Abstract Background Secondary lung injury is the most common non-neurological complication after traumatic brain injury (TBI). Lung-protective ventilation (LPV) has been proven to improve perioperative oxygenation and lung compliance in some critical patients. This study aimed to investigate whether intraoperative LPV could improve respiratory function and prevent postoperative complications in emergency TBI patients. Methods Ninety TBI patients were randomly allocated to three groups (1:1:1): Group A, conventional mechanical ventilation [tidal volume (VT) 10 mL/kg only]; Group B, small VT (8 mL/kg) + positive end-expiratory pressure (PEEP) (5 cmH2O); and Group C, small VT (8 mL/kg) + PEEP (5 cmH2O) + recruitment maneuvers (RMs). The primary outcome was the incidence of total postoperative pulmonary complications; Secondary outcomes were intraoperative respiratory mechanics parameters and serum levels of brain injury markers, and the incidence of each postoperative pulmonary and neurological complication. Results Seventy-nine patients completed the final analysis. The intraoperative PaO2 and dynamic pulmonary compliance of Groups B and C were higher than those of Group A (P = 0.028; P = 0.005), while their airway peak pressure and plateau pressure were lower than those of group A (P = 0.004; P = 0.005). Compared to Group A, Groups B and C had decreased 30-day postoperative incidences of total pulmonary complications, hypoxemia, pulmonary infection, and atelectasis (84.0 % vs. 57.1 % vs. 53.8 %, P = 0.047; 52.0 % vs. 14.3 % vs. 19.2 %, P = 0.005; 84.0 % vs. 50.0 % vs. 42.3 %, P = 0.006; 24.0 % vs. 3.6 % vs. 0.0 %, P = 0.004). Moreover, intraoperative hypotension was more frequent in Group C than in Groups A and B (P = 0.007). At the end of surgery, the serum levels of glial fibrillary acidic protein and ubiquitin carboxyl-terminal hydrolase isozyme L1 in Group B were lower than those in Groups A and C (P = 0.002; P < 0.001). The postoperative incidences of neurological complications among the three groups were comparable. Conclusions Continuous intraoperative administration of small VT + PEEP is beneficial to TBI patients. Additional RMs can be performed with caution to prevent disturbances in the stability of cerebral hemodynamics.

Some studies have reported that a core vestibular projection (CVP) injury is associated with dizziness following a brain injury using diffusion tensor tractography (DTT). On the other hand, there has been no DTT study on dizziness caused by a CVP injury in patients with mild traumatic brain injury (TBI). In this study, DTT was used to examine the relationship between dizziness and CVP injury in patients with mild TBI. Forty-three patients with mild TBI and twenty-nine normal subjects were recruited. The patients were classified into two groups based on the dizziness score: group A, patients with a dizziness score less than 2 on the sub-item score for dizziness in the Rivermead Post-concussion Symptoms Questionnaire; group B, patients with a dizziness score above 2. The tract volume (TV) in group B was significantly lower than group A and the control group (p < 0.05). By contrast, the TV in group A was similar to the control group (p > 0.05). Regarding the correlation, the dizziness score of all patients showed a strong negative correlation with the TV of the CVP (r = −0.711, p < 0.05). DTT revealed the CVP injury in patients with dizziness after mild TBI. In addition, the severity of dizziness of these patients was closely related to the injury severity of the CVP.

Abstract Introduction: A lot of clinical studies have shown that during prolonged surgery protective ventilation strategy, including low tidal volume, PEEP and recruitment maneuvers (RM) can reduce the rate of postoperative pulmonary complications, which are the second most common cause for postoperative mortality. Therefore, it is important to investigate clinical methods for preventing them. The strategy of protective ventilation is easy and safe for the patients and inexpensive for application during prolonged surgery. Aims: The objective of this trial was to study whether application of PEEP in patients during prolonged gynecological surgery could decrease the postoperative complications. Material and Methods: We compared the rates of postoperative complications in patients after prolonged open gynecological surgery, who were divided into 2 groups – group A, which was the control group on non-protective ventilation (35 patients) and group B on protective ventilation (35 patients). The patients in the control group were ventilated with tidal volume (VT) of 8-10 ml/kg without PEEP and RM; the patients in group B were ventilated with VT = 6-8 ml/kg according to their Predicted Body Weight, with a PEEP of 6 cm H2O and RM, which consisted of applying continuous positive airway pressure of 30 cm H2O for 30 seconds. RM was performed after intubation, after every disconnection from ventilator and before extubation. The study was successfully performed without a need for a change in the type of ventilation strategy because of hypoxia or hemodynamic instability. Statistical nonparametric test (e.g. chi-square) was applied. Results: Total rate of all postoperative complications observed in both groups was 27,1%. We found a significant relationship between application of PEEP and lower rates of postoperative pulmonary complications in group A (39,4%) compared to group B (12,1%), lower rate of respiratory failure (33,3% in group A vs. 9,1% in group B -) and atelectasis (21,2% in group A vs. 0% in group B). Conclusion: The protective ventilation strategy (low VT, PEEP and RM) in patients during prolonged gynecological surgery can reduce the rate of postoperative pulmonary complications such as respiratory failure and atelectasis.

Abstract Background: Postoperative pulmonary complications (PPCs) is the most common perioperative complication following surgical site infection (SSI), which prolongs the hospital stay and increases health care cost. Lung-protective ventilation strategy is considered better practice in abdominal surgery to prevent PPCs. However, the role of inspiratory oxygen fraction (FiO₂) in the strategy remains disputable. Previous trials have focused on reducing SSI by increasing inhaled oxygen concentration but higher FiO₂ (80%) was found to be associated with a greater incidence of atelectasis and mortality in recent researches. The trial aims at evaluating the effect of different FiO₂ added to lung-protective ventilation strategy on the incidence of PPCs during general anesthesia for abdominal surgery. Methods: PROtective Ventilation with a low versus high Inspiratory Oxygen fraction trial（PROVIO）is a single-center, prospective, randomized, controlled trial planning to recruit 252 patients undergoing abdominal surgery lasting for at least 2 hours. The patients will be randomly assigned to (1) a low FiO₂ (30% FiO₂) group and (2) a high FiO₂ (80% FiO₂) group in lung-protective ventilation strategy. The primary outcome of the study is the occurrence of PPCs within the postoperative 7 days. Secondary outcomes include the severity grade of PPCs, the occurrence of postoperative extrapulmonary complications and all-cause mortality within the postoperative 7 and 30 days. Discussion: PROVIO trial assesses the effect of low versus high FiO₂ added to lung-protective ventilation strategy on PPCs for abdominal surgery patients and the results will provide practical approaches to intraoperative oxygen management.

Abstract Airway humidification is an essential treatment for severe traumatic brain injury (STBI) patients after tracheotomy. To date, there was no relevant quantitative study evaluating these humidification ways and providing the appropriate method for the long-term nursing of these patients. In this study, 150 patients whom received tracheotomy treatment in our hospital from January 2016 to November 2018 were recruited into this study. Subjects were divided into three groups according to the humidification way that they received. The groups were oxygen spraying group (group A), Heat and moisture exchanger (HME) group (group B) and the heating and humidification group (group C). Phlegm viscosity, humidification effect, phlegm formation rate, daily sputum inhalation times, airway spasm, secondary lung infection, daily nursing times, nurses' internal satisfaction were evaluated. The C method is superior to both A and B methods in most aspects. A method trends to happening with insufficient or excessive humidification. Phlegm scab formation is significantly less in group C. The B and C methods had equal humidification effects and need similar daily sputum inhalation nursing. Airway spasm was frequent happened in group A than that in groups B and C. Secondary infection happened in all groups, the number of infected patients showed a decreasing trend and the infection degree showed no difference in the first 7 days between group C and group A. And the severity but not the infection ratio significantly decreased in Group C on the 30 th day. Method A significantly reduced nursing workload, but gained the worst humidification effects. Collectively, C method is more suitable for the airway nursing of patients with severe traumatic brain injury.

OBJECTIVE: To evaluate the efficiency of selective hypothermia in the treatment of the traumatic brain injury in rats. METHOD: After the trauma produced for the model of cortical impact, a small craniectomy in the right frontoparietal region was carried through; after the procedure the animals had been divided in two groups of 15 each. Group A, without treatment with hypothermia (control group) and group B, treated with selective hypothermia for a period to 5 to 6 hours. After this time all the animals were sacrificed, their brains had been removed and histopathological analysis was carried through. RESULTS: Comparison between both groups was done using the counting of neurons injured for field. Counting in the control group n=15 had an average of 70.80 neurons injured for field against an average of 21.33 neurons injured for field in group B (submitted to the treatment with hypothermia), with n=15 also. The difference was statiscally significant. CONCLUSION: Based in the quantification of the neurons injured for field, the effectiveness of the treatment with selective hypothermia was demonstrated.

Background: Severe traumatic brain injury can be a serious condition. Objective: The purpose of the present study was to see the decompressive craniectomy (DC) of severe traumatic brain injury. Methodology: This clinical trial was conducted in the Department of Neurosurgery at Dhaka Medical College Hospital, Dhaka, Bangladesh from January 2012 to December 2013 for a period of two (02) years. Patients with the age of 18 years and above, GCS of the patients 8 to 4, severe traumatic brain injury (TBI) with multiple hemorrhagic contusions and midline shift, on CT scan and severe TBI with gradual neurological deterioration were included for this study. Total 60 patients were included. Result: A total of 60 patients were included in this study. Almost two third 18 (60.0%) patients had favorable outcome (GOS 4 and 5) in group A and exactly two third 20(66.7%) patients had Unfavorable outcome (GOS 1,2 and 3) in group B (p<0.05). In this study 8 patient died among which 5 had GCS 4 and 3 had GCS 5. One patient with GCS 5 became persistent vegetative. Eight patient with good recovery had GCS 8, 7 and 6. Death occurred at mean GCS 9±2.mm of midline shift followed by 8± mm in persistent vegetative, 5.67±2.08 mm in severe disability, 4.5±2.88 mm in moderate disability and 3.38±1.06 mm in good recovery. Conclusion: Group A had better clinical outcome than group B. So based on statistical analysis it can be concluded that DC is preferable to conservative management in case of severe TBI.
