Background Colloids are thought to sustain blood pressure and cardiac index better than crystalloids. However, the relative effects of intraoperative hydroxyethyl starch and crystalloid administration on the cardiac index and blood pressure remain unclear. This study therefore tested in this subanalysis of a previously published large randomized trial the hypothesis that intraoperative goal-directed colloid administration increases the cardiac index more than goal-directed crystalloid administration. Further, the effects of crystalloid and colloid boluses on blood pressure were evaluated. Methods This planned subanalysis of a previous trial analyzed data from 973 patients, of whom 480 were randomized to colloids and 493 were randomized to crystalloids. Fluid administration was guided by esophageal Doppler. The primary outcome was the time-weighted average cardiac index during surgery between the colloid and crystalloid group. The secondary outcomes were the cardiac index just after bolus administration, time elapsed between boluses, and the average real variability during surgery. The study recorded cardiac index, corrected flow time, and blood pressure at 10-min intervals, as well as before and after each bolus. Results Time-weighted average of cardiac index over the duration of anesthesia was only slightly greater in patients given colloid than crystalloid, with the difference being just 0.20 l · min–1 · m–2 (95% CI, 0.11 to 0.29; P < 0.001). However, the hazard for needing additional boluses was lower after colloid administration (hazard ratio [95% CI], 0.60 [0.55 to 0.66]; P < 0.001) in a frailty time-to-event model accounting for within-subject correlation. The median [quartiles] number of boluses per patient was 4 [2, 6] for colloids and 6 [3, 8] for crystalloids, with a median difference (95% CI) of –1.5 (–2 to –1; P < 0.001). The average real mean arterial pressure variability did not differ significantly between the groups (difference in means [95% CI] of –0.03 (–0.07 to 0.02) mmHg, P = 0.229). Conclusions There were not clinically meaningful differences in the cardiac index or mean pressure variability in patients given goal-directed colloid and crystalloids. As might be expected from longer intravascular dwell time, the interval between boluses was longer with colloids. However, on a case basis, the number of boluses differed only slightly. Colloids do not appear to provide substantial hemodynamic benefit. Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New

Objective This study aimed to detect which of the two main medicines suggested in the treatment of postligation cardiac syndrome (PLCS)—dobutamine or mirinone—possesses a more therapeutic effect. While doing this, clinicians are provided with a broader perspective on the treatment and follow-up of cases. The desire was to increase the treatability and monitor ability of the cases in question and hence their survivability. Study Design A retrospective review of a cohort of infants with PLCS was conducted between March 2012 and December 2018. In the treatment of infants with PLCS, dobutamine (dobutamine study group-DSG) or milrinone (milrinone study group-MSG) was used. The respiration, cardiac, echocardiography, and perfusion parameters of the cases were assessed both before and after ligation. Based on the data obtained, both the effects of the medicines on PLCS and the difference between their therapeutic effects were studied. The accuracy of prognostication was assessed with receiver operating characteristic analyses. Results PLCS was detected in 29 (34.1%) of 85 patent ductus arteriosus ligation cases in total. Of all the PLCS cases, 13 (44.8%) were treated with dobutamine and 16 (55.2%) with milrinone. It was observed that the effects of the medicines on the respiratory system and cardiovascular system manifested in the third and 6th hour, respectively. It was detected that both medicines had more effect on the systolic blood pressure (SBP) (area under the curve [AUC]: 0.997/0.996, p = 0.001/0.002) than on the diastolic blood pressure (AUC: 0.911/0.843, p = 0.032/0.046). Conclusion Dobutamine and milrinone, two primary medicines that can be used in the treatment of cases with PLCS, possess similar therapeutic effects on this pathology. In addition, their postoperative therapeutic effects on the SBP are more in the foreground.

In a study to assess the potential effect of nonpulsatile hypothermic cardiopulmonary bypass (CPB), intramucosal pH (pHi) of the gastric and colonic mucosae was determined by tonometry ( n = 8). During the hypothermic phase of CPB, gastric and colonic pHi did not change significantly. Forty minutes after the start of rewarming, despite increases in the cardiac index and mean arterial blood pressure, gastric pHi fell from 7.53 ± 0.02 to 7.31 ± 0.03 ( p = 0.017) and colonic pHi fell from 7.50 ± 0.02 to 7.32 ± 0.03 ( p = 0.028). Forty minutes after the end of CPB both the colonic ( p = 0.017) and gastric ( p = 0.046) pHi remained depressed below pre-CPB values. The difference in the arterial (pHa) and the gastric mucosal pH changed from -0.097 before CPB to 0.016, 40 minutes after the end of CPB ( p = 0.027). This alteration in the pHa-pHi underlines the importance of measuring intramucosal pH by tonometry, since the pHa and pHi may move in opposite directions during episodes of haemodynamic stress. Both the gastric and colonic pHi were found to have a linear correlation with the pHa, although changes in the gastric pHi ( r = 0.41, p = 0.018) were more strongly correlated with the pHa than the colonic pHi ( r = 0.23, p = 0.19) in the rewarming phase of CPB and the immediate post-CPB period when there was a tendency towards intramucosal acidosis. The development of intramucosal acidosis in the rewarming and immediate post-CPB phases following hypothermic nonpulsatile CPB may impair the gut barrier and predispose patients to the absorption of luminal toxins.

In physiology, the mean arterial pressure is defined as an average pressure during one or several cardiac cycles. When calculus is not used, the mean pressure is approximately calculated as the diastolic pressure plus one third of the pulse pressure. In this article it is demonstrated that, when ventricular systolic work is concerned, the above definition of mean pressure must be replaced by a weighted average during the ejection phase of the systole. This gives a formula, by which a much higher estimate of the mean pressure is obtained.

Adrenomedullin is a potent vasodilator with established cardio-protective potentials when the body is exposed to stress. Sympathetic autonomic stress can lead to systolic (SBP) and diastolic blood pressure (DBP) reactivity which is a predictor of stroke. This study was to determine the effect of Adrenomedullin on cardiovascular response to sympathetic autonomic stress using the Cold Pressor Test in normotensive (NT) and hypertensive (HT) adults. Cardiovascular response to the CPT was measured among 30 NT and 30 HT participants, via blood pressure and heart rate before and after exposure to the cold pressor test (CPT). Plasma Adrenomedullin (ADM) was also determined by means of ELISA. Data were expressed as mean±S.E.M and statistical significance was accepted at 95% confidence interval. Exposure to CPT led to significant increases in SBP and DBP in both NT and HT participants with greater effect in HT (p<0.0001). Plasma Adrenomedullin was significantly higher among the NT but the difference on effect of response to CPT in both groups of participants was not significant. There was a negative and insignificant correlation between the ADM level and change in SBP and DBP among the NT participants but a positive and insignificant correlation with both SBP and DBP among the HT participants. We conclude that plasma Adrenomedullin may prevent the development of hypertension in black individuals.

Background: It is well known that meditation improves the physical and psychological condition of its practitioners. This study investigated the heart rate variability response of meditation practitioners in two Chan master teaching environments, namely face-to-face and video classes. Methods: Experimental sessions were conducted, one featuring face-to-face classes and the other featuring video classes. The difference in participants’ physiological parameters (blood pressure and heart rate variability) between the two experimental sessions was determined. In the first session, physiological parameters were recorded twice, before and after one teaching course, and the second session took place one month after the first. The first and second sessions had 45 and 27 participants, respectively. Those involved in the first experiment had no experience with meditation, whereas participants in the second experiment had practiced meditation for an average of 9 years (range = 1 to 27 years). Both experiments were conducted once a week, with each session lasting 1.5 h. Results: For both experiments, both heart rate and heart rate variability by age significantly decreased after one teaching course. Conclusions: Chan meditation practitioners benefit from receiving both face-to-face and video class teaching from a Chan master.

This randomized trial aimed to compare the safety and efficacy of the GAGLESS mouthpiece for esophagogastroduodenoscopy (EGD) with that of the conventional mouthpiece. In all, 90 participants were divided into the GAGLESS mouthpiece and conventional mouthpiece groups. The primary endpoint was the severity of pain using the visual analog scale (VAS), and secondary endpoints were examination time, past history of endoscopy, success of the procedure, systolic (SBP) and diastolic (DBP) blood pressure, oxygen saturation, pulse rate before and after EGD, and adverse events. Endoscopy was completed in all cases, and no complications were observed. VAS, when passing the scope through the pharynx, was 2.5 ± 2.4 and 2.0 ± 1.9 cm (p = 0.24) in the conventional and GAGLESS groups, respectively, and that, throughout the examination, was 2.5 ± 2.4 and 1.7 ± 1.5 cm (p = 0.06), respectively. The difference in blood pressure between the GAGLESS and conventional groups was not significant for SBP (p = 0.08) and significant for DBP (p = 0.03). The post-EGD difference in DBP was significantly lower in the GAGLESS group than in the conventional group. The results indicate that GAGLESS mouthpieces had a lower VAS during endoscopy than the conventional mouthpieces, and the changes in blood pressure were smaller with the GAGLESS mouthpiece.

AbstractBackgroundThe vital signs reflect the physiological state of patients in various clinical conditions. The purpose of this study was to compare the effects of cold compress and Xyla-P cream on hemodynamical changes during venipuncture in hemodialysis patients.Methods and MaterialIn this clinical trial study, 50 patients under hemodialysis were selected by simple random sampling. The patients were then randomly assigned to either Xyla-P cream, cold compress or placebo groups. The vital signs (blood pressure and pulse) were measured upon two intermittent hemodialysis sessions before and after venipuncture. Data were analyzed using repeated measures analysis of variance.ResultsThe mean alternation in systolic blood pressure was significantly different comparing the placebo and cold compress groups before and after intervention (p<0.001). However, the difference was not significant between the Xyla-P cream group and either placebo (p=0.402) or ice compress (p=0.698) groups. The difference of the mean diastolic blood pressure was significant comparing the placebo group with either the Xyla-P cream group (p=0.003) or cold compress group (p<0.001) before and after intervention. In addition, there was a significant difference in the mean number of heartbeats comparing the control group with either the Xyla-P cream group (p<0.001) or cold compress group (p<0.001) before and after the intervention.ConclusionsConsidering the beneficial effects of ice compress and the Xyla-P cream on reduction of cardiovascular parameters, it is recommended to use these methods in hemodialysis patients during venipuncture.
