Sedation for Rapid Sequence Induction and Intubation of Neurologically Injured Patients

Traumatic brain injury and RSI is rocuronium or succinylcholine preferred?

PURPOSE OF REVIEW

Traumatic brain injury is widespread and has significant morbidity and mortality. Patients with severe traumatic brain injury often necessitate intubation. The paralytic for rapid sequence induction and intubation for the patient with traumatic brain injury has not been standardized.

RECENT FINDINGS

Rapid sequence induction is the standard of care for patients with traumatic brain injury. Historically, succinylcholine has been the agent of choice due to its fast onset and short duration of action, but it has numerous adverse effects such as increased intracranial pressure and hyperkalemia. Rocuronium, when dosed appropriately, provides neuromuscular blockade as quickly and effectively as succinylcholine but was previously avoided due to its prolonged duration of action which precluded neurologic examination. However, with the widespread availability of sugammadex, rocuronium is able to be reversed in a timely manner.

SUMMARY

In patients with traumatic brain injury necessitating intubation, rocuronium appears to be safer than succinylcholine.

The Value of Emergency Nursing Mode in the Treatment of Patients with Traumatic Shock

OBJECTIVE

To study the value of emergency nursing mode in patients with traumatic shock.

METHODS

76 patients with traumatic shock in our hospital from March 2019 to February 2021 were selected and divided into study group and control group according to different rescue modes, 38 cases in each group. The study group adopted emergency nursing mode for rescue, while the control group adopted routine nursing mode for rescue. The rescue intervention, emergency stay and preoperative preparation time, rescue success rate, emergency rescue effect, complications, and satisfaction rate of patients and their families for rescue were compared between the two groups.

RESULTS

The rescue intervention, emergency stay and preoperative preparation time of the study group were significantly shorter than those of the control group, and the difference was statistically significant (P < 0.05). The rescue success rate of the study group was 97.37%, which was significantly higher than 84.21% of the control group, and the difference was statistically significant (P < 0.05). The improvement rate of the study group was significantly higher than that of the control group, the disability rate was significantly lower than that of the control group, the overall emergency rescue effect was better than that of the control group, and the difference was statistically significant (P < 0.05). The incidence of complications in the study group was 2.63%, which was significantly lower than 23.68% in the control group (P < 0.05). The satisfaction rate of patients and their families in the study group was 97.37%, which was significantly higher than 84.21% in the control group (P < 0.05).

CONCLUSION

Emergency nursing mode in patients with traumatic shock owns higher rescue value, can buy time for the operation, improve the success rate and effect of rescue, make safety and satisfaction higher. Overall, for patients with traumatic shock, emergency nursing mode is better than conventional rescue nursing.

Controversies and evidence gaps in the early management of severe traumatic brain injury: back to the ABCs

Traumatic brain injury (TBI) accounts for around 30% of all trauma-related deaths. Over the past 40 years, TBI has remained a major cause of mortality after trauma. The primary injury caused by the injurious mechanical force leads to irreversible damage to brain tissue. The potentially preventable secondary injury can be accentuated by addressing systemic insults. Early recognition and prompt intervention are integral to achieve better outcomes. Consequently, surgeons still need to be aware of the basic yet integral emergency management strategies for severe TBI (sTBI). In this narrative review, we outlined some of the controversies in the early care of sTBI that have not been settled by the publication of the Brain Trauma Foundation’s 4th edition guidelines in 2017. The topics covered included the following: mode of prehospital transport, maintaining airway patency while securing the cervical spine, achieving adequate ventilation, and optimizing circulatory physiology. We discuss fluid resuscitation and blood product transfusion as components of improving circulatory mechanics and oxygen delivery to injured brain tissue. An outline of evidence-based antiplatelet and anticoagulant reversal strategies is discussed in the review. In addition, the current evidence as well as the evidence gaps for using tranexamic acid in sTBI are briefly reviewed. A brief note on the controversial emergency surgical interventions for sTBI is included. Clinicians should be aware of the latest evidence for sTBI. Periods between different editions of guidelines can have an abundance of new literature that can influence patient care. The recent advances included in this review should be considered both for formulating future guidelines for the management of sTBI and for designing future clinical studies in domains with clinical equipoise.

Omega-3 Fatty Acids and Vitamin D Decrease Plasma T-Tau, GFAP, and UCH-L1 in Experimental Traumatic Brain Injury

Traumatic brain injury (TBI) results in neuronal, axonal and glial damage. Interventions targeting neuroinflammation to enhance recovery from TBI are needed. Exercise is known to improve cognitive function in TBI patients. Omega-3 fatty acids and vitamin D reportedly reduce inflammation, and in combination, might improve TBI outcomes. This study examined how an anti-inflammatory diet affected plasma TBI biomarkers, voluntary exercise and behaviors following exposure to mild TBI (mTBI). Adult, male rats were individually housed in cages fitted with running wheels and daily running distance was recorded throughout the study. A modified weight drop method induced mTBI, and during 30 days post-injury, rats were fed diets supplemented with omega-3 fatty acids and vitamin D₃ (AIDM diet), or non-supplemented AIN-76A diets (CON diet). Behavioral tests were periodically conducted to assess functional deficits. Plasma levels of Total tau (T-tau), glial fibrillary acidic protein (GFAP), ubiquitin c-terminal hydrolase L1 (UCH-L1) and neurofilament light chain (NF-L) were measured at 48 h, 14 days, and 30 days post-injury. Fatty acid composition of food, plasma, and brain tissues was determined. In rats exposed to mTBI, NF-L levels were significantly elevated at 48 h post-injury (P < 0.005), and decreased to levels seen in uninjured rats by 14 days post-injury. T-tau, GFAP, and UCH-L1 plasma levels did not change at 48 h or 14 days post-injury. However, at 30 days post-injury, T-tau, GFAP and UCH-L1 all significantly increased in rats exposed to mTBI and fed CON diets (P < 0.005), but not in rats fed AIDM diets. Behavioral tests conducted post-injury showed that exercise counteracted cognitive deficits associated with mTBI. The AIDM diets significantly increased docosahexaenoic acid levels in plasma and brain tissue (P < 0.05), and in serum levels of vitamin D (P < 0.05). The temporal response of the four injury biomarkers examined is consistent with studies by others demonstrating acute and chronic neural tissue damage following exposure to TBI. The anti-inflammatory diet significantly altered the temporal profiles of plasma T-tau, GFAP, and UCH-L1 following mTBI. Voluntary exercise protected against mTBI-induced cognitive deficits, but had no impact on plasma levels of neurotrauma biomarkers. Thus, the prophylactic effect of exercise, when combined with an anti-inflammatory diet, may facilitate recovery in patients with mTBI.
