine) was much efficient, better relief for post-surgical pain. Key Words: Intrathecal, Analgesic, Nalbuphine, Hyperbaric Bupivacaine Pentazocaine, Telangana.
INTRODUCTION Uncontrolled post-operative pain may result in sympathetic activation and increase in myocardial oxygen consumption, which may lead to the development of myocardial ischemia and infarction by decreasing myocardial oxygen supply through coronary vasoconstriction(1) and attenuation of local metabolic coronary vasodilatation poorly controlled acute post-operative pain may be important predictive factor in the development(2) of chronic post surgical pain (CPSP). The relief of post-operative pain is a subject, which receiving increasing attention because effective pain control is essential for optimal care of surgical patients. Hence spinal anesthesia is a popular and commonly used worldwide, spinal anesthesia is advantageous in that it uses small dosage of anesthesthtic is simple to perform and offers a rapid onset of action, reliable surgical analgesia and good muscle relaxation. These advantages are sometimes offset by relatively short duration of action and complaint of pain when it wears off. The popularity of spinal block has well defined end points and anesthesiologist can produce the block relatively with a single injection.3 Hence to increase the duration spinal black two combination of analgesic drugs Nalbuphine with hyperbaric bupivacine were compared versus pentazocine with hyperbaric bapicaine in and their duration of sensory and motor blockage side effect were also noted to study the efficacy of these drugs. MATERIAL AND METHODS 90 patients aged between 20 to 60 years admitted in surgery and Gynecological ward of Mediciti institute of medical science hospital Ghanpur Medchal-501401 Telangana were selected for study. Inclusion criteria- Patients undergoing major abdominal and pelvic surgery Approved by physician regarding normalcy or fitness for surgery were included in the study. Methods- Two groups of 45 were selected by lottery method Group A- Received long hyper baric bupivacaine and mg of nulbupine Group B-Long of hyperbaric pupivacaine and 3 mg of pentazocaine all patients were explained the procedure and got their written consent complete haemogram, Urine examination, FBS, ECG, X-ray, Blood grouping. Blood urea, Serum creatinine was carried out pre-surgically. Visual Analogue scale- 10 cm line – grade-I 1-2 scale no pain 3-4 scale- grade-II, mild pain, 5-6 grade-III moderate pain, grade-IV 7-8 severe pain, 9-10 grade-V unbearable pain, patients were prepared overnight fasting oral alprazalam-0.5 mg and 150 mg ranitidine given at night before the day of sugary. Spinal anesthesia was performed under all aseptic precautions in the lateral position using 25-gauze quimcke needle at L3-4 or L4-5 interspaces. Following free flow of CSF respective drugs was injected into sub-arachnoids’ space and following parameters were recorded HR, RR,SPO2 and NIBP at certain intervals. Level of sensory blockage checked with 23 G Hypodermic needle immediately after SAB at mid-clavicular line and was measured every minute until it reached T8 dermatome level of motor blockage was assessed by using the Bromage scale 0=no motor block. Full flexion of knees and feet l= Inability to raise the extended leg, 2= Inability to flex knee but some flexion of feet possible. 3= unable to flex the ankle immediately after SAB and at certain intervals from laminates to 180 minutes. The duration of study about 4 years (2014 to 2018) Exclusion criteria – The patients having malignancy and immune compromised were excluded from the study. Statistical analysis- Vas analogue in both groups and side effects in both groups were classified with percentage comparison of group A and B – SBP, DBP, Heart rate, sensory and motor blockade was studied with 20077 SPSS software. The ratio of male and females were 2:1

DISCUSSION In the present study of comparative study of efficacy of Nalbuphine with hyperbric vaccine and pentazocine with hyperbaric Bupivacaine in Telangana Population. In the Visual analogue scale in group A 4(8.8%) were in grade I, 7(15.5%) in grade-2 11(24.4%) in grade-3, 23(51.1%) in grade-4. In group-B 2(4.4%) in grade-I, 9(20%) in grade-II, 20(44.4%) in grade-III, 14(31.1%) in grade-IV.(Table-1 A and B ) Comparison of systolic Blood pressure mean value of group was higher in group A than group B at certain interval of 10 minutes to 180 minutes (Table -2 and 3) In the comparison of heart rate certain interval in both groups mean value of group B was higher than group B (Table-4) In the comparison of duration of analgesic, sensory and motor block mean value of group A was higher than group B. but in sensory and motor black mean value of group B was higher than group A (Table-5) In the comparative study of side effects. The side effects were more higher in percentage in group A (Table-6) those findings were more or less in agreement with previous studies4,5,6.Bapivacaine is an amid amine anesthetic of high potency and long duration due to its high liposolubality. They develop enough intestinal pressure to cause diffusion of injected material in the dependent region but cause respiratory, nusea, vomiting and psycho mimetic reaction were also observed7. Pentazocine is the N-ally depravities of narcotic analgesic pentazocine is the strong analgesic with weak narcotic antagonist. It is advocated for the moderate to severe pain. Pentazocine has low abuse potential and is not controlled by narcotic regulation8. Hence it is much more safer than nalbuphine.As the adverse effects are concerned both groups treated with in tracheal opoids have minimal side effects, pruritis, respiratory depression, euphoria or dysphasia were not observed in the present study. Bradycardia was also reported in previous studies 9.Headache urine retention, nausea and vomiting were also reported in previous studies10. This double branded analgesic has provided prolonged post-operative analgesia with minimal and manageable side effects.
SUMMARY AND CONCLUSION The comparative study has proved that group B, pentazocine with Hyperbaric Bupivacaiene administered intrathecally (spinal) anesthesia was more efficient having prolonged, analgesic effect with minimal side effects post-surgically. But this study demands further pharmacological, patho-physilogical angiological, nutritional and genetic study because exact factors of analgesic which cause relief for certain duration is still un-clear.
