Pediatric Laparoscopy

Adaptive changes in oxygenation and hemodynamics are evaluated during pediatric laparoscopy. The children underwent laparoscopy (LAP Group, n=20) or open surgery (Open Group, n=10). Regional cerebral (rScO2) and peripheral oxygen saturation (SpO2), heart rate (HR), diastolic (DP) and systolic pressure (SP) were monitored at different intervals: basal (T0); anesthesia induction (T1); CO2PP insufflation (T2); surgery (T3); CO2PP cessation (T4); before extubation (T5). At T1, in both the LAP and Open groups significant changes in rScO2, DP and SP were recorded compared with T0; a decrease in SatO2 was also observed at T5. In the LAP group, at T2, changes in HR related to CO2PP pressure and in DP and SP related to IAP were noted; at T4, a SP change associated with CO2PP desufflation was recorded. Open group, at T3 and T5 showed lower rScO2 values compared with T1. Pneuperitoneum and anesthesia are influent to induce hemodynamics changes during laparoscopy.

The Face

Abstract Background: Face masks are an effective, non-pharmacological strategy to reduce the transmission of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and other pathogens. However, it is a challenge to keep masks sealed during exercise, as ventilation can increase from 5-10 L/min at rest to up to 200 L/min so that masks may be blown away from the face. To reduce leakage e.g. during exercise, a face mask was developed that is taped onto the face. The aim of this study was to investigate during a graded cycle ergometry test the effect of a taped mask on the perception of breathlessness, heart rate, lactate, and oxygen saturation when compared to a surgical mask and no mask.Methods: Four trained and healthy males and females each (n=8 in total) performed incremental cycle ergometer tests until voluntary exhaustion under three conditions: (1) No mask/control, (2) surgical mask or (3) taped mask. During these tests, we measured perception of breathlessness, heart rate, the concentration of blood lactate and peripheral oxygen saturation and analysed the resultant data with one or two-way repeated measures ANOVAs. We also used a questionnaire to evaluate mask comfort and analysed the data with paired t-tests. Results: When compared to wearing no mask, a taped face mask significantly reduces the maximal workload in a graded exercise test by 12±6% (p=0.001). Moreover, with a taped face mask, subjects perceive severe breathlessness at 12±9% lower workload (p=0.012) and oxygen saturation at 65% of the maximal workload is 1.5% lower (p=0.018) when compared to wearing no mask. Heart rate and the concentration of lactate were not significantly different at any workload. When compared to wearing a surgical mask, wearing a taped face mask has a significantly better wearing comfort (p=0.038), feels better on the skin (p=0.004), there is a lower sensation of moisture (p=0.026) and wearers perceive that less heat is generated (p=0.021). We found no sex/gender differences for any parameters. Conclusions: A taped mask is well tolerated during light and moderate exercise intensity but reduces maximal exercise capacity.

Abstract Background: Our goal is to investigate the use of the Oxygen Reserve Index (ORi) and its relation with peripheral oxygen saturation, perfusion index (PI), and pleth variability index (PVI) during one-lung ventilation (OLV).Methods: Fifty patients undergoing general anesthesia and OLV for elective thoracic surgeries were enrolled in an observational cohort study in a tertiary care teaching hospital. During general anesthesia induction, propofol, fentanyl, and rocuronium at appropriate doses were administered intravenously. All patients required OLV after a left-sided double-lumen tube insertion during intubation. Hypoxemia during OLV was defined as peripheral oxygen saturation (SpO2) value of less than 95% when the inspired oxygen fraction (FiO2) is above 60% on a pulse oximetry device. ORi, pulse oximetry, PI, and PVI were measured continuously. Sensitivity, specificity, positive and negative predictive values, likelihood ratios, and accuracy were calculated for ORi equals zero in different anesthesia time points to predict hypoxemia. At Clinicaltrials.gov registry, the Registration ID is NCT05050552.Results: The accuracy for predicting hypoxemia during anesthesia induction at ORi value equals zero at five minutes after intubation in the supine position (DS5) showed a sensitivity of 92.3% (95% CI 84.9-99.6), specificity of 81.1% (95% CI 70.2-91.9), and an accuracy of 84.0% (95% CI 73.8- 94.2). ORi and SpO2 correlation was found at DS5 (p = 0.044), 5 minutes after lateral position with two-lung ventilation (DL5) (p = 0.039), and at 10 minutes after OLV (OLV10)(p = 0.011).Conclusions: ORi equals zero at the time point of five minutes after tracheal intubation in the supine position (DS5) showed high sensitivity and specificity for predicting hypoxemia at a less than 95% value.

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.

Abstract Introduction: The Kangaroo Mother Care (KMC) method is a significant neonatal alternative that ensures better quality humanized care for preterm and low birth weight newborns. Objective: To analyze the immediate physiological effects of the kangaroo position in critically ill newborns. Methods: Open clinical trial with parallel interventions, involving preterm (up to 28 days old) low or very low birth weight newborns (minimum weight of 1,250 grams) of both sexes, that were clinically stable and undergoing enteral nutrition. The degree of respiratory distress was assessed and quantified using the Silverman-Anderson scoring system. Heart rate and peripheral oxygen saturation were collected using a pulse oximeter. Respiratory rate was determined by auscultation for one minute. The newborns were submitted to the kangaroo position once only, for 90 minutes. Results: Participants were 30 newborns, 56.7% of which were girls. Comparison of the variables before and after application of the kangaroo position using the Wilcoxon test showed a statistically significant reduction in respiratory rate (p = 0.02) and Silverman-Anderson score (p < 0.01). The remaining variables showed no significant differences: heart rate (p = 0.21), peripheral oxygen saturation (p = 0.26) and axillary temperature (p = 0.12). Conclusion: There was a decline in the respiratory rate and Silverman-Anderson score after application of the kangaroo position, while peripheral oxygen saturation, axillary temperature and heart rate remained stable.

Abstract Objectives This study aimed to investigate hemodynamic changes in healthy adult patients during different dental procedures and evaluate whether these changes were associated with patients' dental anxiety. Materials and Methods A convenience sample of 119 patients of both genders undergoing routine dental care participated in the study. Participants responded to the Arabic version of the modified dental anxiety scale (MDAS) and a self-structured questionnaire. Each patient had their blood pressure, heart rate, and oxygen saturation measured at three points: before, during, and after the dental procedure using an electronic sphygmomanometer. MDAS scores were categorized into no anxiety, mild, moderate or severe anxiety, while readings of heart rate and blood pressure were categorized into no change, increased or decreased and either “no change” or “increased” for oxygen saturation. Chi-square test was used to investigate the association between the study variables and a p value of < 0.05 was considered statistically significant. SPSS version 20 was used in the analysis. Results Mean ( ± standard deviation [SD]) of MDAS was 11.12 ( ±  3.9) an indicative of moderate dental anxiety. No changes in blood pressure, heart rate, or in oxygen saturation were observed on 39.5%, 54.6% and 97.5% among the study participants, respectively. Half of the participants avoided dental care, with dental anxiety being the main reason for that (26.1%). Pattern of dental visits was significantly associated with MDAS scores (p = 0.042). There were significant changes in blood pressure (p = 0.0003), heart rate (p = 0.01) but not in oxygen saturation (p = 0.33). Changes in blood pressure, heart rate, and oxygen saturation were not associated with dental anxiety p = 0.15, 0.10, and 0.99, respectively. Conclusion The results of this study indicate that the type of dental procedure may cause dental anxiety and cause hemodynamic changes. Therefore, close monitoring of patients with dental anxiety during the treatment is advised.

Short Term Effects

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.

Post Exercise Recovery

Global Proprioceptive Resonance (GPR) is a recently developed approach conceived to solicit the various cutaneous mechanoreceptors, through application of mechanical multifocal vibration at low amplitude and at definite body sites, limiting the stimulation of the profound structures. This interventional study evaluated the effects of GPR on cardiorespiratory function during the post-exertional recovery period. A group of volunteers involved in Triathlon (a multisport discipline consisting of sequential swim, cycle, and run disciplines higly demanding in terms of metabolic engagment), underwent two maximal incremental exercise tests until exhaustion followed alternatively to (a) a 13 minutes section of GPR or (b) a standard low intensity exercise acute trend of the same duration. These effects of these two approaches were compared in terms of recovery of: heart rate (HR), respiratory rate (RR), peripheral oxygen saturation (SpO2) and venous lactate concentration (Lac). The physiological parameters (HR, RR, SpO2 and Lac) recorded in the pre-exertion session showed similar values between the 40 volunteers while several differences were recorded in the post-exertion phase. After 6 min of GPR recovery it was recorded a drop in RR below baseline (19.4±4.15 min-1 vs. 12.2± 0.4 min-1; p<0.001) coupled with an increase in peripheral oxygen saturation above the baseline (GPR: 99.0%±0.16% vs. 96.6%±0.77%, p<0.001). Moreover, the most striking result was the drop in lactate concentration measured after 13 min of GPR recovery: 84.5±3.5% in GPR vs 2.9±7.6% reduction in standard recovery (p<0.001). Notably no differences were recorded recovery of heart rate. GPR has promising effects on post-exercise recovery on RR, SpO2 and lactate level on young athletes.
