Atenolol prevents the formation of expansive hematoma after rhytidoplasty

Objective: To evaluate the perioperative use of atenolol in reducing the incidence of hematoma after rhytidoplasty.Methods: Between January 2007 and February 2013, 80 patients were randomized into two groups: Group A (n = 26) received perioperative atenolol in order to maintain heart rate (PR) around 60 per minute; Group B (n = 54) did not receive atenolol. Both groups underwent the same anesthetic and surgical technique. We monitored blood pressure (BP), HR, hematoma formation and the need for drainage. Patients were followed-up until the 90th postoperative day. The variables were compared between the groups using the ANOVA test. Continuous variables were presented as mean ± standard deviation and the differences were compared with the Student's t test. Values of p d" 0.05 were considered significant.Results: In group A the mean BP (110-70mmHg ± 7.07) and HR (64 / min ± 5) were lower (p d" 0.05) than in group B (135-90mmHg ± 10.6) and (76 / min ± 7.5), respectively. There were four cases of expansive hematoma in group B, all requiring reoperation for drainage, and none in group A (p d" 0,001).Conclusion: The perioperative use of atenolol caused a decrease in blood pressure and heart rate and decreased the incidence of expanding hematoma after rhytidectomy.

Abstract Introduction The use of 2 × 2000 mg myo-inositol +2 × 200 μg folic acid per day is a safe and promising tool in the effective improvement of symptoms and infertility for patients with polycystic ovary syndrome (PCOS). In addition, PCOS is one of the pathological factors involved in the failure of in vitro fertilization (IVF). Typically, PCOS patients suffer of poor quality oocytes. Patients and methods In an open, prospective, non-blinded, non-comparative observational study, 3602 infertile women used myo-inositol and folic acid between 2 and 3 months in a dosage of 2 × 2000 mg myo-inositol +2 × 200 μg folic acid per day. In a subgroup of 32 patients, hormonal values for testosterone, free testosterone and progesterone were analyzed before and after 12 weeks of treatment. The mean time of use was 10.2 weeks. In the second part of this trial it was investigated if the combination of myo-inositol + folic acid was able to improve the oocyte quality, the ratio between follicles and retrieved oocytes, the fertilization rate and the embryo quality in PCOS patients undergoing IVF treatments. Twenty-nine patients with PCOS, underwent IVF protocols for infertility treatment and were randomized prospectively into two groups. Group A (placebo) with 15 patients and group B (4000 mg myo-inositol +400 μg folic acid per day) with 14 patients were evaluated. The patients of group B used 2 months’ myo-inositol + folic acid before starting the IVF protocol. For statistically analyses Student’s t-test was performed. Results Seventy percent of the women had a restored ovulation, and 545 pregnancies were observed. This means a pregnancy rate of 15.1% of all the myo-inositol and folic acid users. In 19 cases a concomitant medication with clomiphene or dexamethasone was used. One twin pregnancy was documented. Testosterone levels changed from 96.6 ng/mL to 43.3 ng/mL and progesterone from 2.1 ng/mL to 12.3 ng/mL in the mean after 12 weeks of treatment (p < 0.05) Student’s t-test. No relevant side effects were present among the patients. The women in the IVF treatment the group A showed a higher number of retrieved oocytes than group B. Nevertheless, the ratio follicle/retrieved oocyte was clearly better in the myo-inositol group (= group B). Out of the 233 oocytes collected in the myo-inositol group, 136 where fertilized whereas only 128 out of 300 oocytes were fertilized in the placebo group. With regards to the oocytes quality, better data were obtained in the myo-inositol group. More metaphase II and I oocytes were retrieved in relation to the total number of oocytes, when compared with the placebo group. Also, more embryos of grade I quality were observed in the myo-inositol group than in the placebo group. The duration of stimulation was 9.7 days (±3.3) in the myo-inositol group and 11.2 (±1.8) days in the placebo group and the number of used follicle-stimulating hormone (FSH) units was lower in the myo-inositol group in comparison to the placebo group: 1850 FSH units (mean) versus 1850 units (mean). Discussion Myo-inositol has proven to be a new treatment option for patients with PCOS and infertility. The achieved pregnancy rates are at least in an equivalent or even superior range than those reported using metformin as an insulin sensitizer. No moderate to severe side effects were observed when myo-inositol was used at a dosage of 4000 mg per day. In addition, our evidence suggests that a myo-inositol therapy in women with PCOS results in better fertilization rates and a clear trend to a better embryo quality. As by the same way the number of retrieved oocytes was smaller in the myo-inositol group, the risk of a hyperstimulation syndrome in these patients can be reduced. Therefore, myo-inositol also represents an improvement in IVF protocols for patients with PCOS.

Abstract This prospective study assessed the effects of diaphragmatic breathing and systematic relaxation on depression, anxiety, and stress levels, as well as glycemic control, in patients with type 2 diabetes mellitus (T2DM). One hundred patients with T2DM were randomly assigned to two equal groups: Group A patients received conventional treatment for T2DM, and Group B patients received conventional treatment for T2DM plus training in diaphragmatic breathing and systematic relaxation and home practice of these stress-management techniques for 6 months. Stress, depression, and anxiety levels, blood sugar, and glycated hemoglobin (HbA1c) were recorded at baseline and after 6 months of treatment in all patients. Baseline characteristics were compared using the chi-square test and student’s t test. Changes in mental well-being and glycemic status were assessed for their significance in each group using student’s t test and compared between two groups using one-way analysis of covariance (ANCOVA). Baseline levels of the respective change outcome and duration of diabetes were used as covariates in the ANCOVA. A significant decrease was seen in depression, anxiety, and stress scores in Group B, but in Group A only the stress score decreased after 6 months. A significant decline occurred in blood sugar (fasting, 2-hour postprandial, and random) and HbA1c in both groups after 6 months. There was a larger decrease in depression and anxiety scores and HbA1c in Group B than in Group A. The decrease in HbA1c was significantly correlated with the decrease in anxiety and stress scores in both groups and with the depression score in Group A. Thus, the addition of diaphragmatic breathing and systematic relaxation to conventional T2DM treatment appears to have led to improvement in mental well-being and glycemic control in patients with T2DM.

Introduction: Acute coronary syndrome remains as one of the most important causes for morbidity and mortality in developed countries. Therefore, evidence-based management strategy is required to offset the loss of health during an acute coronary syndrome. An effective approach includes both medical and surgical methods. This study was conducted to evaluate the medical method of management. Objective: To study blood pressure and heart rate variability after administration of Ivabradine or metoprolol in cases with acute coronary syndrome. Materials and methods: The study was a Prospective single center observational study conducted in patients attending Cardiology Intensive Care Unit in Nayyar Heart and Superspecialty Hospital, a tertiary care centre located in an urban area. All patients with Acute coronary syndrome admitted to the emergency or cardiac care unit were analysed with ECG as a preliminary diagnostic test and confirmed with troponin markers. They were either given Ivabradine or Metoprolol. Baseline evaluation and follow up was done and necessary data was collected and analysed. Results: 100 patients were included in the study out of which 50 were given Metoprolol (Group A) and 50 were given Ivabradine (Group B). Themean age of studied cases was found to be 66.54 years in group A and 68.69 years in group B. It was observed that there was a fall in heart rate by 26.8 beats per minute with beta blocker and 24.4 beats per minute with Ivabradine. In case of blood pressure measurement, in patients with beta blocker administration, there was a fall of 25 mm Hg in systolic blood pressure and 17 mm Hg in diastolic blood pressure However, with Ivabradine there was only a fall of 8mm Hg in systolic Blood pressure and 6 mm Hg in diastolic blood pressure. Conclusion: Although Metoprolol is the drug of choice to decrease heart rate and blood pressure in acute coronary syndrome, Ivabradine is being increasingly used in cases where beta blockers are contraindicated as it has similar efficacy in lowering heart rate without compromising contractility of cardiac muscle, thereby maintaining LVEF and blood pressure. Keywords: Acute coronary syndrome, Beta Blockers, Metoprolol, Ivabradine.

Background: Abdominal hysterectomy is often a long duration procedure and warrants intense pain relief in the post-operative period. Dexmedetomidine when added to bupivacaine in subarachnoid block prolongs the duration of surgical anaesthesia, decreases blood loss and prolongs duration of post-operative pain relief. Aims and Objective: To compare two different doses dexmedetomidine as an adjuvant to bupivacaine in sub-arachnoid block in abdominal hysterectomy surgeries. Materials and Methods: 60 patients of age group 30-60 years posted for elective abdominal hysterectomies under American Society of Anaesthesiologists (ASA) physical classification I or II were randomly allocated into 2 groups of 30 each. Group A received 5 micrograms (μg) of dexmedetomidine along with 3.5 ml of 0.5% bupivacaine in sub-arachnoid block. Group B received 10 μg of dexmedetomidine along with 3.5 ml of 0.5% bupivacaine in sub-arachnoid block. Changes in blood pressure, heart rate, respiratory rate, oxygen saturation, ephedrine consumption, blood loss, duration of sensory block, duration of motor block, duration of analgesia were compared between two groups. Results: There was no significant difference in change in heart rate, respiratory rate, oxygen saturation, duration of sensory block, duration of motor block between two groups. Patients in group B had significant decrease in blood pressure, blood loss and significant increase in ephedrine consumption compared to Group A. The duration of analgesia was also prolonged in group B compared to Group A. Conclusion: Dexmedetomidine in dose of 10 μg is a better adjuvant to bupivacaine for abdominal hysterectomy surgeries.Asian Journal of Medical Sciences Vol.8(2) 2017 59-63

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.

Induction Agents

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: Ice massage is one of the common hydrotherapeutic procedures. The current study is first of its kind, conducted to evaluate the effect of ice massage to head and spine on blood pressure and heart rate variability in patients with hypertension. Materials and Methods: Fifteen hypertensive subjects with the mean ± standard deviation (SD) age of 48.87 ± 11.17 yrs were recruited and underwent only one session of ice massage to head and spine for 20 min. Blood pressure and heart rate variability were assessed before and immediately after the intervention. Results: Results of this study showed a significant reduction in systolic blood pressure (p = <.001), diastolic blood pressure (p < .001) and heart rate (p = .012), and a significant increase in R-R Interval (the intervals between adjacent R waves in the electro cardiogram) (p = .001) in the posttest assessments compared to its respective pre-test assessments. Conclusion: Results suggest that 20 min of ice massage to head and spine may reduce blood pressure and heart rate in patients with hypertension. However, there is no evidence that this provides any significant clinical impact for the patient.

Background: Laryngoscopy and tracheal Intubation are invariably associated with certain stress responses due to the sympatho-adrenal stimulation. These cardiovascular and neurohumoral alterations may directly affect the physiology and increase the risk. So far, various drugs have been tried but none has been considered ideal for blunting this presser response. We therefore, planned this comparative study to evaluate and compare the efficacy of intravenous magnesium sulphate (30 mg/kg) versus sublingual nitroglycerine spray (0.4 mg/spray) in attenuating the presser response to Laryngoscopy and Tracheal Intubation.Methods: Fifty patients, aged 15–50 years, scheduled for elective surgery under general anaesthesia, were randomly assigned to one of the two groups of 25 each, Group A (magnesium group) and Group B (nitroglycerine group). Study drug was given 90-120 seconds before tracheal intubation. Heart rate, Systolic blood pressure and Rate pressure product were recorded at different intervals after administering the study drug till 3 minutes after intubation.Results: Mean heart rate was significantly higher from the baseline at all times after administering the study drug in both the groups. Increase in systolic blood pressure as a presser response was limited to 7.25% in Group A and 5.83% in Group B from the baseline after tracheal intubation. There was relative hypotension after administration of the study drug in both the groups.Conclusions: Intravenous magnesium or sublingual nitroglycerine pre-treatment is found to be effective in attenuating the presser response to laryngoscopy and intubation. These drugs may lead to rise in HR but it is transient and dose dependent. However, both the drugs can significantly control the hypertensive response after laryngoscopy and intubation.
