ABSTRACT
Air embolism is a rare and life-threatening event that occurs when air enters the cardiovascular system, usually secondary to iatrogenic vascular procedures. We present a 58-year-old woman who underwent a dental procedure (devitalization of a tooth) under local anesthesia, with a sudden onset of coma during manipulation and documentation of air in the vessels of the right frontal convexity sulci. After cerebral air embolism was confirmed, she received hyperbaric oxygen therapy, with resorption of the gas, but clinically she developed a super-refractory status epilepticus with a persistent coma. The slow clinical course required the exclusion of other etiologies of coma. The pathophysiology is not well known; however, it appears to be related to the injection of air by the high-speed dental drill through the soft tissue adjacent to the roots of the teeth, nearby the bloodstream. We highlight this event because of this unlikely association, which may delay diagnosis and the good results of hyperbaric medicine on prognosis.

Introduction Cancer remains one of the leading causes of death worldwide, with 5060% of patients requiring radiotherapy during the course of treatment. Patients survival rate has increased significantly, with an inevitable increase in the number of patients experiencing side effects from cancer therapy. One such effect is late radiation injuries in which hyperbaric oxygen therapy appears as complementary treatment.

INTRODUCTION: Cancer remains one of the leading causes of death worldwide, with 50-60% of patients requiring radiotherapy during the course of treatment. Patients' survival rate has increased significantly, with an inevitable increase in the number of patients experiencing side effects from cancer therapy. One such effect is late radiation injuries in which hyperbaric oxygen therapy appears as complementary treatment. With this work we intend to divulge the results of applying hyperbaric oxygen therapy among patients presenting radiation lesions in our Hyperbaric Medicine Unit. MATERIALS AND METHODS: Retrospective analysis of clinical records of patients with radiation lesions treated at the Hyperbaric Medicine Unit assessed by the scale Late Effects of Normal Tissues-Subjective, Objective, Management, Analytical (LENT-SOMA) before and after treatment, between October 2014 and September 2019 were included. Demographic characteristics, primary tumor site, subjective assessment of the LENT-SOMA scale before and after treatment were collected and a comparative analysis (Students t test) was done. RESULTS: 88 patients included: 33 with radiation cystitis, 20 with radiation proctitis, 13 with osteoradionecrosis of the mandible and 22 with radiation enteritis. In all groups, there was a significant decrease (p < 0.005) in the subjective parameter of the LENT-SOMA scale. DISCUSSION: Late radiation lesions have a major influence on patients' quality of life. In our study hyperbaric oxygen therapy presents as an effective therapy after the failure of conventional treatments. CONCLUSION: Hyperbaric oxygen therapy is an effective complementary therapy in the treatment of refractory radiation lesions.

INTRODUCTION: Pneumocephalus is a rare neuraxial blockade complication, which can be associated with severe neurologic changes. CLINICAL CASE: A 51-year-old patient was submitted to left total knee arthroplasty. Postoperatively, a pneumocephalus associated with decreased consciousness was diagnosed as a complication of the epidural analgesia. The treatment used was Hyperbaric Oxygen Therapy (HBOT) due to the severity of symptoms. Just after one session of HBOT, there was nearly full pneumocephalus resorption and significant clinical recovery. CONCLUSION: This case report enables anesthesiologists to recognize HBOT as a therapeutic option to be considered when treating severe cases of pneumocephalus.
