Effect of Early Controlled Hypotension on Patients with Traumatic Brain Injury

Objective:To investigate the clinical effect of early controlled hypotensive therapy in patients with traumatic braininjury(TBI).Methods:68 patients with acute 1Bl in our hospital were selected for this investigation.They were evenly divided into a control group and an observation group according to the difference of blood pressure and basic level,whose lesion area after treatment,postoperative intracranial pressure after 2 d and 7d,and Gcs score of prognostic quality before and after treatment were made comparison.Results:The post-treatment lesion area of the observation group was lower than that in the control group(P<0.05);the postoperative intracranial pressure after 2d and 7d of the control group was better than the observation group(P<0.05),and the same with GCS score,which has statistical sigmificance(P< 0.05).Conclusion:Early controlled hypotensive therapy has a significant clinical effect on patients with brain trauuma,it can reduce the lesion area after treatment and postoperative intracranial pressure as well.

Haemodynamic management in brain death donors:Influence of aetiology of brain death

BACKGROUND In brain death donors(BDDs),donor management is the key in the complex donation process.Donor management goals,which are standards of care or clinical parameters,have been considered an acceptable barometer of successful donor management.AIM To test the hypothesis that aetiology of brain death could influence haemodynamic management in BDDs.METHODS Haemodynamic data(blood pressure,heart rate,central venous pressure,lactate,urine output,and vasoactive drugs)of BDDs were recorded on intensive care unit(ICU)admission and during the 6-h observation period(Time 1 at the beginning;Time 2 at the end).RESULTS The study population was divided into three groups according to the aetiology of brain death:Stroke(n=71),traumatic brain injury(n=48),and postanoxic encephalopathy(n=19).On ICU admission,BDDs with postanoxic encephalopathy showed the lowest values of systolic and diastolic blood pressure associated with higher values of heart rate and lactate and a higher need of norepinephrine and other vasoactive drugs.At the beginning of the 6-h period(Time 1),BDDs with postanoxic encephalopathy showed higher values of heart rate,lactate,and central venous pressure together with a higher need of other vasoactive drugs.CONCLUSION According to our data,haemodynamic management of BDDs is affected by the aetiology of brain death.BDDs with postanoxic encephalopathy have higher requirements for norepinephrine and other vasoactive drugs.

Pain management in acute musculoskeletal injury: Effect of opioid vs nonopioid medications

BACKGROUND The use of opioids for pain is linked to an increased risk of developing opioid use disorder,and has resulted in the emergence of the opioid crisis over the last few years.AIM The systematic review question is“How does the use of opioid medications in pain management,compared with non-opioid medications,affect pain intensity over the short,intermediate,and long-term in adults with acute traumatic pain?”.METHODS The protocol was prospectively registered on the International Prospective Re-gister of Systematic Reviews:CRD42021279639.Medline and Google Scholar were electronically searched for controlled peer-reviewed studies published in full,with the PICO framework:P:Adult patients with traumatic injuries,I:Opioid medications,C:Non-opioid medi-cations,O:A minimum clinically important difference(MCID)in pain.RESULTS After full-text screening,we included 14 studies in the qualitative synthesis.Of these 14 studies,12 were rando-mized clinical trials(RCTs)and 2 were pseudo-RCTs with a total of 2347 patients enrolled.There was heteroge-neity in both medication utilized and outcome in these studies;only two studies were homogeneous regarding the type of study conducted,the opioid used,its comparator,and the outcome explored.The MCID was evaluated in 8 studies,while in 6 studies,any measured pain reduction was considered as an outcome.In 11 cases,the setting of care was the Emergency Department;in 2 cases,care occurred out-of-hospital;and in one case,the setting was not well-specified.The included studies were found to have a low-moderate risk of bias.CONCLUSION Non-opioids can be considered an alternative to opioids for short-term pain management of acute musculoskeletal injury.Intravenous ketamine may cause more adverse events than other routes of administration.
