A 28 yrs old female forty weeks gravida was scheduled for caesarean section for less fetal movement. She did not have any bad obstetric history and any complication during previous operation and anaesthetic procedure. Subarachnoid block was performed at L3-L4 interspace with 2.5ml (12.5mg)5% bupivacaine heavy. Suddenly the patient became cyanosed and she tried to tell something but could not talk. Then she was given 100% O2 by face mask but it was not fruitful. Then endotracheal intubation was attempted but failed to achieve due to increased jaw muscle tension and mouth could not be opened like masseter muscle spasm (MMS). At that stage patient became unresponsive and no pulse was palpable, blood pressure was not recordable. Intravenous adrenaline was given immediately and then 100mg of suxamethonium adminstered intravenously. The jaw relaxed within minutes and tracheal intubation was done. General Anaesthesia was maintained with O2/N2O, 0.4% halothane and atracurium. The reversal was good enough and the patient was haemodynamically stable. The patient transferred to the recovery room.

AbstractThe research aimed to examine ways in which applied tension for blood-injury phobia may be improved. The effect on blood pressure of two forms of muscle tension under three different rates of breathing is reported. Forty-five participants were randomly assigned to use either constant or rhythmic muscle tension under three different breathing rates (i.e., fast, slow, and normal). The effects on systolic and diastolic blood pressure were measured. Results indicated that both constant and rhythmic forms of muscle tension increased systolic and diastolic blood pressure. However, rhythmic tension was significantly more effective than constant tension at raising diastolic blood pressure. Breathing rate had no differential effects on blood pressure. Suggestions are made about modifications of Applied Tension in the treatment of blood-injury phobia.

Abstract. Introduction: To investigate the effects of a lutein complex supplementation on ocular blood flow in healthy subjects. Materials and Methods: Sixteen healthy female patients (mean age 36.8 ± 12.1 years) were enrolled in this randomized, placebo-controlled, double-blinded, two-period crossover study. Subjects received daily an oral dose of the lutein with synergistic phytochemicals complex (lutein (10 mg), ascorbic acid (500 mg), tocopherols (364 mg), carnosic acid (2.5 mg), zeaxanthin (2 mg), copper (2 mg), with synergistic effects in reducing pro-inflammatory mediators and cytokines when administered together in combination) and placebo during administration periods. Measurements were taken before and after three-week supplementation periods, with crossover visits separated by a three-week washout period. Data analysis included blood pressure, heart rate, intraocular pressure, visual acuity, contrast sensitivity detection, ocular perfusion pressure, confocal scanning laser Doppler imaging of retinal capillary blood flow, and Doppler imaging of the retrobulbar blood vessels. Results: Lutein complex supplementation produced a statistically significant increase in mean superior retinal capillary blood flow, measured in arbitrary units (60, p = 0.0466) and a decrease in the percentage of avascular area in the superior (−0.029, p = 0.0491) and inferior (−0.023, p = 0.0477) retina, as well as reduced systolic (−4.06, p = 0.0295) and diastolic (−3.69, p = 0.0441) blood pressure measured in mmHg from baseline. Data comparison between the two supplement groups revealed a significant decrease in systemic diastolic blood pressure (change from pre- to post-treatment with lutein supplement (mean (SE)): −3.69 (1.68); change from pre- to post-treatment with placebo: 0.31 (2.57); p = 0.0357) and a significant increase in the peak systolic velocity (measured in cm/sec) in the central retinal artery (change from pre- to post-treatment with lutein supplement: 0.36 (0.19); change from pre- to post-treatment with placebo: −0.33 (0.21); p = 0.0384) with lutein complex supplement; data analyses from the placebo group were all non-significant. Discussion: In healthy participants, oral administration of a lutein phytochemicals complex for three weeks produced increased ocular blood flow biomarkers within retinal vascular beds and reduced diastolic blood pressure compared to placebo.

The aim of the study was to determine the effectiveness of giving hydrotherapi foot soak in hypertensive patients. The study was conducted with one group pretestposttest design without a control group by measuring blood pressure (pretest) before being given an intervention in the form of foot soak hydrotherm against 15 people with hypertension in Banjar Sri Mandala, Dauhwaru Village, Jembrana Subregency. Then do the blood pressure measurement again (posttest) after finishing the intervention. After the study was completed, the results showed that before the hydrotherapi foot bath intervention, there were 0% of patients classified as normal, 13.32% in prehypertension category, 60.08% in hypertension category I and 26.60% in hypertension category II. After the intervention was given, there were 13.32% of the patients classified as normal, 66.68% in the prehypertension category, 20.00% in the first category of hypertension and no patients belonging to the second grade hypertension category. There is a decrease of 20-30 mmHg for systolic blood pressure and 0-10 mmHg for diastolic blood pressure after intervention. Based on the results of the study it can be concluded that the hydrotherapi foot bath is effectively used to reduce blood pressure in hypertensive patients in the Banjar Sri Mandala, Dauhwaru Village, Jembrana District.

ABSTRACT The reactivity of the hypothalamico-pituitary-adrenal axis was determined in 48 children, not suffering from any endocrine disorder. The free cortisol (F)- and corticosterone (B) content of plasma was determined in response to ACTH (clinical corticotrophin; A1 peptide), a corticotrophin releaser (lysine vasopressin) and a non specific stimulus (bacterial polysaccharide) as compared to saline. The two ACTH-preparations infused over one hour in a dose of 5 IU per child elicited a marked increase in both F and B. Lysine vasopressin in a dose of 0.5 IU per year of age similarly infused, exhibited a distinct linear increase in the two circulating cortical steroids, although the effect of this octapeptide was smaller than that of the two ACTH-preparations. Blood pressure was also measured during the infusion with vasopressin or saline. The systolic blood pressure was not significantly affected by vasopressin, but a significant rise in diastolic blood pressure was found. No correlation between the increase in diastolic blood pressure and in blood corticoids in response to vasopressin, was found. The intravenous administration of a relatively small amount of pyrifer caused a moderate increase in circulating F which was significant only at 4 and 6 hours after the injection of the pyrogen. The B content did not increase significantly above that of saline treated control children, presumably because of the relatively weak corticotrophic activity of the pyrogen under these conditions. A positive linear relation between body temperature and time was found. No correlation between increase in body temperature and increase in circulating F could be demonstrated.

Higher exercise blood pressure represents low cardiorespiratory status of an individual and vice versa. Thechanges in systolic and diastolic blood pressure in response to rhythmic isotonic muscular exercise in sedentaryyoung normotensive Nepalese students were assessed. Normal blood pressure in standing posture in maleand female subjects are about 115 / 75 mm of Hg. and 106 / 71 mm of Hg. respectively. Just after the exercisesystolic blood pressure increases moderately in both the sexes, whereas diastolic blood pressure remainsunchanged in most of the females. Diastolic blood pressure is found to be decreased slightly in the males,just after exercise. The present study indicates the cardiorespiratory status of the Napalese medical studentsis within normal range.

Background: Cardiovascular diseases are the leading cause of death in patients with chronic renal failure. When a patient undergoes dialysis, making AVF or AVG causes cardiovascular events. Understanding the relationship between complications: hypertension, heart failure, AVF or AVG (formation time, position, diameter) helps us monitor, detect, prevent and treatment of complications to limit the risk of death in patients with dialysis. Objective: Relationship between cardiovascular diseases and anatomosis of arteriovenous fistular in patients with regularly hemodialysis at Cho Ray Hospital. Methods: A cross-sectional study was conducted at Cho Ray Hospital from 2015 to 2016. The survey some cardiovascular diseases are done by clinical examination, tests for diagnostic imaging such as X-ray, electrocardiogram and echocardiogram: heart and diameter of anastomosis AVF, AVG. Results: The study population included 303 patients with chronic renal failure who were dialysis. Of which, patients aged 25-45 accounted for the highest proportion (43.9%). The proportion of male and female patients was similar (48.5% and 51.5% respectively). The mean value of systolic blood pressure on patients made AVF, AVG less than 12 months is higher than patients made AVF, AVG over 12 months, and there is negative correlation (r = -0.43) between AVF, AVG and systolic blood pressure (p <0.05). The mean value of diastolic blood pressure on patients made AVF, AVG less than 12 months is lower than patients made AVF, AVG over 12 months, and and there is positive correlation (r = -0.43) between AVF, AVG and diastolic blood pressure (p <0.05) (p <0.05). The prevalence of patients with heart failure made AVF, AVG over 12 months is higher than that of the under 12 months group, there is a negative correlation (r = - 0.43) between AVF, AVG diameter and EF index (p <0.05). Conclusion: It is important to note the diameter of anastomosis AVF, AVG in patients with chronic renal failure dialysis to limit cardiovascular complications, especially heart failure. Key words: Chronic kidney disease, hemodialysis.
