Abstract

OBJECTIVE This study aimed to observe the application effect of emergency treatment mode of damage-control orthopedics (DCO) in pelvic fracture complicated with multiple fractures. METHODS Ninety-four patients with pelvic fracture complicated with multiple fractures in our hospital were recruited and divided into two groups according to the random number table method, with 47 cases in each group. Patients in the control group received traditional methods for emergency treatment (early complete treatment), and patients in the research group received DCO for emergency treatment (treatment performed in stages according to patient's physiological tolerance, with simplified initial surgery, followed by ICU resuscitation, and finally definitive surgery). The two groups were compared in terms of mortality, the incidence of acidosis and hypothermia three days after the first surgery, surgery-related indexes (time of the first surgery, blood transfusion volume, intraoperative blood loss, recovery time of temperature, and length of hospital stay), coagulation function indexes (activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin time (PT) and fibrinogen (FIB)), postoperative reduction of fracture, complication rate, and quality of life. RESULTS The incidences of acidosis, hypothermia, and mortality three days after the first surgery in the research group were lower than those in the control group (P<0.05). Compared with the control group, the research group experienced shorter time of the first surgery, less intraoperative blood transfusion volume, less intraoperative blood loss, shorter recovery time of body temperature, and shorter length of hospital stay (P<0.05). Seven days after surgery, PT, TT and APTT decreased and FIB increased in both groups (P<0.05), PT, TT and APTT in the research group were lower than those in the control group (P<0.05), while FIB was higher (P<0.05). The good rate of reduction in the research group was higher than that in the control group (P=0.025). The incidence of complications in the research group was lower than that in the control group (P=0.049). Six months after surgery, the scores of physiological function (PF), body pain (BP), role physical (RP), emotional function (EF), social function (SF), vitality, and general health (GH) of the research group were higher than those of the control group (P<0.05), but there was no significant difference in mental health (MH) between the two groups (P>0.05). CONCLUSION The emergency treatment mode of DCO is effective in pelvic fracture complicated with multiple fractures, which can effectively improve postoperative reduction of patients, improve the coagulation function, reduce complications, and improve the quality of life.

Abstract

BACKGROUND Early out-of-bed mobilization may improve acute post-intracerebral hemorrhage (ICH) outcomes, but hemodynamic instability may be a concern. Some recent studies have showed that an increase in mean systolic blood pressure (SBP) and high blood pressure variability (BPV), high standard deviation of SBP, may lead to negative ICH outcomes. Therefore, we investigated the impact of an early mobilization (EM) protocol on mean SBP and BPV during the acute phase. METHODS The study was an assessor-blinded, randomized controlled non-inferiority study. The participants were in An Early Mobilization for Acute Cerebral Hemorrhage trial and were randomly assigned to undergo EM or a standard early rehabilitation (SER) protocol within 24 to 72 hour after ICH onset at the stroke center. The EM and SER groups each had 30 patients. 24-measurement SBP were recorded on days 2 and 3 after onset, and SBP were recorded three times daily and during rehabilitation on days 4 through 7. The two groups' mean SBP and BPV under three different time frames (days 2 and 3 during the acute phase, and days 4 through 7 during the late acute phase) were calculated and compared. RESULTS At baseline, the two groups' results were similar, with the exception being that the mean time to first out-of-bed mobilization after symptom onset was 51.60 hours (SD 14.15) and 135.02 hours (SD 33.05) for the EM group and SER group, respectively (P < .001). There were no significant differences in mean SBP and BPV during the acute and late acute phase between the two groups for the three analyses (days 2, 3, and 4 through 7) (P > .05). CONCLUSIONS It is safe to implement the EM protocol within 24 to 72 hour of onset for mild-moderate ICH patients during the acute phase.

Abstract

INTRODUCTION Hip fractures in orthopedic trauma cases are increasing. Majority of such patients undergoing surgery require blood transfusion of one or more units. Intravenous (I. V.) Tranexamic acid (TXA) may decrease loss of blood, decrease need of blood transfusion, and improve postoperative hemoglobin (Hb) along with lesser adverse effects. Risk of thromboembolic phenomena remains a concern. A study was done to analyze the role of I. V. TXA in hip fracture surgeries in trauma cases. MATERIALS AND METHODS Sixty patients were included in the study; in two groups (37 males and 23 females), Group A in which two doses of I. V. TXA 15 mg/kg were given and Group B in which two doses of I. V. placebo were given. RESULTS Total number of randomized hip arthroplasty cases was 22 (11 in Group A and 11 in Group B) whereas randomized osteosynthesis cases were 38 (19 in Group A and 19 in Group B). Mean preoperative Hb value in Group A was 10.8 gm% and in Group B was 10.7 gm% (P > 0.005. Mean postoperative Hb value in Group A was Hb 9.8 gm% and in Group B 9.5 gm% (difference of 3.061%). Mean duration of surgery in Group A was 64.2 min and in Group B was 66.3 min. Mean total blood loss (intraoperative and postoperative) in Group A was 384.6 ml and in Group B was 448.7 ml (14.29% less in Group A). A total of 14 patients in Group A (17 red blood cells [RBCs] units) and 17 patients (21 RBC units) in Group B required RBC transfusion. No major vascular event, severe bacterial infections, symptomatic deep vein thrombosis, pulmonary embolism, limb ischemia, acute coronary syndrome, or immediate postoperative mortality was noted in either group. CONCLUSION I. V. TXA has the potential to decrease risk of blood transfusion, decrease total blood loss, and to maintain a higher postoperative Hb value with no significant adverse reactions. As the number of cases of hip fractures continues to increase along with increase in age, so the use of TXA in such cases may improve clinical outcomes, lessen number of inpatient days and hence decrease overall cost.

Abstract

INTRODUCTION Post-operative blood loss in lower limb trauma fractures increases morbidity. Very few studies have evaluated the efficacy of Tranexamic Acid (TXA) in reducing blood loss and the consequent requirement of blood transfusion in the Indian population. METHODS This was a randomized controlled study of 100 patients with lower limb trauma. Fifty patients were given 1 g of TXA before surgery, and 50 patients were not given TXA. The requirement of blood transfusion, fall in Hb, the number of days admitted in the hospital after surgery were recorded, and evidence of deep vein thrombosis (DVT) was monitored. RESULTS Baseline demographics between the groups were comparable. The required blood transfusion and fall in Hb in patients receiving intra-operative TXA were significantly lower than those not given TXA (p < 0.0001). There was no significant difference in the length of hospital stay between the two groups (p = 0.6). There was no significant difference in the incidence of DVT in both groups. DISCUSSION TXA helps reduce the morbidity of trauma patients by reducing the requirement for blood transfusion. Its use is safe in lower limb trauma surgery and lowers the cost of therapy to the patient.

Abstract

BACKGROUND The major causes of death of combat casualties in austere environments are related to hemorrhage and occur early after injury. The implementation of a walking blood bank may overcome the logistical issues raised using blood component therapy. Nonetheless, it is important to ensure that this buddy transfusion is not going to compromise the mission success by altering the donor's performance. The results available so far cannot rule out this issue with certainty. Therefore, this study aimed at investigating the immediate effect of a 450-ml blood donation on the performances of elite soldiers in laboratory and field environments. STUDY DESIGN AND METHODS This double-blind, randomized controlled study included two experiments. For both experiments, subjects were randomly assigned either to a control group (n(1) = n(2) = 7) or to a 450-ml-blood-bag donation group (n(1) = 7 and n(2) = 8). All participants underwent before and after a potential blood donation a multifactorial assessment including adapted physical tasks, hematological variables, vigilance parameters, and subjective assessments. RESULTS No significant results were evidenced in this study. There was no impact of blood donation on the participants' performances in both the hospital and the combat-like environments. CONCLUSION From a donor's point of view, a 450-ml blood donation has no impact on the required abilities of our elite soldiers to fulfill a demanding tactical mission. Thus, the results of this study support the fact that buddy transfusions could be part of the operational clinical armamentarium in austere environments for elite soldiers when no blood components are available.

Abstract

BACKGROUND Tranexamic acid safely reduces mortality in traumatic extracranial bleeding. Intracranial bleeding is common after traumatic brain injury and can cause brain herniation and death. We assessed the effects of tranexamic acid in traumatic brain injury patients. OBJECTIVE To assess the effects of tranexamic acid on death, disability and vascular occlusive events in traumatic brain injury patients. We also assessed cost-effectiveness. DESIGN Randomised trial and economic evaluation. Patients were assigned by selecting a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients, caregivers and those assessing outcomes were masked to allocation. All analyses were by intention to treat. We assessed the cost-effectiveness of tranexamic acid versus no treatment from a UK NHS perspective using the trial results and a Markov model. SETTING 175 hospitals in 29 countries. PARTICIPANTS Adults with traumatic brain injury within 3 hours of injury with a Glasgow Coma Scale score of ≤ 12 or any intracranial bleeding on computerised tomography scan, and no major extracranial bleeding, were eligible. INTERVENTION Tranexamic acid (loading dose 1 g over 10 minutes then infusion of 1 g over 8 hours) or matching placebo. MAIN OUTCOME MEASURES Head injury death in hospital within 28 days of injury in patients treated within 3 hours of injury. Secondary outcomes were early head injury deaths, all-cause and cause-specific mortality, disability, vascular occlusive events, seizures, complications and adverse events. RESULTS Among patients treated within 3 hours of injury (n = 9127), the risk of head injury death was 18.5% in the tranexamic acid group versus 19.8% in the placebo group (855/4613 vs. 892/4514; risk ratio 0.94, 95% confidence interval 0.86 to 1.02). In a prespecified analysis excluding patients with a Glasgow Coma Scale score of 3 or bilateral unreactive pupils at baseline, the results were 12.5% in the tranexamic acid group versus 14.0% in the placebo group (485/3880 vs. 525/3757; risk ratio 0.89, 95% confidence interval 0.80 to 1.00). There was a reduction in the risk of head injury death with tranexamic acid in those with mild to moderate head injury (166/2846 vs. 207/2769; risk ratio 0.78, 95% confidence interval 0.64 to 0.95), but in those with severe head injury (689/1739 vs. 685/1710; risk ratio 0.99, 95% confidence interval 0.91 to 1.07) there was no apparent reduction (p-value for heterogeneity = 0.030). Early treatment was more effective in mild and moderate head injury (p = 0.005), but there was no obvious impact of time to treatment in cases of severe head injury (p = 0.73). The risk of disability, vascular occlusive events and seizures was similar in both groups. Tranexamic acid is highly cost-effective for mild and moderate traumatic brain injury (base case of £4288 per quality-adjusted life-year gained). CONCLUSION Early tranexamic acid treatment reduces head injury deaths. Treatment is cost-effective for patients with mild or moderate traumatic brain injury, or those with both pupils reactive. FUTURE WORK Further trials should examine early tranexamic acid treatment in mild head injury. Research on alternative routes of administration is needed. LIMITATIONS Time to treatment may have been underestimated.

Abstract

BACKGROUND Early lactate-guided resuscitation was endorsed in the guidelines of the Surviving Sepsis Campaign as a key strategy to decrease the mortality of patients admitted to the ICU department with septic shock. However, its effectiveness in elderly Asian patients is uncertain. METHOD We conducted a single-center trial to test the effectiveness of the early lactate-guided resuscitation of older Asian patients at the Second Hospital of Hebei Medical University. Eligible septic shock patients who consented to participation in the study were randomly assigned to receive early lactate-guided treatment or regular treatment as controls. RESULT A total of 82 patients met the hyperlactatemia criteria and participated in the trial. Forty-two patients received early lactate-guided treatment (lactate group) and 40 received regular treatment (control group). The lactate group received more fluids at initial 6 hours (3.3 ± 1.4 vs 2.4 ± 1.7 L, P = 0.01), but similar proportions of patients in both groups required the use of vasopressors and vasodilators. Patients in the lactate group showed significantly reduced ICU needs compared to the control group, which were weaned from mechanical ventilation more quickly (median 7, IQR 4 to 14 vs median 9, IQR 4.3 to 17.8, P = 0.02) and transferred out of the ICU earlier (median 4.5, IQR 2.8 to 7.3 vs median 6, IQR 3.2 to 8, P = 0.01). However, the hospital mortality (35.7% vs 42.5%, P = 0.35) and ICU mortality (31.0% vs 37.5%, P = 0.38) for both groups were not reduced. CONCLUSION For critically ill patients (elderly Asian patients) admitted to the ICU department with hyperlactatemia, early lactate-guided treatment reduced ICU needs but did not reduce mortality.

Abstract

Current evidences in resuscitation of adult sepsis have pointed to the importance of types of crystalloid fluid-related complications on resuscitation outcomes, but evidences are lacking in pediatric populations. In this study, the authors aimed to compare outcomes of pediatric sepsis resuscitation with different types of crystalloid. They randomly assigned pediatric sepsis patients requiring fluid bolus into three groups to receive either normal saline solution (NSS), Ringer lactate solution (RLS), or Sterofundin as fluid bolus therapy. Forty-two patients were included in the study. Median age was 29 mo and, weight 13 kg. After fluid bolus, the complications were not different among groups. However, in the RLS group, the patients who received large dose of the fluid showed significant reduction in urinary neutrophil gelatinase-associated lipocalin (uNGAL) level. It is concluded that fluid bolus therapy with different types of crystalloid solution did not result in different outcomes but large dose of RLS was associated with greater reduction of uNGAL level, compared to other fluids.Trial Registration: Thai Clinical Trial Registry (TCTR) identification number TCTR20170605001 (retrospectively registered on 1st June 2017). https://www.clinicaltrials.in.th/index.php?tp=regtrials&menu=trialsearch&smenu=fulltext&task20=search&task2=view1&id=2576.

Abstract

The present study aimed to explore the efficacy of intravenous immunoglobulin (IVIG) injection in neonates with acute lung injury (ALI) and assess its effects on serum inflammatory cytokine levels. The research subjects were 140 neonates with ALI who were evenly distributed into a control group (COG) and a study group (STG). The COG patients were treated routinely, whereas patients in the STG were administered IVIG in addition to the standard treatment received by the COG. The arterial partial pressure of oxygen (PaO(2)), PaO(2)/fraction of inspired oxygen (FIO(2)), mechanical ventilation time and hospitalization time were compared between the two groups. ELISA was used to determine the levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the patients before treatment and at 12, 24 and 36 h after treatment. The Kaplan-Meier method was used to analyze the survival of the patients, including their survival for 30 days after treatment. The patients were divided into high and low cytokine expression groups based on their mean expression levels of serum IL-6 and TNF-α before treatment. After treatment, PaO(2) and PaO(2)/FiO2 were significantly higher and mechanical ventilation and hospitalization time were reduced in the STG in comparison with the COG (all P<0.001). At 12, 24 and 36 h after treatment, serum IL-6 and TNF-α levels in the STG were lower than those in the COG (both P<0.05). The 30-day survival rate after treatment was not significantly different between the two groups (P>0.05). The 30-day survival rate in the high IL-6 and high TNF-α expression COG was lower than that in the low IL-6 and low TNF-α expression COG (both P<0.05). The results of the present study indicate that IVIG may improve pulmonary gas exchange, shorten the course of disease and reduce the inflammatory response in neonates with ALI.

Abstract

Conventionally the packed red blood cell (PRBC) transfusion volume given to neonates is 10 ml/kg to 20 ml/kg. The weight-based formulae underestimate the volume of PRBC required to achieve a target hematocrit (Hct) in preterm neonates. The study was done to compare the rise in Hct after transfusing PRBC volume calculated either based on body weight or using formula considering Hct of blood bag and Hct of preterm neonates. This prospective study included a total of 68 preterm neonates requiring transfusion for the first time having ≤ 34 weeks of gestational age. Neonates were randomized using block randomization, to receive 15 ml/kg of PRBC transfusion (group A) or transfusion based on the formula (group B). The primary outcome of interest was post-transfusion rise in hematocrit. The secondary outcome was the effect of transfusion on neonatal morbidities in terms of retinopathy of prematurity, bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, and death. Baseline variables (birth weight, gestation age, APGAR score and score of neonatal acute physiology) pre-transfusion hemodynamics and hematocrit of the bag were comparable in both groups. The mean volume of PRBC in group A was 18.8 ± 4.9 ml, whereas in group B it was 29.6 ± 7.3 ml, p = 0.0001. Group B transfusions had a statistically significant change in 24 h post-transfusion hematocrit. Secondary outcomes were comparable in two groups. Post transfusion rise in Hct of the patient in group B was significant as compared to group A. The study needed huge sample size to establish a difference in the number of re-transfusions required across two groups. The trial was registered under the clinical trial registry of India (CTRI/2018/01/011,063).
