Background: Arterial hypotension following spinal anesthesia still remains the leading cause for maternal mortality and morbidity. Active management of hypotension and more so its prevention of its ads more safety value to spinal anesthesia, which is widely practiced worldwide. Preloading of patients with either crystalloid or colloid prevents the severity of hypotension. Objectives of the study was to compare the preloading efficacy of Ringers lactate solution (20 ml/kg) and 6% hydroxyl ethyl starch at 10 ml/kg in prevention of hypotension following spinal anesthesia in elective caesarean section.Methods: 100 ASA grade I and grade II subjects for elective caesarean section were studied in two groups. Group A (Ringer lactate group) 50 subjects and Group B (hydroxyl ethyl starch group) 50 subjects. Each group was preloaded over a period of 20 minutes before spinal anesthesia with either ringer lactate solution (Group A) at 20 ml/kg or 6% hydroxyl ethyl starch group at 10 ml/kg body weight. Main outcome measures were mean systolic blood pressure, mean diastolic blood pressure, mean arterial blood pressure and mean heart rate.Results: Demographic characteristics of both groups were comparable. Incidence of hypotension was significantly more in ringer lactate group. There was no significant difference of heart rate in both the groups. No allergic reaction was noted to hydroxyl ethyl starch. Vasopressor requirement was also low in hydroxyl ethyl starch group compared to ringer lactate group.Conclusions: Preloading subjects with 6% hydroxyl ethyl starch is beneficial than preloading with ringer lactate solution as it produces better hemodynamic stability to subjects.

Introduction: While most intravenous induction agents decrease arterial blood pressure, laryngoscopy and endotracheal intubation increase the heart rate and blood pressure. Propofol causes a decrease in systemic blood pressure whereas etomidate has minimal effects on the cardiovascular system. This study aims to evaluate and compare the hemodynamic effects of propofol and etomidate during induction and endotracheal intubation. Methods: 62 ASA I and II patients, 20-60 years of age, scheduled for elective surgery were enrolled in this prospective, randomised and double blind comparative study. Group A received inj. Propofol (2 mg/kg) and group B received inj. Etomidate (0.3 mg/kg), as induction agents. Heart rate, systolic blood pressure, diastolic blood pressure and mean arterial blood pressure were recorded after induction and after intubation at one, three, five and ten minutes and intergroup comparisons were made. Results: After induction the decrease in systolic, diastolic and the mean arterial pressures were more in group A compared to group B (p = 0.003, 0.004 and 0.002). After 1 minute of intubation all haemodynamic parameters increased from the baseline with no significant differences between the two groups (p >0.05). At three minutes the decrease in heart rate, diastolic blood pressure and mean arterial pressure was more in group A than group B with p values of 0.001, 0.002 and 0.05, however systolic blood pressures showed no significant difference (p = 0.144). The decrease in blood pressures showed significant difference between the two groups (p <0.05) at five and ten minutes but the decrease in heart rate remained significant only at five minutes of intubation (p = 0.001). Conclusions: Propofol and etomidate are both effective in preventing the haemodynamic changes due to induction and endotracheal intubation, with etomidate providing more haemodynamic stability.

Background: During caesarean section hypotension due to spinal block is secondary to the sympathetic blockade and aorto-caval compression by the uterus. It can have important consequences for the mother and may affect neonatal outcome. The present study was aimed to compare intravenous bolus doses of phenylephrine and ephedrine to treat maternal hypotension during spinal block for elective caesarean section.Methods: After fulfilling the inclusion criteria, 100 parturient were randomly allocated into two groups of fifty each. For spinal anesthesia lumber puncture was done and 12.5mg, 0.5% hyperbaric bupivacaine was given intra-thecally. In this observational study, patients who developed hypotension under spinal anesthesia were selected for the study. According to their group, patients received either ephedrine 6mg (Group E) or phenylephrine 75µg (Group P) as vasopressor. During the study, number of vasopressor boluses, hemodynamic response and time taken to recover from hypotension was noted.Results: Ephedrine and phenylephrine were used in the mean doses of 6.72±1.97mg and 91.5±31.38µg respectively. In 88% parturient single bolus dose of ephedrine was effective in treating hypotension while phenylephrine was effective in 78% parturient. There was no significant difference observed in total number of boluses used. No significant difference was seen in mean systolic blood pressure, mean diastolic blood pressure and mean arterial pressure over a given period of time in Group E and Group P. Mean systolic BP was less than 20% when compared to baseline in both the groups at different time intervals. In Group P the mean heart rate was significantly lower as compared to the Group E (p<0.05).Conclusions: Intravenous phenylephrine and ephedrine are both similar in performance in treating hypotension after spinal anesthesia for elective caesarean section and the hypotensive control offered is comparable.

This study aimed to assess whether low doses of albumin in the priming solution for cardiopulmonary bypass (CPB) reduce postoperative bleeding. Three-hundred and seventy-seven patients undergoing CPB were retrospectively assigned to group A (154 patients, CPB primed with 20 ml/kg Ringer Lactate solution + 0.75mg/kg albumin 20%) and group B (223 patients with 20 ml/kg Ringer Lactate). A significant difference was found in terms of reoperations for bleeding (group A 0/154 versus group B 9/223; P=0.033). The mean number of blood derivatives transfused per patient was higher in group B than in group A (p <0.001). Platelet count after CPB was higher in group A than in group B (175±52×103/μl versus 131±70×103/μl; P=0.045). The amount of postoperative bleeding was 525ml versus 680ml at 24hrs (p <0.001), 819ml versus 1102ml at 48hrs, (p <0.001), 963ml versus 1294ml at 72hrs, (p <0.045) (group A versus group B respectively). Crystalloid priming with low-dose albumin reduces postoperative bleeding.

Background: Hypertension is the most prevalent cardiovascular disease and the relevant data suggest that the burden, risk factors and co-morbidities associated with the essential hypertension is increasing with every passing day. It is one of the major chronic diseases resulting in high mortality and morbidity in today’s world. Aim: The aim of the study was to compare effects of cilnidipine and amlodipine on the blood pressure (BP), heart rate and proteinuria among patients of hypertension with chronic kidney disease.Methods: 100 patients were included in this study. Patients were randomly assigned into two groups Group A and Group B (50 each). Group A: Patients received Cilnidipine (5-10mg/day). Group B: Patients received amlodipine (5-10mg/day).Results: No significant difference in SBP, DBP, MBP and proteinuria while comparing both the groups of patients taking cilnidipine and amlodipine at baseline i.e. 0 to 12 week, 12 to 24 weeks and 0 to 24 weeks. Cilnidipine caused decrease in HR 0 to 12 week (p value 0.001), 12 to 24 weeks (p value 0.001) and 0 to 24 weeks (p value 0.0001). Amlodipine had increased heart rate from baseline to 12 weeks (p value 0.0001), 12 to 24 weeks (p value 0.051) and 0 to 24 weeks (p value 0.001). No significant difference was seen in any biochemical readings.Conclusions: There was a significant change in all the parameters including BP, heart rate, proteinuria and other biochemical tests when they compared within the group but no significant difference while comparing both the groups.

Background: Spinal anesthesia is a commonly employed technique for anesthesia for caesarean section and is associated with hypotension which may cause maternal morbidity. Prediction of hypotension before the procedure can reduce complications. The study aimed to evaluate the role of pulse plethysmograph in the prediction of hypotension in caesarean section patients under spinal anesthesia. Methods: The observational study was conducted on 50 patients who were undergoing emergency or elective caesarean section. Spinal anesthesia was performed by anaesthesiologist using a 25 or 26-gauge spinal needle with bupivacaine at L3-4 interspinous space. Pre and post-anesthesia observations such as the width of pulse plethysmograph, non-invasive blood pressure in another arm, and heart rate were recorded. Paired T-test, Wilcoxon sign rank test, and chi-square test was used to analyse data using R Studio V 1.2.5001 software. Results: Post spinal anesthesia minor fall in systolic blood pressure (SBP) was observed in 11 patients, moderate fall in 21 patients, severe fall in 8 patients and a massive fall in 10 patients. A significant difference was observed between mean pre- and post-spinal anesthesia SBP (P<0.001). Width of pulse plethysmograph (PPG) was maintained in 14 patients whereas, narrowed and significantly narrowed PPGs were observed in 29 and 7 patients, respectively. Significant association was observed between grades of SBP and width of PPG (P<0.05). Receiver operating characteristic curve showed the width of PGG was good for prediction of hypotension in patient (AUC=0.828). Conclusion: Width of PPG can be used to predict SA induced maternal hypotension.

Objective: Hesperidin (HES) is a flavonoid which is contained in citrus fruit peel. It has physiological effects on blood vessels such as strengthening capillary vessels. Thus, it is known to be one of the effective ingredients of herbal medicine. Some studies have shown that the intake of HES decreases blood pressure (BP) in spontaneously hypertensive rats. The antihypertensive effect of HES is suggested to be due to vasodilation by nitric oxide (NO). However, its mechanism has not been clarified in detail. In this study, we observed whether HES intake decreases BP in 2-kidney, 1-clip renovasucular hypertensive rats (2K1C) and evaluated endothelial NO synthase (eNOS) mRNA to investigate its role in the mechanism. Methods: Male Sprague-Dawley rats (6 weeks old) were treated with sham operation (SHAM) or clipping the left renal artery (2K1C). After surgery, the rats started receiving continuously a control diet (C) or a diet containing 0.1% (w/w) HES for 6 weeks. The systolic BP (SBP) was measured by a tail-cuff method every week. At the end of the protocol, mean arterial blood pressure (MAP) was measured in each rat under anesthesia. Then, the aortas were removed for extracting mRNA. eNOS mRNA expression was evaluated using real-time RT-PCR. Results: At the end of the protocol, SBP in 2K1C-C was significantly higher than in SHAM-C (170±6 vs 117±6 mmHg, p <0.001). On the other hand, 2K1C-HES was lower in SBP (141±4 mmHg) than 2K1C-C ( p <0.01). There were no significant differences between SHAM-HES (122±7 mmHg) and SHAM-C. MAP at the end of the protocol were similar to in SBP. ANOVA revealed mRNA expression of eNOS was significantly higher in 2K1C than in SHAM ( p <0.05), and showed no significant difference between C and HES, nor a significant interaction. Conclusion: Continuous intake of HES may suppress BP increase in 2K1C. The role of eNOS mRNA expression may not be involved in the mechanism.

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.

Cytroreductive surgery (CRS) and HIPEC are controversial effective treatment options for selected patients with peritoneal metastases. We retrospectively examined 4.500 patients with peritoneal metastases from different tumors from 2005 to 2020. Patients were divided in 4 groups, surgery plus HIPEC and then systemic chemotherapy: Group A n=730, Group B n=700, R0 surgery plus systemic chemotherapy, Group C n=870, palliative surgery plus systemic chemotherapy and Group D n=2.200, palliative care and best support. The postoperative outcomes, morbidity, mortality were compared between the 4 groups. The mean survival rates Group A=24,4+10,2m, Group B= 18,4+6,3m, Group C=12,3+5,7m, Group D=5,8+2,3m (p<0.05 between Gr A vr Gr B). There was no statistically significant difference in the 30-day mortality and morbidity. In conclusion CRS + HIPEC are feasible in 16% of our patients with peritoneal metastases and are associated with pro-longed survival.
