To promote the clinical treatment technical training and popularization of traumatic shock and cardiac arrest, Health Emergency Committee of Chinese Research Hospital Association, Cardiopulmonary Resuscitation Specialized Committee of Chinese Research Hospital Association, Cardiopulmonary Resuscitation Specialized Committee of Henan Hospital Association jointly established "Chinese expert consensus on the clinical application of innovative first-aid resuscitation technology for traumatic shock in 2019". This consensus has solved the problem of volume resuscitated gel mix and ratio in the emergency situation of pre-hospital transfusion and blood products unable to be used in traumatic shock. Hypertonic gel compound liquid can treat traumatic shock with small dosage and good effect of stabilizing blood pressure, which can replace whole blood and other blood products, improve the safety of transport to hospital, and provide an opportunity for life-saving surgery. At the same time, abdominal lifting and compression cardiopulmonary resuscitation (CPR) has solved the difficulty of treating patients with post-traumatic cardiac arrest who cannot perform traditional chest compressive CPR, and greatly improved the success rate of pre-hospital treatment for patients with traumatic shock. In view of the actual demand of emergency medical treatment in China and the contraband of chest CPR for chest trauma, the combination of "administration, production, study, research and application" was adopted, and the abdominal lifting and compression CPR was successfully developed and popularized. This expert consensus summarized the scientific evidence on traumatic shock and traumatic cardiac arrest published at home and abroad so far, and put forward the expert consensus on the clinical application of innovative first-aid resuscitation technology for traumatic shock based on Chinese national conditions. This consensus incorporated the wisdom and philosophy of Chinese and foreign scholars in the training of traumatic shock and CPR, and would certainly make the training of traumatic shock and cardiac arrest in China entering a new stage with strong pertinence, quick onset, few side effects and high treatment rate.

With the increasing incidence of blast injury, the research on its mechanisms and protective measures draws more and more attention. Blast injury has many characteristics different from general war injuries or trauma. For example, soldiers often have various degrees of visceral injury without significant surface damage, combined injuries and arterial air embolism. Researchers in China began to investigate blast injury later than the United States and Sweden, but the development is so fast that lots of achievements have been gained, including the development of biological shock tube, the mechanisms and characteristics of blast injury in various organs, as well as protective measures under special environments. This article reviews the past and current situation of blast injury research in China.

To retrospect the development of fluid resuscitation for burn shock and to look to the future. The main achievements in burn care in the past fifty years and existing problems are summarized, and the appropriate regime of fluid resuscitation for burn shock is suggested. Numerous achievements in burn care have been made, including the estimation of burn area, fluid replenishment formula, delayed resuscitation, fluid resuscitation for burn shock complicated by inhalation injury, covert compensatory shock and research on mechanism of burn shock etc. We had established and improved fluid resuscitation formula, and we had made clear how to properly resuscitate burn shock. However how to tide over the patient form burn shock smoothly had not yet reached a consensus. Effective treatment to alleviate hypoxic injuries as a result of severe shock had not been properly defined. Although significant achievements in fluid resuscitation for burn shock have been made, there is still a long way to go to attain a perfect regime. Therefore it is still utterly necessary to carry on in-depth research on this problem both in the laboratory and bedside.

It is well known that shock is one of the main complications occurring during early stage of severe burn, and presently, ischemic/hypoxic damage of tissues and organs is still hard to be prevented by various fluid resuscitation regimens. Findings in recent years demonstrated that postburn cardiac damage occurs promptly and much earlier than any other organs. Application of measures to ameliorate cardiac damage may improve organ blood flow in liver, kidney, and intestines, and mitigate organ damage concomitant with fluid resuscitation according to Parkland formula. These facts suggest that cardiac damage occurring promptly at early stage of severe burn is one of the important factors leading to ischemia/hypoxia of tissues and organs, therefore,new resuscitation regimen including "volume replacement" plus "dynamic support" may conduct to more effective burn shock resuscitation, and reduce organ complications as a result of either insufficient or over fluid infusion.

OBJECTIVETo investigate the effect of Shengmai injection on the management of "shock heart" after burns.

METHODSTwenty patients with severe burns were enrolled in the study and randomly divided into two groups according to the clinical research method, i.e. treatment group (n= 10, with intravenous infusion of 40 ml Shengmai injection together with 250ml 50 g/L glucose solution for 3 days, 1 time/ per day) and control group(n = 10, with intravenous infusion of 290 ml 50 g/L glucose injection liquid for 3 days, 1 time/per day). Beside the venous line used for routine fluid resuscitation for burn shock, another venous line was set up after hospitalization for the administration of the drug. Blood samples were obtained from the femoral vein in both groups at 12 post-burn hour( PBH) , and on 1, 2, 3, 4 and 5 post burn days (PBD) for the determination of serum contents of creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH) and cardiac troponin I (cTnI). The changes in hepatic and renal function, as well as coagulability were determined before drug infusion and on 1 , 2, 3, 5 and 7 PSDs.

RESULTSThe serum content of CK-MB, LDH and cTnI reached the peak at 12 PBH in both groups[ (52+/-20)U/L, (5.9+/-1.3) micromol x s(-1) L(-1), (0. 274+/-0. 231) microg/L in treatment group and [(9+/-31)U/L, (8.5+/-1l.8) micromol x s(-1) x L(-1) , (0. 584+/-0. 192) microg/L in control group]. All of them decreased with the passage of time, but in the treatment group they decreased more markedly within 2 or 3 PBD compared with those in control group ( P < 0.05).

CONCLUSIONEarly administration of Shengmai intravenously is beneficial to the protection of myocardial cells and in the management of the "shock heart" damage.

OBJECTIVETo explore fluid management and cause of death during shock period in severe burns or burns with inhalation injury.

METHODSOne hundred and twelve patients with severe burns or burn complicated by inhalation injury admitted to our hospital from 1991 to 2000 were analyzed. The fluid management and death conditions during shock period were discussed.

RESULTSThe fluid volume for resuscitation could be described as follows: the total fluid volume was 2.2 ml/(%TBSA.kg) including colloid fluid 0.5 ml/(%TBSA.kg), crystalloid fluid 1 ml/(%TBSA.kg)and water 0.7 ml/(%TBSA.kg) during first 24 hours. The total fluid volume was 1.8 ml/(%TBSA.kg) including colloid fluid 0.4 ml/(%TBSA.kg), crystalloid fluid 0.7 ml/(%TBSA.kg) and water 0.7 ml/(%TBSA.kg) during second 24 hours. There were no difference in fluid management between burns and burns with inhalation injury. Seven patients died due to respiratory failure during shock period.

CONCLUSIONSMany fluid formula can provide guidance for resuscitation and it is very important that early fluid therapy should accord with concrete clinical conditions of patients in order to pass smoothly through shock period. Early fluid management is not different between burns and burns with inhalation injury.

OBJECTIVETo investigate the relationship between blood concentration of lactic acid (LA) and tissue oxygenation in severely burned patients with shock.

METHODSThirty-four severely burned patients admitted during early postburn stage were included in this study and were randomly divided into A (n = 18) and B (n = 16) groups. The patients in A group were resuscitated with modified anti-shock programme by which the patients' urine output was maintained roughly around 100ml per hour, while the patients in B group were treated by our traditional resuscitation formula by which the patients urine was kept at 40 ml per hour. The blood concentration of LA and usual indices (urine output, blood pressure, heart rate, and mental status) were simultaneously monitored before and 1, 8, 16, 24, 48 and 72 hours after resuscitation in patients of both groups.

RESULTS(1) The average blood LA level in patients of A group was (3.2 +/- 0.4) mmol/L within 24 hours of resuscitation, while the monitored indices remained within normal range. Nevertheless the LA level in B group was (7.4 +/- 1.6) mmol/L (P < 0.01, compared with that of A group), and hyperlactacidemia lasted for more than 72 hours while other indices were normal. (2) The mortality in B group was high (31.2%), whilst that in A-group was only 5.5% (P < 0.01). (3) There was negative correlation between blood LA and urine output and positive correlation between blood LA and heart rate.

CONCLUSION(1) Blood LA concentration might be taken as an immediate, sensitive, simple and useful index of tissue oxygenation of the whole body during burn shock stage. (2) It was suggested by our results that fluid resuscitation should be extended to 72 PBHs (postburn hours) with urine output over 100 ml/h, so as to ensure the quality and effects of the resuscitation of burn shock.

OBJECTIVETo explore the dynamic postburn changes in rat hepatic function and the effects of hyperoxic Ringer's solution resuscitation on the function.

METHODSOne hundred and ninety Wistar rats of both sexes with body weight of 250 - 300 g were employed as the model and were divided into 6 groups as A, B, C, D, E and F groups as follows: normal control (A, n = 10), early resuscitation with Ringer's solution (B, n = 40), delayed resuscitation with Ringer's solution (C, n = 30), early resuscitation with hyperoxic Ringer's solution (D, n = 40), delayed hyperoxic Ringer's solution resuscitation (E, n = 30) and burn control (F, n = 40). Blood samples were drawn from the injured rats under anesthesia at 6, 12, 24 and 48 postburn hours (PBHs), and the serum contents of ALT, AST and MDA in these blood samples were determined. Hepatic tissue samples were also harvested at the same time and served histologically.

RESULTSThe plasma ALT level at 6 PBH in all groups was higher than that in A group (P < 0.05). There was significant difference of plasma ALT levels between hyperoxic Ringer's solution treatment group an other treatment groups (P < 0.05). And there was evident difference of plasma ALT levels between hyperoxic Ringer's solution treatment groups and other treatment groups (P < 0.05). The dynamic change in plasma AST was almost similar to that of ALT. The plasma MDA level was increased obviously after injury, especially in F group (highest level). Furthermore, the MDA level in C group was higher than that in B group. The plasma MDA levels in D and E groups were evidently lower than that in all other groups (P < 0.05). It was revealed by histological examination that there were different degrees of degeneration an necrosis of hepatocytes during early postburn stage, but less so in D group.

CONCLUSIONFluid resuscitation during early postburn stage with hyperoxic Ringer's solution could inhibit the production of oxygen free radicals and blunt lipid peroxidation, and it could also enhance the host tolerance to hypoxia and prevent hepatocytes from injury, thus hepatic function was protected.
