An uncommon mechanism of brachial plexus injury. A case report

A Comprehensive Protocol to Prevent Brachial Plexus Injury During Ankylosing Spondylitis Surgery

PURPOSE

This article describes a comprehensive protocol to protect the brachial plexus when performing pedicle subtraction osteotomy for ankylosing spondylitis patients with thoracolumbar kyphosis.

DESIGN

A descriptive study was conducted.

METHODS

Records of 101 cases from October 2013 to December 2016 were retrospectively audited. The protocol included five items: (1) preoperative assessment of motion range and nerve function of limbs and trunks; (2) preoperative positioning according to the assessment results; (3) intra-operative somatosensory evoked potential and blood pressure monitoring; (4) intra-operative repositioning according to the monitoring alarm signals; and (5) postoperative neurological function check.

FINDINGS

Five patients showed impending brachial plexus injury indicators, including two who had a decrease in blood pressure and three who had a decrease in the amplitude of somatosensory evoked potential. After adjustment of position and soft pads, one patient had brachial plexus injury (0.99%) and the recovery time was 2 weeks.

CONCLUSIONS

With this comprehensive strategy, the brachial plexus could be effectively protected during the surgery.

A review of acute postoperative sialadenitis in children

OBJECTIVE

Acute postoperative sialadenitis is a previously described rare entity that has occurred following general anesthesia and has also been associated with prolonged neurosurgical procedures. We aim to better characterize this entity while performing a literature review regarding potential etiologies, diagnosis, airway management and treatment options.

METHODS

A retrospective chart review was performed at a pediatric tertiary care center from 2000 to 2014. Charts were selected for the study utilizing an ICD-9 diagnosis of sialadenitis occurring within two weeks of a surgical procedure. Data including age, gender, medical history, preoperative diagnosis, operation length, time to symptom onset, and subsequent management were collected. An additional literature review was performed focusing on reports of post-operative acute sialadenitis involving airway compromise.

RESULT

244 charts were reviewed and 4 patients met inclusion criteria. The average time to symptom onset was 4.3 days (range 1 h-12 days) following conclusion of the surgical procedure. Symptoms ranged from mild inflammation of the parotid gland to rapid swelling of the neck necessitating intubation. All patients were treated with standard sialadenitis treatment including hydration, antibiotics, and airway management as needed.

CONCLUSION

To our knowledge this is the first case series reviewing this entity specifically within the pediatric population. There appears to be two distinct categories of postoperative sialadenitis; one of which presents very acutely and results in massive neck swelling and airway compromise. It is important for practicing Otolaryngologists to be aware of this potentially life-threatening complication in the immediate postoperative period.

Brachial plexopathy as a complication of induced hypothermia following cardiac arrest

Induced hypothermia following cardiac arrest is a common treatment in the critical care unit. Topical cooling measures are easy to initiate and widely utilised. We report a case of brachial plexopathy occurring in association with topical cooling measures and discuss the diagnosis, management and avoidance of such complications.

Intraoperative brachial plexus injury during emergence following movement with arms restrained: a preventable complication?

Background

Despite considerable analysis and preventive strategies, brachial plexus injuries remain fairly common in the perioperative setting. These injuries range from brief periods of numbness or discomfort in the immediate postoperative period to, in rare cases, profound, prolonged losses of sensation and function. We present a case of an orthopedic surgery patient who suffered a brachial plexus injury while under anesthesia after trying to sit upright with his arms restrained.

Case presentation

After the uneventful placement of an intramedullary tibial nail, an 18 year old patient tried to sit upright with his arms restrained while still under the influence of anesthesia. In the immediate postoperative period, the patient complained of a profound loss of sensation in his left arm and an inability to flex his left elbow, suppinate his arm, or abduct and rotate his shoulder. Neurological examination and subsequent studies revealed a C5-6 brachial plexus injury. The patient underwent range of motion physical therapy and, over the next three months, regained the full function and sensation of his left arm.

Conclusion

Restraining arms during general anesthesia to prevent injury remains a wise practice. However, to avoid injuring the brachial plexus while the arms are restrained, extra caution must be used to prevent unexpected patient movement and to ensure gentle emergence.

Saturday night brachial plexus palsy

An unusual case of brachial plexopathy following an alcohol binge is presented. The patient developed numbness and weakness of his right hand and neurophysiological tests demonstrated that the lesion level was at the brachial plexus. MRI of the brachial plexus, cerebrospinal fluid examination and DNA analysis for hereditary neuropathy with liability to pressure palsies were normal. Repeated neurological examination and neurophysiological studies 60 days later were normal. A diagnosis of brachial plexus neuropathy consequent to non-traumatic stretching of the middle and the lower trunks was made.

The surgical treatment of brachial plexus injuries in adults

Posttraumatic brachial plexus palsy is a severe injury primarily affecting young individuals at the prime of their life. The devastating neurological dysfunction inflicted in those patients is usually lifelong and creates significant socioeconomic issues. During the past 30 years, the surgical repair of these injuries has become increasingly feasible. At many centers around the world, leading surgeons have introduced new microsurgical techniques and reported a variety of different philosophies for the reconstruction of the plexus. Microneurolysis, nerve grafting, recruitment of intraplexus and extraplexus donors, and local and free-muscle transfers are used to achieve optimal outcomes. However, there is yet no consensus on the priorities and final goals of reconstruction among the various centers.
