Introduction: the corporal hygiene of the preterm newborn, although it is a recommended and routine practice, requires caution and safety for provoking disorganization in the autonomic system and homeostasis imbalance. Aim: to evaluate the variation of heart rate, oxygen saturation and salivary cortisol levels of preterm newborns submitted to conventional immersion baths and swaddled in sheets. Method: this is a randomized, pilot, cross-over clinical trial with 15 clinically stable preterm newborns. Results: the mean heart rate and oxygen saturation after the conventional immersion bath and swaddled in sheet did not present significant clinical and statistical differences. There was an increase in the salivary cortisol concentration when comparing the pre and post-bath values in the two bath techniques. Conclusion: there were no significant differences in stress biomarkers when comparing the two bathing techniques.

Background. In the neonatal intensive care unit (NICU) environment, preterm newborns are subject to environmental stress and numerous painful interventions. It is known that hydrokinesiotherapy promotes comfort and reduces stress because of the physiological properties of water.Objective. To evaluate the short-term effects of hydrokinesiotherapy on reducing stress in preterm newborns admitted to the NICU.Materials and Methods. Fifteen preterm newborns underwent salivary cortisol measurement, pain evaluation using the Neonatal Infant Pain Scale (NIPS), and heart rate, respiratory rate, and peripheral oxygen saturation measurements before and after the application of hydrokinesiotherapy.Results. The mean gestational age of the newborns was34.2±1.66weeks, and the mean weight was1823.3±437.4 g. Immediately after application of hydrokinesiotherapy, a significant reduction was observed in salivary cortisol(p=0.004), heart rate(p=0.003), and respiratory rate(p=0.004)and a significant increase was observed in peripheral oxygen saturation(p=0.002). However, no significant difference was observed in the NIPS score(p>0.05).Conclusion. In the present study, neonatal hydrotherapy promoted short-term relief from feelings of stress. Neonatal hydrokinesiotherapy may be a therapeutic alternative. However, this therapy needs to be studied in randomized, crossover, and blinded trials. This trial is registered withNCT02707731.

AbstractThis study consisted of two experiments. In experiment 1, stress responses of sheep which were restrained either in a laparoscopy cradle or a roll-over cradle were compared. The results of this experiment indicated that restraint in roll-over cradle is less (P < 0·05) stressful than that in a laparoscopy cradle when assessed in terms of the elevation and duration of both the mean heart rate and plasma cortisol responses. Experiment 2 compared the stress responses of sheep subjected to restraint in a laparoscopy cradle, restraint in a laparoscopy cradle with intrauterine artificial insemination (AI) by laparoscopy, minimal restraint with cervical AI or restraint in a roll-over cradle plus foot-trimming. All treatments resulted in significant elevations in both heart rate and plasma cortisol concentrations (F < 0·001). The peak heart rate was significantly (P < 0·05) higher in ewes subjected to cervical AI than in those subjected to intrauterine insemination, with other treatments intermediate. The peak cortisol response did not differ among different treatments. The duration over which both the mean heart rate and -plasma cortisol concentrations remained significantly elevated above pre-treatment concentrations did not differ among treatment groups. The results of this study suggest that while restraint using a laparoscopy cradle is more stressful than that using a rollover cradle, the stress inflicted by intrauterine insemination by laparoscopy itself is no greater than that due to restraint using the laparoscopy cradle alone, cervical AI or the management practice offoot-trimming using a rollover cradle.

To assess the effects of ouabain on pressor and vasoactive hormone responsiveness, 10 healthy volunteers were pretreated with ouabain (0.5 mg i.v. 42 and 18 h before study) or placebo before pressor challenge with angiotensin II (ANG II; 2, 4, and 8 ng.kg-1.min-1 for 30 min/dose) and norepinephrine (NE; 5, 15, and 45 ng.kg-1.min-1 for 15 min/dose). There were no differences at baseline between the two study days regarding mean arterial pressure (MAP) or heart rate. Baseline pulse pressure, however, was significantly greater after ouabain (47 +/- 3 vs. 41 +/- 1 mmHg; P < 0.05). The mean maximum increments in MAP during ANG II and NE infusions were 17.5 +/- 1.1 and 10.5 +/- 1.3 (SE) mmHg, respectively, after ouabain and 19.2 +/- 1.3 and 10.4 +/- 1.5 mmHg after placebo (not significant). The mean heart rate was lower during both infusion periods on the ouabain study day compared with control (P < 0.05). Baseline plasma levels of ANG II, aldosterone, plasma renin activity, atrial and brain natriuretic peptide, guanosine 3',5'-cyclic monophosphate, NE, and epinephrine and achieved levels during the two infusions were similar on the two study days. We conclude that short-term ouabain administration does not alter pressor responsiveness or plasma levels of vasoactive hormones in healthy volunteers.

Anaesthesia of 2 five-year-old femaleAfrican elephants (Loxodonta africana) was required for dental surgery. The animals were each premedicated with 120 mg of azaperone 60 min before transportation to the hospital. Before offloading, 1 mg etorphine was administered intramuscularly (i.m.) to each elephant to facilitate walking them to the equine induction / recovery room. For induction, 2 mg etorphine was administered i.m. to each animal. Induction was complete within 6 min. Surgical anaesthesia was induced with halothane-in-oxygen after intubation of the trunk. During surgery the mean heart rate was 61 and 45 beats / min respectively. Systolic blood pressures increased to 27.5 and 25.6 kPa respectively, and were treated with intravenous azaperone. Blood pressure decreased thereafter to a mean systolic pressure of 18.1 and 19.8 kPa, respectively. Rectal temperature was 35.6 and 33.9 oC at the onset of surgery, and decreased to 35.3 and 33.5 oC, respectively, at the end of anaesthesia. Etorphine anaesthesia was reversed with 5mg diprenorphine at the completion of 90 min of surgery.

Mean Heart Rate

The normal heart rate of young breathing harbor seals, 130.1 beats/min (S.E.M. = 22, n = 33), decreases by 50% during periods of spontaneous apnea in air and by 69% during 2 min of forced apnea in air. Apneic bradycardia develops five times more slowly than bradycardia observed during immersion. During forced apnea the heart rate drops to 31% of the value observed during periods of breathing in 200 s while during immersion the heart rate drops to this value only after 20 s. Since the bradycardia during apnea has a slower time course, apnea alone cannot account for the bradycardia observed during immersion.In quietly resting seals, the apneustic breathing pattern consisted of periods of breathing (duration of 10–115 s) interrupted by apneic pauses (duration of 19–104 s). During the breathing periods successive breaths tended to be smaller so that at the end of a breathing period the mean amplitude of a respiratory movement was only 57% of the mean amplitude of the first inspiration. Tracheostomy altered the breathing pattern and lowered the mean heart rate during breathing to 43% of the rate observed in intact animals. Under controlled conditions immersion bradycardia was highly reproducible and showed no signs of conditioning to the experimental regime. Data from 56 immersions on three animals illustrated minor individual differences in the time course of the immersion bradycardia and provided the basis for an estimate of the average time course of immersion bradycardia in young harbor seals.

The ECG findings before, during and following 81 spontaneous attacks of cluster headache in 24 patients have been recorded using a Holter cardiography system. No significant change in mean heart rate was found during attacks, when all attacks were considered as a group. Attacks which began when patients were awake differed from those which began during sleep as regards changes in mean heart rate. The mean heart rate decreased during the majority (61%) of attacks which began when patients were awake, whereas it remained unchanged or increased during the majority (67.5%) of attacks which began during sleep. The attacks which began when patients were awake also had higher absolute mean heart rate values before, during and following attacks compared to similar values for those attacks which began during sleep. Blood pressure was measured during 11 attacks and showed a significant increase in both systolic and diastolic blood pressure. The heart rate and blood pressure in six patients usually increased during induced head pain.

The South Georgian shag (Phalacrocorax georgianus) shows a remarkable diving ability comparable to that of penguins, yet nothing is known of the physiology of these birds. In this study, heart rates and abdominal temperatures were recorded continuously in four free-ranging South Georgian shags using an implanted data-logger. A time&shy;depth recorder was also attached to the back of the implanted birds to record their diving behaviour. The diving behaviour of the birds was essentially similar to that reported in other studies, with maximum dive durations for individual birds ranging between 140 and 287 s, and maximum depths between 35 and 101 m. The birds, while at the nest, had a heart rate of 104.0&plusmn;13.1 beats min-1 (mean &plusmn; s.e.m.) and an abdominal temperature of 39.1&plusmn;0.2 &deg;C. During flights of 221&plusmn;29 s, heart rate and abdominal temperature rose to 309.5&plusmn;18.0 beats min-1 and 40.1&plusmn;0.3 &deg;C, respectively. The mean heart rate during diving, at 103.7&plusmn;13.7 beats min-1, was not significantly different from the resting values, but the minimum heart rate during a dive was significantly lower at 64.8&plusmn;5.8 beats min-1. The minimum heart rate during a dive was negatively correlated with both dive duration and dive depth. Abdominal temperature fell progressively during a diving bout, with a mean temperature at the end of a bout of 35.1&plusmn;1.7 &deg;C. The minimum heart rate during diving is at a sub-resting level, which suggests that the South Georgian shag responds to submersion with the 'classic' dive response of bradycardia and the associated peripheral vasoconstriction and utilisation of anaerobic metabolism. However, the reduction in abdominal temperature may reflect a reduction in the overall metabolic rate of the animal such that the bird can remain aerobic while submerged.

Background: The transition from a fetus to a newborn is the most complex adaptation that occurs in human experience. This study assessed three physiological parameters viz. temperature (core and peripheral), oxygen saturation and heart rate so as to avoid the delay in normal transitional adaptation.Methods: This cross-sectional observational study was done at Narayana Medical College Hospital, Nellore, Andhra Pradesh, India. A total of 150 neonates born from June 2017 to February 2018 were monitored for heart rate, oxygen saturation, core and peripheral temperature from birth to 60 minutes.Results: Most of the mother’s (45.33%) were aged between 22 to 25 years and the mean age was 23.75±3.64 years. History of consanguineous marriage was noted in 33.33%. The mode of delivery was vaginal in 70.67% of the babies. The mean gestational age was 38.74±1.36 weeks. The birth weight among 62% of the babies was between 2.5 to 3.49 Kgs and mean birth weight was 2.81±0.49 kgs. The meconium stained liquor and requirement of resuscitation was noted in 9.33% and 10.67% respectively.Conclusions: Significant difference was noted with regard to heart rate in babies with active resuscitation, low birth weight (<2.5 kg), meconium stained liquor and warmer care compared to normal babies. There was variation in oxygen saturation in babies who required resuscitation and warmer care, and those who had low birth weight. The mean peripheral and core temperature were different in babies with abdominal care compared to warmer care.
