The Comparative Study

 Introduction: Growing incidence of hypertension and its significant association with diabetes mellitus are being observed in both developing and developed countries around globe. Scanty literature is available about the comparative study of inter-arm variation of blood pressure in normal individuals and diabetic among Nepalese population. This research was performed to determine extent of inter-arm variation in normal individuals and diabetics. Methods: A descriptive observational study was carried out from 2013 January to 2014 January in a tertiary level teaching hospital of Nepal. After taking the consent and giving necessary instructions, blood pressures were measured in both the arms one after another in sitting posture using mercurial sphygmomanometer and Littman cardiosonic stethoscope. Arterial blood pressure was measured by palpatory method followed by auscultatory method The cuff pressure at which the tap sound were first perceived was noted as systolic blood pressure (SBP). Similarly, diastolic blood pressure (DBP) was noted at the point where the sound disappeared. Results: A total of 120 volunteers between ages of 40-80 years were studied. Highly significant inter-arm variation of both SBP and DBP was found in diabetics as compared to normal (p<0.01). Highly significant inter-arm variation was found in diabetic male and female as compared to their normal counter parts (p<0.01). Conclusion: This study showed that there was significant inter-arm variation of SBP and DBP in diabetic and normal individual. So, this study encourages to measure blood pressure (BP) in both arms for proper treatment planning of an individuals.

Precise Relationship

In neonatal intensive care units where direct arterial blood pressures obtained via a transducer are unavailable, a fluid-filled spinal manometer has been used. The latter method is practical and convenient although its validity has not been confirmed. This study is designed to establish the precise relationship between the blood pressure obtained by the manometric method and by direct recording via the arterial transducer. Materials and Methods Eleven infants with umbilical artery catheters in place 1 to 2 cm above the diaphragm were selected for the study. In all instances, the arterial catheters were placed for clinical management of various illnesses.

Abstract This study describes a non-invasive medical device capable of measuring arterial blood pressure (BP) with a combination of inflationary and deflationary procedures. The device uses the pressure cuff pressure signal, arterial skin-surface acoustics, and photoplethysmography (PPG) to make a sensor-fusion estimation of blood pressure readings. We developed an apparatus composed of 1) a modified off-the-shelf oscillometric blood pressure system, 2) a contact microphone with an amplifier, 3) and high-sensitivity pulse oximeter, and its control electronics.

A modification of the auscultatory blood pressure method, the phonoarteriogram, was developed. The innovated method essentially is a modified amplifying stethoscope. The pressure in the cuff is recorded from a pressure transducer, and the systolic and diastolic criteria are recorded from a microphone. The phonoarteriogram gives the advantages of a permanent record, includes pulse rate and pulse sound data, is not affected by hearing acuity, permits determinations often denied using auscultation in high ambient noise and exercise conditions, and eliminates observer bias. Three hundred and forty resting determinations and 218 exercise determinations on 60 subjects indicated good agreement between the phonoarteriogram and auscultation. In 50 systolic and diastolic intra-arterial determinations before compression of the cuff, during rest and exercise from one subject, the phonoarteriogram was as valid as auscultation. In 56 intra-arterial determinations during deflation of the cuff, i.e., simultaneous with the indirect measurements, during rest and exercise from a second subject, the phonoarteriogram was less fallible than auscultation, particularly during exercise.

Ischemic Encephalopathy

Dysfunctional cerebrovascular autoregulation may contribute to neurologic injury in neonatal hypoxic-ischemic encephalopathy (HIE). Identifying the optimal mean arterial blood pressure (MAPopt) that best supports autoregulation could help identify hemodynamic goals that support neurologic recovery. In neonates who received therapeutic hypothermia for HIE, we hypothesized that the wavelet hemoglobin volume index (wHVx) would identify MAPopt and that blood pressures closer to MAPopt would be associated with less brain injury on MRI. We also tested a correlation-derived hemoglobin volume index (HVx) and single- and multi-window data processing methodology. Autoregulation was monitored in consecutive 3-h periods using near infrared spectroscopy in an observational study. The neonates had a mean MAP of 54 mmHg (standard deviation: 9) during hypothermia. Greater blood pressure above the MAPopt from single-window wHVx was associated with less injury in the paracentral gyri (p = 0.044; n = 63), basal ganglia (p = 0.015), thalamus (p = 0.013), and brainstem (p = 0.041) after adjustments for sex, vasopressor use, seizures, arterial carbon dioxide level, and a perinatal insult score. Blood pressure exceeding MAPopt from the multi-window, correlation HVx was associated with less injury in the brainstem (p = 0.021) but not in other brain regions. We conclude that applying wavelet methodology to short autoregulation monitoring periods may improve the identification of MAPopt values that are associated with brain injury. Having blood pressure above MAPopt with an upper MAP of ~50–60 mmHg may reduce the risk of brain injury during therapeutic hypothermia. Though a cause-and-effect relationship cannot be inferred, the data support the need for randomized studies of autoregulation and brain injury in neonates with HIE.

Background: Dynamic exercises are known to elicit hemodynamic changes such as an increase in arterial blood pressure and heart rate. Zumba and ZOCA are part of a fast growing group of dance fitness programmes designed to provide a cardiovascular dynamic workout. Despite their growing popularity, very few studies have been done to provide knowledge regarding the hemodynamic changes associated with these exercises. Methods: Case study in which 27 females took part in either a Zumba or ZOCA class. Using digital blood pressure monitors, recordings of blood pressure and heart rate were taken, firstly, before commencement of the exercise, secondly, after 30 minutes after exercise and thirdly, at the end of the class.Results: Mean baseline blood pressures were 118 (SD = 14) mmHg and 77 (SD = 7) mmHg, systolic and diastolic blood pressures, respectively. After 30 minutes of dancing, mean systolic blood pressure increased to 130 (SD = 19) mmHg (p˂ 0.05) while diastolic blood pressureonly rose to an average of 80 (SD = 8) mmHg (p˃ 0.05). At the end of the class (after the cool down phase) mean systolic blood pressure reduced to 109 (SD = 13) mmHg (p˂0.05) while diastolic blood pressure reduced to 74(SD = 12) mmHg (p˂ 0.05). Conclusions: Zumba and ZOCA elicited significant hemodynamic changes that can be attributed to these exercises stimulating the cardiovascular regulatory mechanisms (e.g central command and exercise-pressor) sufficiently and hence resulting in autonomic adjustmentsthat were concurrent with effective dynamic exercise.

And Control

External aortic compression is an emergency manoeuvre proposed to reduce postpartum haemorrhage and permit time for resuscitation and control of bleeding. To assess this technique, a prospective study was performed on twenty normal non-bleeding parturients. The abdominal aorta was compressed by firm pressure with a closed fist just above the umbilicus. Leg and arm arterial blood pressures were measured and femoral artery pulsation felt before, during and after compression. Leg blood pressure was completely obliterated in 55% and significantly reduced (P < 0.01) in a further 10% of subjects. All of these subjects with reduced or absent leg blood pressure also had obliteration of the femoral pulse with compression. Systemic arterial blood pressure was not significantly elevated by successful aortic occlusion. Discomfort with the manoeuvre was significantly increased (P < 0.05) in the group of subjects that had successful aortic occlusion. It is recommended that external aortic compression be considered in severe life-threatening postpartum haemorrhage, particularly during stabilisation or transport of the patient. This simple manoeuvre may be used as an adjunct to other measures and could prove of benefit, especially in locations or situations where advanced medical assistance is geographically or temporally removed.

In 13 healthy volunteers a computerized experimental set-up was used to measure the electrical impedance of the upper arm at changing cuff pressure, together with the finger arterial blood pressure in the contralateral arm. On the basis of a model for the admittance response, the arterial blood volume per centimeter length (1.4 +/- 0.3 ml/cm), the venous blood volume as a percentage of the total blood compartment (49.2 +/- 12.6%), and the total arterial compliance as a function of mean arterial transmural pressure were estimated. The effective physiological arterial compliance amounted to 2.0 +/- 1.3 microliters.mmHg-1.cm-1 and the maximum compliance to 33.4 +/- 12.0 microliters.mmHg-1.cm-1. Additionally, the extravascular fluid volume expelled by the occluding cuff (0.3 +/- 0.3 ml/cm) was estimated. These quantities are closely related to patient-dependent sources of an unreliable blood pressure measurement and vary with changes in cardiovascular function, such as those found in hypertension. Traditionally, a combination of several methods is needed to estimate them. Such methods, however, usually neglect the contribution of extravascular factors.

Background: In developed countries, 16 percent of maternal deaths were attributed to hypertensive disorders. Of hypertensive disorders, the preeclampsia syndrome, either alone or superimposed on chronic hypertension, is the most dangerous. The incidence of preeclampsia in nulliparous populations ranged from 3 to 10 percent.Methods: The present study was conducted at Government Raja Mirasudhar Hospital, Thanjavur Medical College, Thanjavur, Tamil Nadu, India from October 2017 to October 2018. The study consisted of 100 antenatal women with non-severe preeclampsia. The efficacy of labetalol verses nifedipine in its management was studied along with the fetomaternal outcome.Results: In this study, in the labetalol and in the nifedipine groups adequate control of blood pressure was achieved. However, labetalol was well tolerated by our women without much side effects.Conclusions: The present study indicates both labetalol and nifedipine are equally efficacious in the control of hypertension in non-severe preeclampsia. Pathology of the disease was not altered significantly in both the groups. There was no significant difference in the neonatal outcome between the two groups.

1. Twenty-four hour urinary albumin excretion rate was measured by a sensitive radioimmunoassay in 99 male and 100 female randomly selected factory workers, aged between 20 and 60 years. 2 The median (range) albumin excretion rates for men and women of 4.67 (1.0–25.8) and 5.25 (0.2–33.0) mg/24 h, respectively, were not significantly different. 3. No correlation was established between diastolic, systolic or mean arterial blood pressure and albumin excretion rate for the whole group. 4. Twenty-eight subjects with systolic and/or diastolic blood pressures ≥ 140/90 mmHg (18.7/12.0 kPa) showed a positive correlation between mean arterial blood pressure and albumin excretion rate (r = 0.412,P < 0.01). 5. There was no significant relationship between number of cigarettes smoked, age or alcohol intake and albumin excretion rate. 6. The data suggest that in the general population albumin excretion rate is variable and not dependent on blood pressure, but at blood pressures > 140/90 mmHg (18.7/12.0 kPa) albumin excretion rate may become pressure dependent, although high albumin excretion rates were sometimes found in subjects with blood pressures < 140/90 mmHg (18.7/12.0 kPa).

Body Resistance

The effects of resistance training on arterial blood pressure and muscle sympathetic nerve activity (MSNA) at rest have not been established. Although endurance training is commonly recommended to lower arterial blood pressure, it is not known whether similar adaptations occur with resistance training. Therefore, we tested the hypothesis that whole body resistance training reduces arterial blood pressure at rest, with concomitant reductions in MSNA. Twelve young [21 ± 0.3 (SE) yr] subjects underwent a program of whole body resistance training 3 days/wk for 8 wk. Resting arterial blood pressure ( n = 12; automated sphygmomanometer) and MSNA ( n = 8; peroneal nerve microneurography) were measured during a 5-min period of supine rest before and after exercise training. Thirteen additional young (21 ± 0.8 yr) subjects served as controls. Resistance training significantly increased one-repetition maximum values in all trained muscle groups ( P < 0.001), and it significantly decreased systolic (130 ± 3 to 121 ± 2 mmHg; P = 0.01), diastolic (69 ± 3 to 61 ± 2 mmHg; P = 0.04), and mean (89 ± 2 to 81 ± 2 mmHg; P = 0.01) arterial blood pressures at rest. Resistance training did not affect MSNA or heart rate. Arterial blood pressures and MSNA were unchanged, but heart rate increased after 8 wk of relative inactivity for subjects in the control group (61 ± 2 to 67 ± 3 beats/min; P = 0.01). These results indicate that whole body resistance exercise training might decrease the risk for development of cardiovascular disease by lowering arterial blood pressure but that reductions of pressure are not coupled to resistance exercise-induced decreases of sympathetic tone.
