Background: Effect of pregabalin on heart rate and arterial pressure is important in its use as preemptive analgesia. Objective: The purpose of the present study was to evaluate the effect of pregabalin use as preemptive analgesia after abdominal hysterectomy on heart rate and arterial pressure.Methodology: This randomized double-blind placebo-controlled clinical trial was conducted in the Department of Anesthesia, Analgesia and Intensive Care Medicine, Banghabandhu Sheikh Mujib Medical University, Dhaka from July 2010 to June 2012 for a period of two years. Women aged between 40-60 years scheduled for abdominal hysterectomy under sub-arachnoid block were selected as study population for this study. A total of one hundred and twenty women meeting the above mentioned criteria were randomly allocated into two equal groups by card sampling. 120 cards, 60 for each group were prepared by another person who was not aware of the study. Group A was known as study group who were received 300mg oral pregnabin one hour before performance of SAB and group B was known as control group who were received matching placebo one hour before SAB. The patients were examined preoperatively and preoperative baseline parameters including heart rate, mean arterial pressure were recorded immediately before sub-arachnoid block (SAB). Patients were visited by the investigators at ½, 1, 2, 4, 12, and 24 h after operation. In each visit, heart rate and mean arterial pressure were measured and were recorded. Result: The present study was conducted on 120 women undergoing abdominal hysterectomy. Of them, 60 received preemptive single oral doses (300mg) Pregabalin (Group A) and the rest 60 received matching placebos (Group B) 1hr before surgery. The mean heart rate with SD before SAB was 79.4±4.7 and 90.5±5.7 in group A and B respectively (p=0.011). After 24 hours of operation the mean heart rate with SD was 73±5 and 85±4 in group A and B respectively (p= 0.043). The mean arterial pressure with SD before SAB was 94.3±5.3 and 95.8±20.4 in group A and B respectively (p=0.569). After 24 hours of operation the mean arterial pressure with SD was 89.4±4.45 and 96.1±2.56 in group A and B respectively (p <0.001). Conclusion: In conclusion the mean heart rate and arterial pressure are statistically significantly changes in the women after abdominal hysterectomy to whom pregabalin is used as preemptive analgesia.

Background Endotracheal intubation is an essential part of safe airway management but this stimulates the patient’s airway reflexes and predictably leads to haemodynamic derangement. Many drugs have been suggested in modifying in haemodynamic responses to laryngoscopy and intubation. Objectives To assess efficacy of three drugs - esmolol, fentanyl and lignocaine and to assess which one is more effective to attenuate haemodynamic response to direct laryngoscopy and endotracheal intubation. Methods A total number of 90 patients ASA class I and II were selected randomly as per inclusion and exclusion criteria in three groups, 30 patients in each group. Group A received esmolol 1.5mg/kg in the volume of 10ml (with distil water) 2min before intubation, group B received fentanyl 1.5mg/kg IV 5min before intubation and group C received lignocaine 1.5mg/kg IV 90 sec before intubation. Per-operative data were recorded at 1min, 2min, 5min and 10min after intubation. Results The mean heart rate, systolic, diastolic,mean arterial pressure before starting anaesthesia were similar in group-A (esmolol), B(fentanyl) and C(lignocaine). The mean values of heart rate and rate pressure product were significantly lower in group A(Esmolol) at 1 and 2 minute than group B(fentanyl) and at 1, 2 and 5 minute than group C(lignocaine). The mean values of systolic, diastolic and mean arterial pressure were slightly lower in group A(esmolol) at 5 minute than group B(fentanyl) and significantly lower at 1, 2 and 5 minute than group C(lignocaine). Conclusion Esmolol 1.5mg/kg is superior to lignocaine 1.5mg/kg for attenuation of haemodynamic response (HR, SBP, DBP, RPP and MAP) to laryngoscopy and endotracheal intubation and also superior to fentanyl for attenuation of HR and RPP.

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.

INTRODUCTION:Awake Fibreoptic Intubation is indicated in patients with anticipated diffcult airway, failed tracheal intubation, unstable cervical spine injury.Drugs used for conscious sediation includes Benzodiazepines, opioids, Propofol, either alone or in combination. All these drugs, though results in favourable intubating conditions, may also result in upper airway obstruction, hypoventilation, difcult airway instrumentation and oxygen desaturation. In order to address and overcome these issues, we compared the effects of parenteral dexmedetomidine and fentanyl on favourable conditions during awake breoptic bronchoscopic intubation. MATERIALS AND METHODS:A prospective,double blind,randomised study. 60 patients belonging to age group 25 to 60 years, ASA PS I & II posted for elective surgery under general anaesthesia with endotracheal intubation were randomly allocated into two groups, Group A(n=30) received injection dexmedetomidine, Group B(n=30) received injection fentanyl before awake breoptic bronchoscopic intubation. Hemodynamic parameters, cough score, postintubation tolerance score, ramsay sedation score were noted in both groups. The observed datas were analysed by SPSS version 21.0 software. RESULT: Demographic variable such as age,weight,ASA physical status were comparable in both the groups. The mean heart rate at 5mins,10mins after administration of study drug,intubation, 5mins postintubation are 76.73±5.51,73.63±5.99,76.37±8.11 and 75.03±7.94 respectively in Group A.The mean heart rate at 5mins,10mins after administration of study drug,intubation, 5mins postintubation are 78.57±5.04,76.93±5.11,103.30±4.21 and 99.37±4.02 respectively.The mean MAP at 5mins,10 mins after administration of study drug,intubation,5 mins post intubation are 86.80±2.33,85.77 ±2.56,87.83 ±5.73 and 87.30 ± 2.52mmHg respectively in Group A.The mean MAP at 5mins,10mins after administration of study drug,intubation,5 mins post intubation are 87.37±3.58,85.63 ±3.58,107.80 ±2.59 and 105.00 ±2.52 mmHg respectively. The post intubation SpO2 was 97.10 ±1.77 and 93.43± 1.17 % for Group A and Group B respectively.In Group A mean Ramsay sedation score is 2.87± 0.43 and in Group B the mean is 2.13 ±0.35. CONCLUSION:Dexmedetomidine group showed better hemodynamic stability and tolerance to awake endotracheal tube insertion through breoptic bronchoscope.Dexmedetomidine provides favourable intubating conditions during awake breoptic bronchoscope procedures with adequate sedation and without desaturation than fentanyl.

The relationship between graft blood flow, epicardial microflow and mean arterial pressure were studied to evaluate the use of repeated cardiopulmonary bypass (CPB) support for intraoperative heart failure following aorto-coronary bypass surgery. Ten patients with unstable angina and suffering from intraoperative heart failure (group A) were compared to 22 patients with stable angina (group B). In group A, during heart failure, the mean arterial pressure fell by 41 % (29.9 ± 6.8 mmHg, p < 0.01), graft flow (GF) by 67% (9.2 ± 2.6 ml/min, p < 0.01) and epicardial microflow by 64% (19 ± 4 AU, p < 0.01). After 15-56 min of assisted CPB support, the epicardial microflow and GF were partially restored. There were significant correlations between GF, epicardial microflow and CPB time. In group B, after protamine infusion, the epicardial microflow and GF were significantly greater than group A values (66 ± 14 AU, p < 0.001 and 29 ± 9 ml/min, p < 0.001, respectively). It is concluded that the use of temporary assisted CPB support to treat intraoperative heart failure allows the recovery of the myocardium and thereby restores the mean arterial pressure. The recovery of GF and epicardial flow occurred to a lesser extent. CPB support appeared to be suitable for about 60 min, probably because of increasing disturbance to the GF and the epicardial microcirculation.

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: Increased intraoperative bleeding during functional endoscopic sinus surgery (FESS) affects operative field visibility, which increases both duration of surgery and frequency of complications. Controlled hypotension is an anaesthetic technique in which there is deliberate reduction of systemic blood pressure during anaesthesia. The aim of the study was to compare the efficacy of dexmedetomidine against propofol infusion when used for controlled hypotension during FESS. Methods: A randomised, prospective, and single-blinded study was carried out, which included 80 patients of either sex of ASA grade І & ІІ who underwent elective FESS. Patients were randomly assigned to two groups: Group A (dexmedetomidine), Group B (propofol). Intraoperative mean arterial pressure (MAP), heart rate (HR), surgical grade of bleeding (based on the Fromme– Boezzart scale), and amount of bleeding were recorded. Results: Groups were well matched for their demographic data. There was a statistically significant difference (p < 0.05) between Group A and Group B in heart rate, mean arterial pressure (MAP) and mean total blood loss, with Group A being effectively in controlled on all three parameters during FESS. However, there was no significant difference (p > 0.05) in terms of surgical grade of bleeding between Group A and Group B. Conclusions: Both dexmedetomidine and propofol infusion are efficacious to facilitate controlled hypotension and haemodynamic stability intraoperatively.

Abstract Introduction Recent studies have indicated that obstructive sleep apnea syndrome (OSAS) is associated with hypertension. OSA is a common cause of sympathetic nervous activity. Increase of sympathetic nervous activity causes hypertension. Continuous positive airway pressure (CPAP) is the most useful treatment for OSAS. Good CPAP adherence treatment improve the risk of hypertension. This study examined the effect of intervention of medical staff on the adherence of CPAP, heart rate and sleep stages in patients with OSA. Methods All patients diagnosed with OSA and undergoing subsequent CPAP were clinically followed for 12 months to examine CPAP adherence, as well as longitudinal changes in blood pressure, average heartrate of 24 hours and sleep stages. They were divided into 2 groups, Group A: patients who had individual consulted in person by sleep physician and technicians before start using CPAP and Group B: patents who did not have individual consulted. Patients in both groups were consulted by sleep physician and technicians after start CPAP with utilizing tele-monitoring. If the adherence were poor, the patients were recommended to stop CPAP. We provided 3D accelerometer and an optical pulse photoplethysmography to all the patients and analyzed the data of heart rate and sleep stages. Results A total of 30 OSA patients underwent CPAP, were enrolled in the study and assessed for changes in mean heart rate and body weight during the study period. We found a significant reduction in mean heart rate in both group A and B compared with baseline (p&lt;-0.05). The patients aged under 50 years old and whose AHI&lt;20 times/hour have higher ratio of dropout CPAP therapy. There was no significant difference between Group A and Group B on the persistency rate of CPAP therapy. Also, no significant association was found between group A and B on the adherence of CPAP. Conclusion We showed the importance of the effect of intervention of medical staff on the adherence of CPAP and heart rate in patients with OSA the consultation after starting CPAP for a while with utilizing tele-monitoring data would be more effective compared with that in person before start using CPAP.

1. The systemic circulation at rest and during exercise was studied in ten normal male volunteers, after placebo on one occasion and after acute intravenous administration of the serotonergic antagonist ketanserin on another occasion. The effects of ketanserin on the components of the renin—angiotensin—aldosterone system, on plasma catecholamines and on exercise capacity for graded uninterrupted exercise were also investigated. 2. At rest in recumbency rapid intravenous injection of 10 mg of ketanserin, followed by a continuous infusion of 2 mg/h, produced an acute but transient fall in mean intra-arterial pressure of 6 mmHg compared with placebo. After 15 min the mean arterial pressure with ketanserin was within 2 mmHg of the mean pressure with placebo. In the sitting position both at rest and up to 30% of maximal work rate, the mean arterial pressure during ketanserin did not differ from the pressure on placebo. However, at higher levels of physical activity the rise in mean arterial pressure was lower with ketanserin; the pressure achieved with placebo was 7.5 mmHg higher at maximal work rate. Heart rate and cardiac output were significantly higher during ketanserin. 3. When the subjects were lying down and resting, plasma noradrenaline and adrenaline levels, plasma renin activity and angiotensin II concentration were not affected by ketanserin; however, these values were higher in the sitting position both at rest and during exercise. Plasma aldosterone was reduced by ketanserin during exercise and also when the subject was resting in the recumbent position. 4. Exercise capacity as measured by peak oxygen uptake was similar during ketanserin (3.09 ± se 0.12 litres/min) and during placebo (3.11 ± 0.13). 5. The data suggest that 5-hydroxytryptamine can have only a small role, if any, in pressure homoeostasis in sodium replete man at rest in recumbency. At moderate and heavy levels of exercise, the results are compatible with a role for 5-hydroxytryptamine in pressure regulation. Activation of the sympathetic nervous system by ketanserin is suggested by increases of plasma catecholamines, heart rate, cardiac output and plasma renin. The suppression of plasma aldosterone suggests that 5-hydroxytryptamine may have a role in the regulation of aldosterone secretion which is independent of angiotensin II.

Pneumoperitoneum is one of the most critical components of laparoscopic surgery, which has a negative effect on gas exchange and stress to circulatory buffering system. One of the top priorities of laparoscopic technologies is to minimize the impact on the respiratory and cardiovascular systems, metabolic dynamics and compensatory abilities of homeostasis. The main goal of this research work is to compare the effects of carboxyperitoneum and argonoperitoneum on the intraoperative dynamics of CO2 concentration as well as cardiovascular and respiratory characteristics in patients undergoing laparoscopic cholecystectomy for various forms of cholelithiasis. Materials and methods. Four experimental groups involved patients based on their nosological form of cholelithiasis and the gas used to induce pneumoperitoneum. All patients underwent laparoscopic cholecystectomy by means of standard procedure. Either medical carbon dioxide or medical argon was used to induce pneumoperitoneum. Intraoperative monitoring of blood carbon dioxide levels PaCO2 was performed by taking venous blood every 15 minutes. Capnometry was performed by means of mainstream analysis using “BIOMED” BM1000C modular patient monitor by recording the discrete values of PetCO2 every 15 minutes, as well as by analyzing photocopies of capnography curves every 15 minutes. Intraoperative echocardiography was performed to identify the mean arterial pressure (MAP), heart rate (HR) and cardiac output (CO) in order to assess the effects of different types of pneumoperitoneum on the cardiovascular system. Results. The obtained data confirm the expected difference in the indices of cardiorespiratory functions between patients with acute cholecystitis and cholelithiasis without signs of inflammation. The investigation revealed that under the influence of pneumoperitoneum, heart rate and mean arterial pressure increase, while the cardiac output decreases. The respiratory pressure marker depends more on the intra-abdominal pressure and presumably the patient’s body type than on the presence of inflammatory syndrome. Argon insufflation has a slight negative impact on the cardiovascular system. Particularly, the mean arterial pressure and heart rate increase, while the cardiac output marker is less decreased as compared to the use of carbon dioxide. Abdominal pressure has a significant effect on the cardiovascular and respiratory systems regardless of the used type of gas. The combination of high intra-abdominal pressure with the elevated head end of the operating table, which is a common practise during cholecystectomy, has especially great influence on cardiovascular and respiratory functions. Operation which is carried out at decreased pressure allows reducing the deviations of practically all indices. Conclusions. Thus, the cardiovascular and respiratory systems adapt under the influence of pneumoperitoneum, providing compensation for the negative effects of mechanical and resorptive-metabolic character. Compensatory-adaptive abilities of the cardiovascular and respiratory systems increase with the decrease of intra-abdominal pressure. The use of argon as a working gas for insufflation into the abdominal cavity during laparoscopy reduces the negative impact of pneumoperitoneum on the cardiovascular and respiratory systems, providing a greater reserve of homeostatic and buffer systems of the body.
