Disseminated pneumocephalus secondary to air compressor injury

Pneumocephalus Secondary to Cerebral Air Embolism After Acute Bleeding in an Emphysema Bulla

Pneumocephalus is the presence of air in the intracranial space and has multiple causes, including cerebral air embolism. Its presentation may range from asymptomatic to decrease mental status, coma, and seizures. We present a case of cerebral air embolism secondary to acute bleeding inside an emphysema bulla. A 69-year-old female was brought to the emergency room after suffering acute dyspnea, convulsions, and cardiac arrest during a commercial flight. The Head CT showed the presence of multiple small gas collections in the brain, and the Thoracic Angiotomography showed a thin-walled bulla surrounded with pulmonary venous vascular structures and signs of active bleeding. The patient had rapid neurological deterioration with evolution to brain death due to anoxic encephalopathy before the possibility of treatment with pulmonary lobectomy and hyperbaric oxygen therapy. It is important to identify the localization of pneumocephalus to determine its etiology and to deliver the best treatment. Cerebral air embolism may happen when air enters the arterial or venous system, which can cause brain damage due to capillary leak syndrome and local ischemia. Treatment of pneumocephalus includes treating the cause, bed rest, avoidance of Valsalva maneuvers, positive pressure, and hyperbaric oxygen therapy. Early recognition is essential to prevent complications such as irreversible brain lesions and to improve patient outcomes.

Clinical Efficacy, Healing Efficacy, and Safety Analysis of Skin Orbicularis Oculi Muscle Combined with Tissue Flap for Eyelid Trauma

This study investigates the efficacy, healing efficiency, and safety of skin orbicularis oculi muscle combined with tissue flap repair for eyelid trauma patients. According to the different methods of surgical intervention, this study chooses 78 cases of eyelid injury patients. This study sets up the joint intervention group and the routine repair group, including the joint intervention group adopting the orbicularis oculi muscle skin of composite tissue flap to repair surgery. The routine repair group is treated by conventional repair skin flap transfer operation. Spearman correlation coefficient is used to analyze the correlation between postoperative healing of eyelid trauma patients and quality of life (SF-36) and self-image satisfaction (BIS) scale scores. The surgical intervention of skin orbicularis oculi muscle combined with tissue flap for patients with eyelid trauma has a better plastic repair effect in clinical practice. It can also effectively reduce the risk of postoperative complications, which is conducive to improve the postoperative quality of life and self-image satisfaction of patients.
