Objective: Aim of the study is to compare the efficacy of Ephedrine and Phenylephrine for treatment of hypotension afterspinal anaesthesia for elective caesarean section. Study design: Randomized Clinical Trial. Setting: Operation theatre Department ofAnaesthesiology, Combined Military Hospital Quetta. Duration of study: Six month from 16th Sep 2011 to 15th March 2012. Materialand Method: Seventy women undergoing LSCS for singleton pregnancy under spinal anesthesia were randomly assigned in group A andB (35 in each group). All patients preloaded with Lactated Ringer’s solution 15ml/kg body weight 10 minutes before administration ofspinal anaesthesia. Mean Arterial Pressure (MAP) was recorded before administration of spinal anaesthesia considered as Base-lineMAP and then at 1 Minute, 3 minutes & at 5 minutes after administration of spinal anaesthesia. When hypotension developed (MAP falls>20% from base line), intravenous single dose of ephedrine administered in group A patients, while in group B, Phenylephrine was given.Blood pressure was recorded after 1 minute following drug administration and up to 3 minutes at 1 minute interval. Patient handed over forprocedure after 10 minutes of spinal block. The SPSS version 13 was applied to the data. Mean and standard deviation were computed fornumerical variables like age, weight, height, systolic blood pressure, Diastolic blood pressure, and Mean Arterial pressure; whereasfrequency and percentages were employed to assess the categorical variable like efficacy. Chi-square test was used to compare theefficacy of intravenous bolus of ephedrine and phenylephrine. Statistical significance was taken at p<0.05. Results: There wassignificant difference in the efficacy of both the drugs, in the treatment of maternal hypotension. 74.29% were successfully treated ingroup “A” with a single dose of Ephedrine, as compared to group B where 51.43% were successfully treated with a single dose ofPhenylephrine. (p-value = 0.048). Conclusions: Intravenous ephedrine has more efficacy than phenylephrine in the treatment ofmaternal hypotension after spinal anesthesia for elective cesarean section.

Laryngoscopy and end tracheal intubation are stressful situation for the patients, as these procedures are capable of producing tachycardia, hypertension and arrhythmias. This study was conducted with the objective of arriving at an optimal dose of dexmedetomidine that can attenuate the hemodynamic response to laryngoscopy and intubation with minimal side effects. The current study was conducted in 60 patients, posted for elective surgery under general anesthesia withendotracheal intubation. The patients were divided into two groups: Group A and Group B. Group A received dexmedetomidine 0.5 μg/kg and group B received dexmedetomidine 1 μg/kg intravenously over 10 min prior to induction of anesthesia. The anesthesia technique was standardized in both the groups. Heart rate, systolic, diastolic and mean arterial pressure were monitored and recorded at 5min and 10 min of completion of infusion of study drug, after induction, and at 1 min, 2 min, 5 min after intubation. The baseline heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure were statistically similar in both the groups. After the infusion of the study drug the mean heart rate, mean systolic blood pressure, mean diastolic blood pressure, mean arterial pressure at all times were comparable in both the groups. Episodes of hypotension and bradycardia were also statistically similar in both the groups. Attenuation of hemodynamic response to laryngoscopy and intubation by dexmedetomidine is similar with the two doses: 0.5  μg/kg and 1 μg/kg. Both the doses of dexmedetomidine were devoid of any significant adverse effects.

Background: Postoperative nausea and vomiting (PONV) is a common complication associated with the use of anesthesia. Several antiemetics are used to reduce the incidence and severity of PONV. The aim of this study is to investigate the role of dexamethasone and ondansetron to treat PONV in patients undergoing cesarean section (c-section) under spinal anesthesia. Methods: This double-blind clinical trial study was performed on patients who were referred to the operating room of Haji Karim Asali Hospital of Khorramabad for elective cesarean section in 2016-17. Upon meeting the inclusion criteria, patients were allotted into two groups (n=60). Group A received 8mg of dexamethasone and group B received 4mg of ondansetron after spinal anesthesia. The Visual Analog Scale (VAS) questionnaire and Depression-Anxiety-Stress Scale (DASS) questionnaire was used for the analysis. Patients with mild to moderate stress, anxiety, and depression were included in the study. Data were analyzed using SPSS 16 software. Results: There was no difference in the demographic data of the two groups. The mean severity of nausea in group A was significantly higher than in group B. The frequency of vomiting in group A was 20 times higher than group B, which was found to be statistically significant, p = 0.018. Concerning the type of delivery with the frequency of nausea, the results showed that the frequency of nausea in group A was 3.24 times higher than group B, however, this difference was not statistically significant, p = 0.106. Conclusion: Based on the results of this study, ondansetron had a significant effect on the alleviation of postoperative nausea and vomiting, as compared to dexamethasone in c-section surgical candidates.

Background and Aims: Gabapentin and pregabalin, by decreasing noxious stimulus induced excitatory neurotransmitter release at central nervous system, may attenuate central sensitization and eventually decrease development of postoperative pain. We evaluated preemptive analgesic efficacy of single dose of oral gabapentin 600 mg and pregabalin 75mg for postoperative pain in patients undergoing lower limb orthopedic surgery under spinal anesthesia. Material and methods: A prospective, randomized, double blind study was conducted on 70 patients aged between 18 to 60 years with ASA grade 1 and 2 posted for lower limb surgeries under spinal anaesthesia. Patients were allocated into Group A and Group B receiving oral gabapentin(600mg) and oral pregabalin (75mg) respectively 1.5 hours before surgery. Primary objective was assessing duration and quality of analgesia by Visual Analogue Scale (VAS) score at 2,4,6,8,10,12,16,20 and 24 hours.Secondary objective was to assess total dose of rescue analgesic in first 24 hours, perioperative hemodynamic change and various side effects. Statistical Analysis used: Categorical data was compared using Chi- square test. Quantitative parametric data was analysed using unpaired student t-test. P value < 0.05 was considered statistically significant. Results: Mean duration of analgesia in Group A (10.53 ± 2.686 hours) was longer than Group B (7.943±3.199hr) (P = 0.0006).Mean number of analgesic dosesrequired in first 24 hourswere less in Group A (1.429 ± 0.5021) ascompared to Group B (1.771±0.6897) (P = 0.0202).All patients remained hemodynamically stable with no significant side effects noted in either group. Conclusion: We conclude that preemptive analgesic efficacy of oral gabapentin 600mg is better in comparison to oral pregabalin 75 mg for patients posted for lower limb orthopedic surgeries under spinal anesthesia.

Objective: To determine the efficacy of granisetron versus placebo (saline) for reducing shivering in patients undergoing lower segment caeserian section under spinal anaesthesia. Study Design: Comparative cross - sectional study. Place and Duration of Study: Department of Anaesthesia, Combined Military Hospital Rawalpindi, from Apr to Sep 2019. Methodology: Total 178 patients undergoing lower segment ceaserian section under spinal anaesthesia with age ranges from 18-40 years of American Society of Anaesthesiologists status I & II with full term pregnancy scheduled for elective caesarean section under spinal anaesthesia. Group A (n=92) received an intravenous bolus of 1 mg granisetron in a 10ml syringe and Group B (n=86) received intravenous bolus of normal saline in a 10ml syringe, drugs were administered immediately before spinal anaesthesia by anaesthetist as coded syringes. Heart rate, blood pressure, core body temperature and shivering scores were measured at 0 minutes, 30 minutes and 60 minutes, average surgery time recorded to be 60 minutes. Results: None of the patients in group A (drug group) exhibited appreciable post spinal shivering whereas 25 (29%) in group B (placebo) had clinically significant shivering necessitated administration of other established pharmacological agents to abort shivering in order to ensure patient comfort and satisfaction with statistically significant p-value of <0.05. Conclusion: Prophylactic injection granisetron was efficacious against post spinal shivering, moreover provides worth while relief of nausea and vomiting which is dilemma with most of the drugs employed for control of post spinal shivering.

Background Spinal anesthesia for surgical repair of hip fracture in the elderly is associated with a high incidence of hypotension. The synergism between intrathecal opioids and local anesthetics may make it possible to achieve reliable spinal anesthesia with minimal hypotension using a minidose of local anesthetic. Methods Twenty patients aged &gt; or = 70 yr undergoing surgical repair of hip fracture were randomized into two groups of 10 patients each. Group A received a spinal anesthetic of bupivacaine 4 mg plus fentanyl 20 microg, and group B received 10 mg bupivacaine. Hypotension was defined as a systolic pressure of &lt; 90 mmHg or a 25% decrease in mean arterial pressure from baseline. Hypotension was treated with intravenous ephedrine boluses 5-10 mg up to a maximum 50 mg, and thereafter by phenylephrine boluses of 100-200 microg. Results All patients had satisfactory anesthesia. One of 10 patients in group A required ephedrine, a single dose of 5 mg. Nine of 10 patients in group B required vasopressor support of blood pressure. Group B patients required an average of 35 mg ephedrine, and two patients required phenylephrine. The lowest recorded systolic, diastolic, and mean blood pressures as fractions of the baseline pressures were, respectively, 81%, 84%, and 85% versus 64%, 69%, and 64% for group A versus group B. Conclusions A "minidose" of 4 mg bupivacaine in combination with 20 microg fentanyl provides spinal anesthesia for surgical repair of hip fracture in the elderly. The minidose combination caused dramatically less hypotension than 10 mg bupivacaine and nearly eliminated the need for vasopressor support of blood pressure.

Object To investigate the clinical efficacy and safety of dexmedetomidine in flexible bronchoscopy under general anesthesia. Methods A total of 114 patients were randomly divided into intervention group A and control group B. Group A received dexmedetomidine, fentanyl, and propofol as anesthesia, while Group B received fentanyl and propofol only. Changes in heart rate, mean arterial pressure, pulse oxygen saturation, stress indices (blood cortisol, adrenaline, and norepinephrine levels), incidence of adverse events, anesthesia dose, duration of procedure, and recovery time were compared between the groups at specific time points T0, T1, and T2 during bronchoscopy. Results There was no statistical difference between the groups at T0. At T1 and T2, pulse oxygen saturation, mean arterial pressure, heart rate, and stress indices in group A were significantly more favorable than those in group B. The incidence of adverse events (5.26%) in group A was significantly lower than that in group B (17.54%), and patients in group A required less propofol and had a faster recovery time than patients in group B. Conclusion Dexmedetomidine use in flexible bronchoscopy under general anesthesia is safe and effective and decreases the stress response in synergy with propofol to provide hemodynamic stability.

Background: The common adverse effects of spinal anaesthesia include hypotension and bradycardia are due to sympathetic nerve blockade and activation of the Bezold-Jarisch reflex. The Bezold-Jarisch reflex in spinal anaesthesia may be mediated by peripheral 5-HT3 type serotonin receptors. We hypothesized that blockade of type 3 serotonin receptors by using intravenous Granisetron might reduce hypotension and bradycardia induced by spinal anaesthesia.Methodology: Sixty American Society of Anesthesiologists Physical Status I and II patients undergoing lower abdominal surgeries were randomized to receive either Normal Saline (control) or Granisetron 40 mcg/kg intravenously five minutes before subarachnoid block. Heart rates, systolic blood pressure, diastolic blood pressure, mean arterial pressure was recorded every two minutes for ten minutes and then every five minutes for another twenty minutes. Hemodynamic parameters were compared with baseline in each group.Results: There was decrease in all measured variables when compared with baseline values in both groups. There was less reduction in diastolic blood pressure in Granisetron group statistically significant at 10, 15, 20, 25 and 30 minutes. However, the less decrease in mean arterial pressure was statistically significant at 30 minutes only. There were no significant differences in systolic blood pressure and heart rate values between the groups.Conclusions: Granisetron given intravenously does not decrease the incidence of hypotension and bradycardia following subarachnoid block in patients undergoing lower abdominal surgery. However, it attenuates the fall of diastolic and mean arterial pressure spinal anaesthesia.Journal of Society of Anesthesiologists 2014 1(1): 36-39

Background: most of the lower segment caesarean sections are done under spinal anesthesia and in more that 80% of the cases, maternal fall in blood pressure can be observed intraoperatively. Throughout history many vasopressor drugs have been evaluated for the treatment. Aim: our research was conducted to compare the effect of phenylephrine with ephedrine given for the prophylaxis of prevention of intraoperative fall in blood pressure in females who are undergoing LSCS. Materials and Methods: a total of 100 cases were considered for our study and were randomly distributed in two groups. Group A cases were administered Phenylephrine while ephedrine was given to group B cases just after spinal anesthesia. Results: most of our study subjects were in the age group of 21-25 years who were in the range of 51-55 kgs. Spinal anesthesia was given by using bupivacaine & block level was checked at 2 & 5 mins. Phenylephrine was found to be superior in control of fall in blood pressure as more than 90% of the cases were brought back to their preoperative levels in less than 4 mins after spinal anesthesia. Whereas in group B, ephedrine took much more time of around 10 mins for control of BP. Conclusion: with proper monitoring of heart rate, phenylephrine is superior to ephedrine in controlling the fall in blood pressure. Keywords: Ephedrine, Phenylephrine, Hypotension, Bradycardia.

Introduction: Haemodynamic response to direct laryngoscopy and tracheal intubation has always been concern especially in cardiac patients. The use of fiberoptic bronchoscope for endotracheal tube placement may reduce the haemodynamic changes associated with intubation. Objectives: To compare haemodynamic changes (pulse and mean arterial pressure) following tracheal intubation, using direct laryngoscopic technique with fiberoptic bronchoscopic technique. Study Design: Randomized Controlled Trial (RCT). Settings and Duration: Department of Anaesthesiology, Intensive Care and Pain management Military hospital Rawalpindi. The study was of six months duration starting from April 2008 to October 2008. Subject and Methods: ASA-I and II patients (n=160) undergoing surgery meeting the inclusion and exclusion criteria.Informed consent was taken from all the patients undergoing the study. Patients were divided in two groups. Patients assigned to Group A got endotracheal intubation through direct laryngoscopic technique and Group B through fiberoptic bronchoscopic technique after induction of general anaesthesia. Pulse and Mean arterial pressure were recorded before induction of anaesthesia and three minutes after the intubation. Results: One hundred and sixty patients were studied. Eighty patients intubated through direct laryngoscopy (Group A) and eighty patients intubated through fiberoptic bronchoscope and it was observed that fiberoptic bronchoscopic intubation is haemodynamically safer as compared to conventional laryngoscopic intubation. Conclusion: The study concluded that bronchoscopic intubation provides better haemodynamic stability than direct laryngoscopic intubation.

Introduction/Objective. Despite frequent side effects such as hypotension, spinal anesthesia (SA) is still one of the best anesthetic methods for elective cesarean section (CS). Intermittent, oscillometric, non-invasive blood pressure monitoring (NIBP) frequently leads to the missed hypotensive episodes. Our goal was to compare continuous non-invasive arterial pressure (CNAP) monitoring with NIBP in the terms of efficiency to detect hypotension. Methods. In this study, we compared CNAP and NIBP monitoring for hypotension detection in 76 patients divided into two groups of 38 patients treated with ephedrine (E) or phenylephrine (P), during 3 min intervals, starting from SA, by the end of the surgery. Results. In group E, significantly lower mean systolic blood pressure (SBP) values with CNAP compared with NIBP (p = 0.008) was detected. CNAP detected 31 (81.6%) hypotensive patients in E group and significantly lower number 20 (52.6%) with NIBP (p = 0.001), while in P group CNAP detected 34 patients (89.5%) and NIBP, only 18 (47.3%), p = 0.001. CNAP detected significantly higher number of hypotensive intervals in E and P groups (p < 0.001). Umbilical vein pH was lower within hypotensive compared with normotensive patients in E and P groups, with CNAP and NIBP, respectively (p < 0.001, p = 0.027 in E, and p = 0.009, p < 0.001, in P group). Conclusion. CNAP is much more efficient in hypotension detection for CS during SA, which allows faster treatment of hypotension, thus improving fetal and maternal outcome.
