Application of transport ventilator in the inter-hospital transport of critically ill children / 中国当代儿科杂志

OBJECTIVES@#To study the application value of transport ventilator in the inter-hospital transport of critically ill children.@*METHODS@#The critically ill children in Hunan Children's Hospital who were transported with or without a transport ventilator were included as the observation group (from January 2019 to January 2020; n=122) and the control group (from January 2018 to January 2019; n=120), respectively. The two groups were compared in terms of general data, the changes in heart rate, respiratory rate, and blood oxygen saturation during transport, the incidence rates of adverse events, and outcomes.@*RESULTS@#There were no significant differences between the two groups in sex, age, oxygenation index, pediatric critical illness score, course of disease, primary disease, heart rate, respiratory rate, and transcutaneous oxygen saturation before transport (P>0.05). During transport, there were no significant differences between the two groups in the changes in heart rate, respiratory rate, and transcutaneous oxygen saturation (P>0.05). The incidence rates of tracheal catheter detachment, indwelling needle detachment, and sudden cardiac arrest in the observation group were lower than those in the control group during transport, but the difference was not statistically significant (P>0.05). Compared with the control group, the observation group had significantly shorter duration of mechanical ventilation and length of stay in the pediatric intensive care unit and significantly higher transport success rate and cure/improvement rate (P<0.05).@*CONCLUSIONS@#The application of transport ventilator in the inter-hospital transport can improve the success rate of inter-hospital transport and the prognosis in critically ill children, and therefore, it holds promise for clinical application in the inter-hospital transport of critically ill children.

Objective:To study the effects of comprehensive warming intervention strategy on the body temperature of preterm infants (gestational age <32 weeks and birth weight <1 500 g) during inter-hospital transportation.Method:From October 2016 to July 2019, eligible preterm infants transported to our hospital were retrospectively analyzed. From October 2016 to March 2018, preterm infants transported with routine transportation strategy were assigned into the control group. From April 2018 to July 2019, preterm infants transported with the comprehensive warming intervention strategy were assigned into the experiment group. The body temperature, complications and prognosis before and after the transportation to our NICU were compared.Result:A total of 1 194 premature infants with gestational age <32 weeks were included with 630 cases in the control group and 564 cases in the experiment group. No significant differences existed in demographic data of the mothers, infants and the transportation time between the two groups ( P>0.05). The body temperatures before and after transportation in the experimental group were (36.8±0.5)℃ and (36.7±0.5)℃, significantly higher than the control group [(36.0±0.4)℃ and (36.3±0.6)℃] ( P<0.01). The incidences of hypoglycemia and mortality in the experimental group were 3.7% (21/564) and 4.8% (27/564), significantly lower than the control group [8.4% (53/630) and 7.9% (50/630)] ( P<0.05). Conclusion:Comprehensive warming intervention strategy in inter-hospital transport can effectively improve the body temperature of preterm infants before and after transportation, reducing the incidences of hypoglycemia and mortality.

Going and coming from a surgical center: assessing risks in patient transport in a university hospital of Brazil / Indo e vindo de um centro cirúrgico: avaliando riscos no transporte de pacientes em um hospital universitário do Brasil

The patient's in-hospital transport is an activity that must be performed with safety and quality and involves considerable risks, especially for surgical patients. The objective of this study was to evaluate the adequacy or not of transport of surgical patients from inpatient units to surgical centers and vice-versa. The transport and patient profile, the nursing workload, the professionals and conditions involved were assessed for each patient (or transport), and subsequently the transports were evaluated as inadequate (some non-conformity) or adequate. The transport was inadequate in 39.3% of the evaluations. The most commonnon-conformities were the lack of knowledge of the transport at the patient's destination, incorrect documents, patient alone during the route, and absence of health professional during transport (when necessary). In this institution and in the period evaluated, the transport was mainly run by porter. Patients in rout to inpatient units have higher frequency of inadequate transport, mainly because of lack of communication with the destination unit. The increase in workload, evaluated by the Santos Score, also increased the risk of having inappropriate transport (OR = 1.21, CI95%: 1.08-1.16), and when the patients were grouped in minimal care versus non-minimal care, the latter also showed higher risk of inadequate transport. When the transports were evaluated separately by route, patients going to surgical centers had a higher risk when the Santos Score increased (OR = 1.168, CI95%: 1.07-1.27), and patients going to inpatient units had a lower risk when the Santos Score increased (OR = 0.605, CI95%: 0.46-0.80). In the last case, patients with a high workload were also accompanied by health professionals. The presence of a health professional when the patient was going to an inpatient unit also decreased the risk of inadequate transport (OR = 0.011, CI95%: 0.002-0.070). The patient returning to their origin unit showed more transport non-conformities. Perhaps the reason is the discredit attributed to risk in these patients once the surgical problem was solved. Thus, it is a fact that the patient nursing workload and the route of the transport were effective in predicting the risk of inadequate transport, being of great potential for practical use.

O transporte hospitalar do paciente é uma atividade que deve ser realizada com segurança e qualidade e envolve riscos consideráveis, especialmente em pacientes cirúrgicos. O objetivo deste estudo foi avaliar a adequação ou não do transporte de pacientes cirúrgicos da unidade de internação para o centro cirúrgico e vice-versa. O perfil, a carga de trabalho em enfermagem, os profissionais envolvidos no transporte foram avaliados para a cada transporte, então os transportes foram avaliados como inadequados (quando ocorreu qualquer não conformidade) ou não. O transporte foi inadequado em 39,3% das avaliações; as não-conformidades mais comuns foram o desconhecimento do transporte no destino, documentos incorretos, paciente sozinho durante a rota, e a ausência do profissional da saúde (quando necessário). Nesta instituição e no período avaliado, o transporte era principalmente realizado por maqueiros. Pacientes com destino a unidades de internação têm maior frequência de transporte inadequado, principalmente por nenhuma comunicação. Sobre a carga de trabalho, avaliada pela pontuação de Santos, com a carga de trabalho aumentando o risco de ter o transporte inadequado também aumentou (Odds Ratio, OR = 1,21; IC95%: 1,08-1,16), e quando os pacientes foram agrupados em cuidados mínimos versus cuidado não mínimos, os últimos também mostram maior risco de transporte inadequado. Quando os transportes foram avaliados separadamente por rota, o paciente que vai para o centro cirúrgico tem maior risco quando o Score de Santos aumenta (OR = 1,168; IC95%: 1,07-1,27), e os pacientes que vão para a unidade de internação tem menor risco quando o Score de Santos aumenta (OR = 0,605; IC95%: 0,46-0,80). Pacientes no último caso, quando tem alta carga de trabalho também foram acompanhados por profissionais de saúde. A presença de profissionais de saúde quando o paciente vai para a unidade de internação também diminuem o risco (OR = 0,11; IC95%: 0,002-0,07). Quando os pacientes retornam às suas unidades mostram mais riscos de transporte e não-conformidades, talvez a razão é o descrédito atribuído ao risco nesses pacientes, uma vez que o problema cirúrgico foi resolvido. Assim, é fato que a carga de trabalho de enfermagem e a rota do transporte do paciente foram eficaz na predição do risco de transporte inadequado, sendo que apresentam grande potencial para uso prático.

The clinical features of patients: transfered by "Qilu " interhospital transfer center / 中华急诊医学杂志

Objective To explore new models for interhospital transfer and provide theoretical basis for the interhospital transfer system construction through analyzing the clinical features of the patients transfered by "Qilu" interhospital transfer center.Methods Totally 258 patients aged over 18 years who were transferred to or from Qilu Hospital of Shandong University from August 2014 to December 2016 were analyzed.The data including sex,age,transport index,modified early warning score (MEWS) and outcome of patients with successful transport were collected.According to the results,the transferred patients were divided into the improved group and the non-improved group,and the differences of the above indicators between the two groups were analyzed.In the numerical variable analysis,Student's t test or Mann-whitney non-parametric test was applied,and the categorical variable was applied with x2 test.The correlation between clinical indicators and outcomes of the patients was analyzed by logistic regression analysis.Results The total transfer success rate was 98.5％.The transported male patients were more than female patients.Patients transferred to Qilu Hospital were mainly diagnosed with nervous system disease,trauma and circulatory system disease,and patients transferred from QiLu Hospital were respiratory disease,circulatory system disease,and nervous system disease.Tracheal intubation,tracheotomy,and invasive mechanical ventilation rates were 11.9％-22.2％.The patients ratio of transferred from Qilu Hospital with vasoactive drugs and the ratio of patients with deep venous catheter were three times and five times than those transferred to Qilu Hospital.Eighty-one percent patients transferred to Qilu Hospital recovered,and 45.5％ patients transferred from the hospital recovered.The age,heart rate,MEWS score,length of stay,ICU ratio,mechanical ventilation ratio and tracheal intubation ratio were significantly different between the improved group and the non-improved group (P＜0.05).Among the critically patients transferred to ICU,the length of stay was correlated with the outcome of the improvement.(OR=1.213,95％CI:1.085-1.357).Conclusions "Qilu" Interhospital Transfer Center has a high success rate and high recovery rate of patients,and can be a new model for the construction of interhospital transfer system.

The study of extremely low and very low birth weight infant transport risk assessment and factors that influenced deaths / 中国新生儿科杂志

Objective To study the transport risk and factors that influence deaths of very low birth weight (VLBW) and extremely low birth weight (ELBW) infants.Method All infants transferred to our neonatal intensive care unit (NICU) by our hospital transport team or local hospital transport team from January 2014 to December 2015 were included in our study.Their clinical data were retrospectively studied.The risks of transport between hospitals were analyzed.The risk factors of deaths within and after 7 days of admission were further analyzed by multivariate Logistic regression analysis.The receiver operation characteristic (ROC) curve was used to assess the sensitivity and specificity of mortality index for neonatal transportation (MINT),transport related mortality score (TREMS),transport risk index of physiologic stability (TRIPS) for predicting mortality of preterm infants.Result (1) A total of 527 cases of ELBW/VLBW infants were included in our study.There were no deaths during transport.There were 10.2％ (54/527) died within and 8.9％ (42/473) died after 7 days of hospitalization.(2) Multivariate Logistic regression analysis showed that scleredema of newborn,secondary transport,gastrointestinal malformations,metabolic acidosis,high TREMS score,and high MINT score were risk factors of mortality within 7 days of admission for ELBW/VLBW infants;necrotizing enterocolitis,intraventricular hemorrhage ≥ three degree,high MINT score and low admission weight were risk factors of mortality after 7 days of admission.(3) The area under the ROC curve for MINT,TREMS,and TRIPS score were 0.672,0.655 and 0.665,respectively.The cut-off values for MINT score (cut-off 8,sensitivity 0.444,specificity 0.829),for TREMS score (cut-off 2,sensitivity 0.500,specificity 0.757,for TRIPS score (cut-off 20,sensitivity 0.444,specificity O.829) were selected to predict mortality within 7 days of admission.Conclusion (1) Secondary transport is the transport-related risk factor of mortality within 7 days of admission for ELBW/VLBW infants.(2) High MINT score is the risk factor of mortality within and after 7 days of admission.(3) If MINT ≥ 8,TREMS ≥2,or TRIPS ≥20,it might significantly increase the risk of mortality of ELBW/ VLBW infants within 7 days of admission after transport.

Effects of heated gel mattress for prevention of hypothermia in preterm infants during intra-hospital transport: a Meta-analysis and trial sequential analysis / 中国实用护理杂志

Objective To evaluate the efficacy and safety of heated gel mattress(HGM) for prevention of heat loss on preterm infants with hypothermia during the transport systematically and objectively. Methods Systematic searches on PubMed, EMBASE, Cochrane Library, Web of Science CBM,CNKI,Wanfang and VIP were performed for randomized controlled trials or quasi-randomized control trials which explored the effects of HGM on prevention of hypothermia in premature infants relative to conventional alternatives. Studies were screened according to inclusion and exclusion criteria,extracting data and assessing quality. Then, Meta-analysis and trial sequential analysis were performed by using RevMan 5.3 and TSA v0.9 software developed at the Copenhagen Clinical Trials Center in Denmark, independently. Results This systematic review included 10 studies which comprised 7 randomized controlled trials and 3 quasi-randomized control trials, encompassing 773 patients. The results of Meta-analysis showed that in HGM group admission temperature on neonatal intensive care unit (standardized mean difference was 0.63, 95% confidence interval was 0.40-0.87, P=0.00), incidence of hypothermia (relative risk was 0.73, 95% confidence interval was 0.57-0.93, P=0.01) and hyperthermia (relative risk was 1.82, 95% confidence interval was 1.31-2.54, P=0.00) compared with the control group had significantly statistical difference;however, there was no significant difference in admission temperature on EM or TWM group, mortality, sepsis, retinopathy of prematurity, intraventricular hemorrhage III/IV between two groups. TSA confirmed that the pooled results of admission temperature on NICU and hyperthermia were stable and reliable; but the combination of low-temperature incidence and mortality indicators suggested that the sample size was insufficient. Conclusions HGM is an effective rewarming intervention that can improve body temperature of hypothermic preterm infants during transport, reduce the incidence of hypothermia but not decrease the incidence of morbidity and complications. However, it is recommended that clinical monitoring of body temperature should be performed dynamically to decrease the potential risk of high fever and complications. In addition, due to the limitation of quantity and quality of included studies, its cost-effectiveness and far-reaching influence on long-term follow-up outcomes need further evaluation through clinical multicenter, large sample, high-quality research.

Conclusion Cluster management strategy can improve the safety of ICU patients in hospital transport, and suggest extensive clinical promotion.

Factors related to use of emergency medical services in patients with acute stroke / 中华急诊医学杂志

Objective To examine the availability of emergency medical services(EMS) for patients with acute stroke and to investigate influential factors affecting the preference of patients'to EMS.Methods Consecutive information of patients with acute stroke who presented to the emergency department of Zhongnan Hospital of Wuhan University from June 1, 2014 to December 31, 2015 were analyzed.Gender, age of patients, transport modality, risk factors in cerebrovascular diseases, initial symptoms, stroke types, onset and admission time were included to make analysis in retrospective study.The participants were divided into two groups based on the preference of patients, namely EMS group and self-transport group.Wilcoxon rank sum test or Chi-squared test was used to statistical analysis as appropriate.A multiple binary logistic regression was used to determine the relationship between various patient-related factors with probability whether patients chose EMS or not.Results Among the 240 patients, only 29.2%of them asked for the EMS at the onset of symptoms (EMS group, n=70), and the rest patients called for other services(self-transport group, n=170).Logistic regression analysis revealed that the patients with the symptom of altered consciousness or convulsion (95%CI:0.107-0.403,OR=0.208,P<0.01) were more likely to use EMS.The time consumed from onset to visit of patients with acute stroke to emergency physician was significantly shorter in EMS group (M, 60 min vs.180 min,P<0.01).Conclusion The symptom of altered consciousness or convulsion was the independent factor to determine whether patients with acute stroke preferred EMS or not.

Risk factors of oxygen saturation decrease during intrahospital transportation of intensive care unit patients in emergency department / 中华护理杂志

Objective To explore risk factors of oxygen saturation (SpO2) decrease during intrahospital transporta-tion (IHT) of intensive care unit (ICU) patients in emergency department,and provide theoretical basis for prevent-ing oxygen saturation decrease during intrahospital transportation. Methods A cross-sectional study design was adopted,from April to May,2017,we investigated 182 ICU patients who required IHT in an emergency department in a tertiary hospital in Shanxi Province by using self-designed Evaluation Form of Intrahospital Transportation for ICU Patients in Emergency Room. We divided patients into two groups based on whether their SpO2 decreased or not. Risk factors of SpO2 decrease were identified by univariate and multivariate Logistic regression analysis. Results Among 182 patients,117 had SpO2 decrease,and the rate of SpO2 decrease was 64.3%. Patient's age,MEWS score, disease type,escort personnel,and oxygen supply device were risk factors of SpO2 decrease. Conclusion SpO2 de-crease is the result of combination of multiple risk factors during IHT. We ought to enhance training of escort person-nel,assess patient's condition and SpO2 level accurately and make plan before transportation,choose qualified oxygen supply device to ensure patients can have effective oxygen supply during IHT,which prevent SpO2 decrease during IHT.

Objective To compare inter-hospital transport and clinical outcome in severe acute respiratory distress syndrome(ARDS)patients whom were transported either on extracorporeal membrane oxygenation(ECMO) or on conventional ventilation,and to investigate the optimal means of inter-hospital transport. Methods Eleven patients with severe ARDS who were invalid under conventional ventilation and were transported from other hospitals to Tianjin Third Central Hospital from November 2009 to January 2014 were analyzed. Five patients were transported on ECMO(observation group)and 6 on conventional ventilation(control group). The clinical characteristics,outcomes, transportation,vital signs before and after transportation,respiratory parameters,and Murray score between two groups were compared. Results Patients in observation group were significantly older than those in control group〔years:73(46,77)vs. 34(23,46),Z=-2.293,P=0.022〕. There was no significant difference between observation group and control group in acute pathologic and chronic health evaluationⅡ(APACHEⅡ)score,Murray score,oxygenation index(PaO2/FiO2)before transportation,transit time,and transit distance〔APACHEⅡscore:36(33,39)vs. 27(23,35),Z=-1.830,P=0.067;Murray score:3.5±0.3 vs. 3.4±0.2,t=0.667,P=0.524;PaO2/FiO2(mmHg, 1 mmHg=0.133 kPa):61±14 vs. 63±14,t=-0.249,P=0.809;transit time(minutes):24(18,74)vs. 79(41, 86),Z=-1.654,P=0.098;transit distance(km):12.9(8.3,71.8)vs. 72.4(39.5,86.8),Z=-1.651,P=0.099〕. There was no significant difference between two groups in vital signs and respiratory parameters before transportation. When arrived in ECMO centre,heart rate,respiratory rate,fractional inspired oxygen,inspiratory pressure and Murray score in observation group were significantly lower than those in control group〔heart rate(beat/min):102±16 vs. 136±8, t=-4.374, P=0.002;respiratory rate(beat/min):23±3 vs. 37±2,t=-7.967,P=0.000;fractional inspired oxygen:0.40±0.05 vs. 0.96±0.09,t=-12.152,P=0.000;inspiratory pressure(cmH2O, 1 cmH2O=0.098 kPa):21±1 vs. 34±4,t=-6.887,P=0.000;Murray score:2.7±0.2 vs. 3.8±0.2,t=-8.573, P=0.000〕,but PaO2/FiO2 was higher than that of control group(mmHg:278±65 vs. 41±5 ,t=8.075,P=0.001). Four patients were survived in observation group,and one died from the shortage of oxygen induced lung injury deterioration during transportation. Three patients died in control group,which was directly associated with lung injury deterioration. Conclusion For patients with severe ARDS who need the support of ECMO,ECMO-assisted transfer is safer than conventional ventilation,but transfer should be implemented by experienced team.
