Icariin mitigates anxiety-like behaviors induced by hemorrhagic shock and resuscitation via inhibiting of astrocytic activation.

BACKGROUND: Abnormal activation of astrocytes in the amygdala contributes to anxiety after hemorrhagic shock and resuscitation (HSR). Nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB)-associated epigenetic reprogramming of astrocytic activation is crucial to anxiety. A bioactive monomer derived from Epimedium icariin (ICA) has been reported to modulate NF-κB signaling and astrocytic activation. PURPOSE: The present study aimed to investigate the effects of ICA on post-HSR anxiety disorders and its potential mechanism of action. METHODS: We first induced HSR in mice through a bleeding and re-transfusion model and selectively inhibited and activated astrocytes in the amygdala using chemogenetics. Then, ICA (40 mg/kg) was administered by oral gavage once daily for 21 days. Behavioral, electrophysiological, and pathological changes were assessed after HSR using the light-dark transition test, elevated plus maze, recording of local field potential (LFP), and immunofluorescence assays. RESULTS: Exposure to HSR reduced the duration of the light chamber and attenuated open-arm entries. Moreover, HSR exposure increased the theta oscillation power in the amygdala and upregulated NF-κB p65, H3K27ac, and H3K4me3 expression. Contrarily, chemogenetic inhibition of astrocytes significantly reversed these changes. Chemogenetic inhibition in astrocytes was simulated by ICA, but chemogenetic activation of astrocytes blocked the neuroprotective effects of ICA. CONCLUSION: ICA mitigated anxiety-like behaviors induced by HSR in mice via inhibiting astrocytic activation, which is possibly associated with NF-κB-induced epigenetic reprogramming.

Restoring microcirculatory perfusion in a preclinical model of severe hemorrhagic shock: The role of microcirculatory function.

BACKGROUND: No reflow in capillaries (no reflow) is the lack of tissue perfusion that occurs once central hemodynamics are restored. This prevents oxygen transfer and debt repayment to vital tissues after shock resuscitation. Since metabolic swelling of cells and tissues can cause no reflow, it is a target for study in shock. We hypothesize no reflow secondary to metabolic cell swelling causes the problem not addressed by current strategies that increase central hemodynamics alone. METHODS: Anesthetized swine were bled until plasma lactate reached 7.5 mM to 9 mM. Intravenous low volume resuscitation solutions were administered (6.8 mL/kg over 5 minutes) consisting of; (1) lactated Ringer (LR), (2) autologous whole blood, (3) high-dose vitamin C (200 mg/kg), or (4) 10% PEG-20k, a polymer-based cell impermeant that corrects metabolic cell swelling. Outcomes were macrohemodynamics (MAP), plasma lactate, capillary flow in the gut and tongue mucosa using orthogonal polarization spectral imaging (OPSI), and survival to 4 hours. RESULTS: All PEG-20k resuscitated swine survived 240 minutes with MAP above 60 mm Hg compared with 50% and 0% of the whole blood and LR groups, respectively. The vitamin C group died at just over 2 hours with MAPs below 40 and high lactate. The LR swine only survived 30 minutes and died with low MAP and high lactate. Capillary flow positively correlated ( p < 0.05) with survival and MAP. Sublingual OPSI correlated with intestinal OPSI and OPSI was validated with a histological technique. DISCUSSION: Targeting micro-hemodynamics in resuscitation may be more important than macrohemodynamics. Fixing both is optimal. Sublingual OPSI is clinically achievable to assess micro-hemodynamic status. Targeting tissue cell swelling that occurs during ATP depletion in shock using optimized osmotically active cell impermeants in crystalloid low volume resuscitation solutions improves perfusion in shocked tissues, which leverages a primary mechanism of injury.

Hypocalcemia in Trauma is Determined by the Number of Units Transfused, Not Whole Blood Versus Component Therapy.

INTRODUCTION: Blood component resuscitation is associated with hypocalcemia (HC) (iCal <0.9 mmol/L) that contributes to coagulopathy and death in trauma patients. It is unknown whether or not whole blood (WB) resuscitation helps mitigate the risk of HC in trauma patients. We hypothesized that calcium homeostasis is maintained and mortality improved in patients who only receive WB. MATERIALS AND METHODS: This is a retrospective review of all adult trauma patients who received WB from July 2018 to December 2020. Variables included transfusions, ionized calcium levels, and calcium replacement. Patients were characterized as follows based on blood products received: WB or WB with other blood components. Groups were compared with respect to HC, correction of HC, 24 h, and inpatient mortality. RESULTS: Two hundred twenty-three patients received WB and met the inclusion criteria. 107 (48%) received WB only. HC occurred in 13% of patients who received more than one WB unit compared to 29% of WB and other blood component patients (P = 0.02). WB patients received less calcium replacement (median 250 mg versus 2000 mg, P < 0.01). HC and total units transfused within 4 h were associated with mortality in the adjusted model. HC significantly increased after 5 units of blood products were transfused, regardless of product type. WB was not protective against HC. CONCLUSIONS: HC and failure to correct HC are significant risk factors for mortality in trauma. Resuscitations with WB only and WB in combination with other blood components are associated with HC especially when more than 5 units of any blood product are transfused. Calcium supplementation should be prioritized in any large volume transfusion, regardless of blood product type.

Quasi-experimental quantitative study of training programme for nurses and midwives regarding provision of neonatal resuscitation in selected governmental hospital, (Sudan), 2018.

AIMS: To measure the effectiveness of educational programmes for nurses regarding knowledge and practice of advanced resuscitation for newborn infants. DESIGN: This is a quasi-experimental study in (Sudan, White Nile state), to evaluate the effectiveness of designed guidelines regarding advanced neonatal resuscitation for midwives during the period November 2020-January 2021. METHODS: Data were collected using two tools: semi-structured questionnaire and checklist. The number of the respondents to the questionnaire is 75 nurses. Statistical analyses were conducted using SPSS (version 22). Data were expressed as percentages. The results show that the level of knowledge is improved significantly after training programme interventions, with safe practice reaching (98.70%) compared with a pre-test percentage of (11.5%). This indicates a steep rise in safe practice after the simulation section, a sharp decrease in unsafe practice after the practical section, followed by subsequent decrease in neonatal mortality rate. This paper has been guided by (STROBE, cohort study) checklist. RESULTS: The study concluded that the majority of nurses and midwives have some knowledge regarding advanced neonatal resuscitation but still, there is a practice gap because of a shortage of facilities and lack of training, However, training programmes do add value on knowledge and practice for nurses and eventually decrease neonatal mortality rate.

Effect of the Helping Babies Breathe Program on Newborn Outcomes: Systematic Review and Meta-Analysis.

Background and objectives: In low- and middle-income countries, the leading cause of neonatal mortality is perinatal asphyxia. Training in neonatal resuscitation has been shown to decrease this cause of mortality. The program "Helping Babies Breathe" (HBB) is a program to teach basic neonatal resuscitation focused on countries and areas with limited economic resources. The aim of the study was to determine the effect of the implementation of the HBB program on newborn outcomes: mortality and morbidity. Material and Methods: A systematic review was carried out on observational studies and clinical trials that reported the effect of the implementation in low- and middle-income countries of the HBB program on neonatal mortality and morbidity. We carried out a meta-analysis of the extracted data. Random-effect models were used to evaluate heterogeneity, using the Cochrane Q and I2 tests, and stratified analyses were performed by age and type of outcome to determine the sources of heterogeneity. Results: Eleven studies were identified. The implementation of the program includes educational strategies focused on the training of doctors, nurses, midwives, and students of health professions. The poled results showed a decrease in overall mortality (OR 0.67; 95% CI 0.57, 0.80), intrapartum stillbirth mortality (OR 0.62; 95% CI 0.51, 0.75), and first-day mortality (OR 0.70; 95% IC 0.64, 0.77). High heterogeneity was found, which was partly explained by differences in the gestational age of the participants. Conclusions: The implementation of the program HBB in low- and medium-income countries has a significant impact on reducing early neonatal mortality.

Trauma-induced hypocalcemia.

BACKGROUND: Trauma-induced hypocalcemia is an underappreciated complication of severe injury but is well known to result in the derangement of an array of physiological regulatory mechanisms. Existing literature provides a compelling link between hypocalcemia and worse trauma-induced coagulopathy and increased mortality after injury. STUDY DESIGN AND METHODS: This narrative review evaluates available data related to the risk factors, mechanisms, and treatment of hypocalcemia after severe injury. The authors did not perform a systemic review or meta-analysis. RESULTS AND DISCUSSION: The interplay of acidosis, hypothermia, and coagulopathy with hypocalcemia potentiates the bloody vicious cycle of hemorrhagic shock which has been the paradigm of trauma resuscitation for over half a century. However, current screening and treatment of postinjury hypocalcemia are relegated to a secondary consideration in trauma resuscitation. We conclude calcium supplementation should be a primary tier intervention for life-threatening injury.

Facility and care provider emergency preparedness for neonatal resuscitation in Kano, Nigeria.

INTRODUCTION: The knowledge, attitude, and practice of emergency neonatal resuscitation are critical requirements in any facility that offers obstetric and neonatal services. This study aims to conduct a needs assessment survey and obtain individual and facility-level data on expertise and readiness for neonatal resuscitation. We hypothesize that neonatal emergency preparedness among healthcare providers in Kano, Nigeria is associated with the level of knowledge, attitudinal disposition, practice and equipment availability at the facility level. METHODS: A semi-structured, self-administered questionnaire was administered to a cross-section of health providers directly involved with neonatal care (n = 112) and attending a neonatal resuscitation workshop in Kano state. Information regarding knowledge, attitude, practice and facility preparedness for neonatal resuscitation was obtained. Bloom's cut-off score and a validated basic emergency obstetric and neonatal care assessment tool were adopted to categorize outcomes. Multivariable logistic regression was employed to determine independent predictors of knowledge and practice. RESULTS: Almost half (48% and 42% respectively) of the respondents reported average level of self-assessed knowledge and comfort during resuscitation. Only 7% (95% CI:3.2-13.7) and 5% (95% CI:2.0-11.4) of health providers demonstrated good knowledge and practice scores respectively, with an overall facility preparedness of 46%. Respondents' profession as a physician compared to nurses and midwives predicted good knowledge (aOR = 0.08, 95% CI: 0.01-0.69; p = 0.01), but not practice. CONCLUSION: Healthcare provider's knowledge and practice including facility preparedness for emergency neonatal resuscitation were suboptimal, despite the respondents' relatively high self-assessed attitudinal perception. Physicians demonstrated higher knowledge compared to other health professionals. The low level of respondents' awareness, practice, and facility readiness suggest the current weak state of secondary health systems in Kano.

Silent voices of the midwives: factors that influence midwives' achievement of successful neonatal resuscitation in sub-Saharan Africa: a narrative inquiry.

BACKGROUND: In Tanzania, birth asphyxia is a leading cause of neonatal death. The aim of this study was to identify factors that influence successful neonatal resuscitation to inform clinical practice and reduce the incidence of very early neonatal death (death within 24 h of delivery). METHODS: This was a qualitative narrative inquiry study utilizing the 32 consolidated criteria for reporting qualitative research (COREQ). Audio-recorded, semistructured, individual interviews with midwives were conducted. Thematic analysis was applied to identify themes. RESULTS: Thematic analysis of the midwives' responses revealed three factors that influence successful resuscitation: 1. Hands-on training ("HOT") with clinical support during live emergency neonatal resuscitation events, which decreases fear and enables the transfer of clinical skills; 2. Unequivocal commitment to the Golden Minute® and the mindset of the midwife; and. 3. Strategies that reduce barriers. Immediately after birth, live resuscitation can commence at the mother's bedside, with actively guided clinical instruction. Confidence and mastery of resuscitation competencies are reinforced as the physiological changes in neonates are immediately visible with bag and mask ventilation. The proclivity to perform suction initially delays ventilation, and suction is rarely clinically indicated. Keeping skilled midwives in labor wards is important and impacts clinical practice. The midwives interviewed articulated a mindset of unequivocal commitment to the baby for one Golden Minute®. Heavy workload, frequent staff rotation and lack of clean working equipment were other barriers identified that are worthy of future research. CONCLUSIONS: Training in resuscitation skills in a simulated environment alone is not enough to change clinical practice. Active guidance of "HOT" real-life emergency resuscitation events builds confidence, as the visible signs of successful resuscitation impact the midwife's beliefs and behaviors. Furthermore, a focused commitment by midwives working together to reduce birth asphyxia-related deaths builds hope and collective self-efficacy.

High Dose Ascorbic Acid During Acute Resuscitation in Critically Burn Patients.

Ascorbic acid (AA) is a potent oxygen-free radical scavenger. We hypothesized that treating severe burn patients with high doses of AA (HDAA) can reduce fluid resuscitation requirements and prevent organ dysfunction. We performed a unicentric, retrospective case-control study of 75 burn patients: 25 patients admitted from 2018 to 2019 with more than 30% Total Surface Body Surface Area (TSBA) burned who received HDAA (66 mg/kg/h as soon as possible after admission until 36 h after injury), and 50 patients admitted from 2014 to 2017 with similar Abbreviated Burn Severity Index (ABSI)/Baux scores who were treated with the same protocol but did not receive HDAA. During the first 24 hours of burn resuscitation the HDAA group required less fluids than the control group (3.06 ± 0.87 ml/kg/%TBSA vs 4.32 ± 1.51 P < .05), but the overall reduction of fluid requirements during the first 72 hours was not significant. There were no significant differences in Sequential Organ Failure Assessment (SOFA), other hemodynamic parameters, complications, or mortality. We also did not find an increase acute kidney injury in patients who received HDAA even though the mean urine oxalate/creatinine ratio was 0.61 (0.02-0.96). We conclude that in severe burn patients treated with a restrictive fluid therapy protocol, administration of HDAA can decrease only the initial fluid requirements but not total fluid intakes. We did not find differences in severity score after resuscitation or in mortality. Nor did we find an increase in renal failure in patients administered with HDAA.

The impact of fluid resuscitation via colon on patients with severe acute pancreatitis.

Severe acute pancreatitis (SAP) is a life-threatening disease. Fluid Resuscitation Via Colon (FRVC) may be a complementary therapy for early controlled fluid resuscitation. But its clinical application has not been reported. This study aims to explore the impact of FRVC on SAP. All SAP patients with the first onset within 72 h admitted to the hospital were included from January 2014 to December 2018 through electronic databases of Ruijin hospital and were divided into FRVC group (n = 103) and non-FRVC group (n = 78). The clinical differences before and after the therapy between the two groups were analyzed. Of the 181 patients included in the analysis, the FRVC group received more fluid volume and reached the endpoint of blood volume expansion ahead of the non-FRVC group. After the early fluid resuscitation, the inflammation indicators in the FRVC group were lower. The rate of mechanical ventilation and the incidence of hypernatremia also decreased significantly. Using pure water for FRVC was more helpful to reduce hypernatremia. However, Kaplan-Meier 90-day survival between the two groups showed no difference. These results suggest that the combination of FRVC might benefit SAP patients in the early stage of fluid resuscitation, but there is no difference between the prognosis of SAP patients and that of conventional fluid resuscitation. Further prospective study is needed to evaluate the effect of FRVC on SAP patients.

The use of vasopressors during acute burn resuscitation.

BACKGROUND: Vasopressors may be required during acute burn resuscitation to support mean arterial blood pressure, but their use is not well-described in the burn literature. The purpose of this study was to examine vasopressor use during acute fluid resuscitation. METHODS: Retrospective review of adults with burns ≥ 20% TBSA admitted to an ABA-verified regional burn center. Patients administered an infusion of a vasopressor for at least 30 min during the 1 st 48 h post-burn formed the PRESSOR group while patients who did not receive vasopressors formed the NoPRESSOR group. RESULTS: We studied 52 burned adults, 85% of which had flame burns. Vasopressors were administered during resuscitation to 31% of patients. Vasopressor infusions began at 20.9 ± 10.9 h post burn and were continued for 16.8 ± 10.8 h. PRESSOR patients (N = 16) had significantly greater total (p = 0.001) and full thickness burn size (p < 0.001), and need for mechanical ventilation (p = 0.005) than NoPRESSOR patients (N = 36). PRESSOR and NoPRESSOR patients did not differ significantly in per cent predicted fluid volume received in the first 24 h (143 ± 58 Vs. 125 ± 46 respectively). PRESSOR patients compared to NoPRESSOR patients tended to have been administered 5% albumin (Alb) less often (38% Vs 47%) and high dose vitamin C (HDVC) more often during resuscitation (69% vs 17%). Multivariate regression analysis found that patient age (OR 1.189, 95% CI: 1.047, 1.351) and HDVC (OR 24.701, 95% CI: 1.558, 391.551) were independently associated with greater use of vasopressors. An inverse probability weighted propensity analysis also identified a significant association between HDVC and increased use of vasopressors (OR 6.902, 95 % CI: 2.503, 19.026), and significantly decreased vasopressor administration following Alb administration (OR 0.310, 95% CI: 0.130, 0.739). CONCLUSION: Advanced age appears to be the most important determinant of vasopressor use during resuscitation. While vasopressor requirements appear to have been increased by HDVC and decreased by Alb, this needs to be formally evaluated in a large randomized study.

A Randomized Trial of Laryngeal Mask Airway in Neonatal Resuscitation.

BACKGROUND: Face-mask ventilation is the most common resuscitation method for birth asphyxia. Ventilation with a cuffless laryngeal mask airway (LMA) has potential advantages over face-mask ventilation during neonatal resuscitation in low-income countries, but whether the use of an LMA reduces mortality and morbidity among neonates with asphyxia is unknown. METHODS: In this phase 3, open-label, superiority trial in Uganda, we randomly assigned neonates who required positive-pressure ventilation to be treated by a midwife with an LMA or with face-mask ventilation. All the neonates had an estimated gestational age of at least 34 weeks, an estimated birth weight of at least 2000 g, or both. The primary outcome was a composite of death within 7 days or admission to the neonatal intensive care unit (NICU) with moderate-to-severe hypoxic-ischemic encephalopathy at day 1 to 5 during hospitalization. RESULTS: Complete follow-up data were available for 99.2% of the neonates. A primary outcome event occurred in 154 of 563 neonates (27.4%) in the LMA group and 144 of 591 (24.4%) in the face-mask group (adjusted relative risk, 1.16; 95% confidence interval [CI], 0.90 to 1.51; P = 0.26). Death within 7 days occurred in 21.7% of the neonates in the LMA group and 18.4% of those in the face-mask group (adjusted relative risk, 1.21; 95% CI, 0.90 to 1.63), and admission to the NICU with moderate-to-severe hypoxic-ischemic encephalopathy at day 1 to 5 during hospitalization occurred in 11.2% and 10.1%, respectively (adjusted relative risk, 1.27; 95% CI, 0.84 to 1.93). Findings were materially unchanged in a sensitivity analysis in which neonates with missing data were counted as having had a primary outcome event in the LMA group and as not having had such an event in the face-mask group. The frequency of predefined intervention-related adverse events was similar in the two groups. CONCLUSIONS: In neonates with asphyxia, the LMA was safe in the hands of midwives but was not superior to face-mask ventilation with respect to early neonatal death and moderate-to-severe hypoxic-ischemic encephalopathy.

Supplement of Lipid Emulsion to Epinephrine Improves Resuscitation Outcomes of Asphyxia-Induced Cardiac Arrest in Aged Rats.

OBJECTIVE: The goal of the study was to investigate the efficacy of lipid supplement to epinephrine-based therapy in resuscitation of asphyxia-induced cardiac arrest in aged rats. METHODS: The study included two parts: in experiment A, rats underwent asphyxial cardiac arrest and cardiopulmonary resuscitation, randomized to receive epinephrine and normal saline (control group, n=22), epinephrine and intralipid 20% (long-chain triglycerides (LCT) group, n=22) or epinephrine and lipovenoes 20% (LCT/medium-chain triglcerides (MCT) group, n=22). Return of spontaneous circulation, recurrence of asystole after resuscitation, hemodynamic metrics, arterial blood gas values, neurological assessment score and indexes of pulmonary transudation were recorded. In experiment B, rats using the same model and resuscitation protocol were randomly divided into 21 groups: Control 0, Control 20, Control 40, Control 60, Control 80, Control 100, Control 120, LCT 0, LCT 20, LCT 40, LCT 60, LCT 80, LCT 100, LCT 120, LCT/MCT 0, LCT/MCT 20, LCT/MCT 40, LCT/MCT 60, LCT/MCT 80, LCT/MCT 100 and LCT 120 (n=10, the subscripts represent respective endpoint of observation in minutes). Myocardial bioenergetics were determined. RESULTS: In experiment A, the LCT and LCT/MCT groups had a shorter time to return of spontaneous circulation (ROSC) (P=0.001and P<0.001, respectively) and higher survival rate (P=0.033 and P=0.014, respectively) compared with the Control group. The LCT/MCT group had higher MAP (P<0.001 and P=0.001, respectively), HR (P<0.001 and P=0.004, respectively) and RPP (P<0.001 and P<0.001, respectively) compared with the Control and LCT groups, respectively. In experiment B, the LCT/MCT group had a higher energy charge compared with the control group at 20 (P<0.001) and 40 (P<0.001) minutes. The LCT group had higher energy charge compared with the Control group at 40 (P<0.001) and 60 (P<0.001) minutes. CONCLUSION: The supplement of lipid emulsion to epinephrine improves resuscitation outcomes of asphyxia-induced cardiac arrest than epinephrine alone in our in vivo model of aged rat. LCT/MCT emulsion may be superior to LCT emulsion in epinephrine-based resuscitation.

Updates in Sepsis Resuscitation.

Sepsis care has evolved significantly since the initial early goal-directed therapy (EGDT) trials. Early fluid resuscitation, source control, and antibiotic therapy remain cornerstones of care but overall understanding is more nuanced, particularly regarding fluid selection, vasopressors, and inotropic support. Timely nutrition therapy and ventilatory support tend to receive less attention but also are important. Recent research has explored immunomodulation, ß-blockade, and vitamin supplementation. A renewed emphasis on early, aggressive resuscitation reaffirms the importance of emergency medicine providers knowledgeable and skilled in sepsis management.

Positive End-Expiratory Pressure in Newborn Resuscitation Around Term: A Randomized Controlled Trial.

BACKGROUND: International guidelines for resuscitation recommend using positive end-expiratory pressure (PEEP) during ventilation of preterm newborns. Reliable PEEP-valves for self-inflating bags have been lacking, and effects of PEEP during resuscitation of term newborns are insufficiently studied. The objective was to determine if adding a new PEEP valve to the bag-mask during resuscitation of term and near-term newborns could improve heart rate response. METHODS: This randomized controlled trial was performed at Haydom Lutheran Hospital in Tanzania (September 2016 to June 2018). Helping Babies Breathe-trained midwives performed newborn resuscitation using self-inflating bags with or without a new, integrated PEEP valve. All live-born newborns who received bag-mask ventilation at birth were eligible. Heart rate response measured by ECG was the primary outcome, and clinical outcome and ventilation data were recorded. RESULTS: Among 417 included newborns (median birth weight 3200 g), 206 were ventilated without and 211 with PEEP. We found no difference in heart rate response. Median (interquartile range) measured PEEP in the PEEP group was 4.7 (2.0-5.6) millibar. The PEEP group received lower tidal volumes (4.9 [1.9-8.2] vs 6.3 [3.9-10.5] mL/kg; P = .02) and had borderline lower expired CO2 (2.9 [1.5-4.3] vs 3.3 [1.9-5.0] %; P = .05). Twenty four-hour mortality was 9% in both groups. CONCLUSIONS: We found no evidence for improved heart rate response during bag-mask ventilation with PEEP compared with no PEEP. The PEEP valve delivered a median PEEP within the intended range. The findings do not support routine use of PEEP during resuscitation of newborns around term.

Effect of acupuncture method of removing-stasisand resuscitating on the consciousness of patients with severe traumatic brain injury: A randomized clinical trial.

INTRODUCTION: With the development of social economy, transportation and various infrastructures have also developed, but it has objectively increased the number of patients with head injury. Although the current craniocerebral medicine technology continues to advance, long-term bed rest and other complications have led to an insignificant decrease in the mortality rate of coma patients. It is not uncommon for patients with disturbance of consciousness caused by head injury in major hospitals. METHODS/DESIGN: This will be a retrospective, single-blind clinical observational study. We will select 50 cases that meet the subject's selection criteria. According to whether they received acupuncture treatment or not, they will be randomly divided into 2 groups, namely treatment group and control group. The control group will be given conventional Western medicine treatment, and the treatment group will be given acupuncture method of removing-stasis and resuscitating treatment on the basis of the control group. DISCUSSION: Our purpose is to observe the role of acupuncture method of removing-stasis and resuscitating in promoting the recovery of patients with severe head injury. We aim to provide more evidence-based medical evidence for acupuncture treatment of this disease. TRIAL REGISTRATION: ClinicalTrials.gov, ChiCTR2000034732, Registered on 19 July 2020.

Enhanced Neonatal Resuscitation Provider Course for Novice Learners.

OBJECTIVE: To study the effect of an enhanced format of the Neonatal Resuscitation Program (NRP) course on new clinicians' comfort level in providing neonatal resuscitation. DESIGN: Pilot project based on the Plan-Do-Study-Act framework with a pretest-posttest design. SETTING/LOCAL PROBLEM: This course was developed in response to an assessment of new NRP clinicians who self-reported low competence and comfort with selected steps of neonatal resuscitation after participating in our system's usual NRP provider course. PARTICIPANTS: A convenience sample of nurses, respiratory therapists, and physicians taking the NRP course. INTERVENTION/MEASUREMENTS: The enhanced-format course facilitated hands-on practice at skills stations before the integrated skills station and simulation/debriefing component. The level of comfort in key areas of neonatal resuscitation was assessed in a postintervention survey on a 4-point Likert scale. RESULTS: After completion of this enhanced-format course, participants reported an increase in comfort level with equipment and selected resuscitation skills. CONCLUSION: An enhanced NRP provider course targeted to the unique learning needs of novice learners may increase their comfort level and satisfaction with newborn resuscitation knowledge and skills.

Basic neonatal resuscitation skills of midwives and nurses in Eastern Ethiopia are not well retained: An observational study.

BACKGROUND: Neonatal resuscitation is a life-saving intervention for birth asphyxia, a leading cause of neonatal mortality. Worldwide, four million neonate deaths happen annually, and birth asphyxia accounts for one million deaths. Improving providers' neonatal resuscitation skills is critical for delivering quality care and for morbidity and mortality reduction. However, retention of these skills has been challenging in developing countries, including Ethiopia. Hence, this study aimed to assess neonatal resuscitation skills retention and associated factors among midwives and nurses in Eastern Ethiopia. METHODS: An institution-based cross-sectional study was conducted using a pre-tested, structured, observational checklist. A total of 427 midwives and nurses were included from 28 public health facilities by cluster sampling and simple random sampling methods. Data were collected on facility type, availability of essential resuscitation equipment, socio-demographic characteristics of participants, current working unit, years of professional experience, whether a nurse or midwife received refresher training, and skills and knowledge related to neonatal resuscitation. Binary logistic regression was used to analyse the association between neonatal resuscitation skill retention and independent variables. RESULTS: About 11.2% of nurses and midwives were found to have retention of neonatal resuscitation skills. Being a midwife (AOR, 7.39 [95% CI: 2.25, 24.24]), ever performing neonatal resuscitation (AOR, 3.33 [95% CI: 1.09, 10.15]), bachelor sciences degree or above (AOR, 4.21 [95% CI: 1.60, 11.00]), and good knowledge of neonatal resuscitation (AOR, 3.31 [95% CI: 1.41, 7.73]) were significantly associated with skill retention of midwives and nurses. CONCLUSION: Basic neonatal resuscitation skills of midwives and nurses in Eastern Ethiopia are not well retained. This could increase the death of neonates due to asphyxia. Being a midwife, Bachelor Sciences degree or above educational status, ever performing neonatal resuscitation, and good knowledge were associated with skill retention. Providers should be encouraged to upgrade their educational level to build their skill retention and expose themselves to NR. Further, understanding factors affecting how midwives and nurses gain and retain skills using high-level methodology are essential.

Blowing Smoke Up Your Arse: Drowning, Resuscitation, and Public Health in Eighteenth-Century Venice.

This article examines resuscitation practices in the second half of the eighteenth century, especially the new use of tobacco smoke enema machines on people who had been extracted from water with no signs of life. Drownings accounted for a small number and proportion of urban deaths, yet governments promoted resuscitation techniques at considerable expense in order to prevent such deaths. The visibility of drowning in religious, urban, and civic life encouraged engagement with new approaches. Analyzing the deployment of resuscitation practices illuminates three key features of premodern public health interventions: the focus of governments on the logistics of these interventions, the participation of physicians and surgeons at all levels of the professional hierarchy, and the importance of communication.

Forgot calcium? Admission ionized-calcium in two civilian randomized controlled trials of prehospital plasma for traumatic hemorrhagic shock.

BACKGROUND: Randomized clinical trials (RCTs) support the use of prehospital plasma in traumatic hemorrhagic shock, especially in long transports. The citrate added to plasma binds with calcium, yet most prehospital trauma protocols have no guidelines for calcium replacement. We reviewed the experience of two recent prehospital plasma RCTs regarding admission ionized-calcium (i-Ca) blood levels and its impact on survival. We hypothesized that prehospital plasma is associated with hypocalcemia, which in turn is associated with lower survival. METHODS: We studied patients enrolled in two institutions participating in prehospital plasma RCTs (control, standard of care; experimental, plasma), with i-Ca collected before calcium supplementation. Adults with traumatic hemorrhagic shock (systolic blood pressure ≤70 mm Hg or 71-90 mm Hg + heart rate ≥108 bpm) were eligible. We use generalized linear mixed models with random intercepts and Cox proportional hazards models with robust standard errors to account for clustered data by institution. Hypocalcemia was defined as i-Ca of 1.0 mmol/L or less. RESULTS: Of 160 subjects (76% men), 48% received prehospital plasma (median age, 40 years [interquartile range, 28-53 years]) and 71% suffered blunt trauma (median Injury Severity Score [ISS], 22 [interquartile range, 17-34]). Prehospital plasma and control patients were similar regarding age, sex, ISS, blunt mechanism, and brain injury. Prehospital plasma recipients had significantly higher rates of hypocalcemia compared with controls (53% vs. 36%; adjusted relative risk, 1.48; 95% confidence interval [CI], 1.03-2.12; p = 0.03). Severe hypocalcemia was significantly associated with decreased survival (adjusted hazard ratio, 1.07; 95% CI, 1.02-1.13; p = 0.01) and massive transfusion (adjusted relative risk, 2.70; 95% CI, 1.13-6.46; p = 0.03), after adjustment for confounders (randomization group, age, ISS, and shock index). CONCLUSION: Prehospital plasma in civilian trauma is associated with hypocalcemia, which in turn predicts lower survival and massive transfusion. These data underscore the need for explicit calcium supplementation guidelines in prehospital hemotherapy. LEVEL OF EVIDENCE: Therapeutic, level II.
