Bilateral tension pneumothorax during jet ventilation: a case report

Jet ventilation (JV) involves high-pressure ventilation for upper laryngeal laser procedures. Anesthetic management for the patient undergoing JV can be challenging, as complications of JV can include subcutaneous emphysema and tension pneumothorax. A 52-year-old woman with a diagnosis of vocal cord polyps presented for direct microlaryngoscopy and laser laryngoplasty with JV. Intraoperatively, the patient developed lack of bilateral chest movement and an audible change in jet-ventilatory sounds. The patient was reintubated with a standard endotracheal tube. Subsequent attempts to ventilate the patient failed. A diagnosis of bilateral tension pneumothorax was made. Immediate pleural decompression resulted in improved ventilatory and hemodynamic status. The purpose of this case report is to discuss the pathophysiology related to tension pneumothorax and anesthetic implications for management of cases involving JV.

Case report of tension pneumothorax related to acupuncture

Although recent prospective studies came to the conclusion that the incidence of adverse events following acupuncture can be classified as minimal, many cases of acupuncture-related pneumothorax have been published over the years, among them some cases of tension pneumothorax. In this case, a slender woman received acupuncture from a fully trained medical acupuncturist including needling of the points LU1 in the subacromial region and BL13, which is a paravertebral point at the level of the spinous process of the third thoracic vertebra. During the final treatment, she experienced difficulties in breathing and pain in the left chest. On x ray examination a tension pneumothorax was diagnosed. Even though pneumothorax is the most frequently reported serious complication related to acupuncture, it is not an inevitable complication of acupuncture, and in most cases involves negligence from inadequate consideration of basic anatomy.     

Bilateral tension pneumothoraces and subcutaneous emphysema following colonoscopic polypectomy: a case report and discussion of anesthesia considerations

A 78-year-old man presented preoperatively with severe abdominal pain, dyspnea, and subcutaneous emphysema in his face, neck, and chest approximately 8 hours after colonoscopy with a sigmoid polypectomy. A pneumoperitoneum, free air in the mesentery, pneumoretroperitoneum, pneumomediastinum, and bilateral pneumothoraces were diagnosed using radiography and computed axial tomography. He emergently underwent an exploratory laparotomy with colostomy following bilateral chest tube placement. At laparotomy, a perforation of the posterior sigmoid colon was identified at the site of earlier polypectomy. The patient remained intubated and mechanically ventilated for 3 days postoperatively. Perforations of the colon during colonoscopies are the most serious complication of the procedure. Continued insufflation of air or carbon dioxide into a perforated colon can result in extraluminal gas that can result in life-threatening tension pneumothoraces. This case examines the consequences of colonic perforation and the anesthetic management for the definitive surgical treatment of a posterior sigmoid wall perforation. Anesthesia providers' awareness of the risk factors for colonic perforation due to colonoscopy, early signs and symptoms of perforation, and knowledge of the surgical and anesthetic management of perforation could lead to early recognition and intervention and likely to improved patient outcomes.

Spontaneous tension pneumothorax as a complication of Coronavirus disease 2019: Case report and literature review

Primary spontaneous tension pneumothorax (STP) is a rare and life‐threatening condition. We report a case of COVID‐19‐pneumonia patient who developed STP as a complication. He had a prolonged hospital stay and was ultimately discharged asymptomatic. A systematic literature search was performed to review studies (N=12) reporting STP in the setting of COVID‐19.     

Cardiac arrest under anesthesia in a pediatric patient with Williams syndrome: a case report

Serial cardiac arrests occurred during the induction of a 3-year-old boy for elective 1-sided orchiopexy surgery and evaluation under anesthesia of previously placed ear tympanoplasty tubes. The child's history included Williams syndrome along with hypercalcemia and mild supravalvular aortic stenosis. The initial arrests included significant ST wave changes along with profound brodycardia, hypotension, and pulseless electrical activity requiring full resuscitation twice. The patient was transferred on an emergency basis to the intensive care unit (the surgery was cancelled), and a heart catheterization was scheduled for the following morning. The patient experienced several cardiac arrests during the cardiac catheterization procedure, necessitating emergency extracorporeal membrane oxygenation cannulation and immediate transfer to the operating room for emergency cardiac surgery. A thorough preoperative cardiac workup, including cardiac catheterization, electrocardiogram, and echocardiogram, may decrease mortality and morbidity in patients with Williams syndrome. However, cardiac catheterization has been associated with increased risk in this patient population.     

Simultaneous bilateral spontaneous pneumothorax: case report.

A 22-year-old previously healthy male was admitted to the emergency department for chest pain and dyspnea of 1-day's duration. He had a history of heavy smoking. The patient was cyanotic, agitated, and severely dyspneic. Lung auscultation revealed severe diffuse bronchospasm and equally diminished breath sounds on both sides. Nasotracheal intubation and mechanical ventilation were performed shortly after admission due to acute respiratory failure. Simultaneous bilateral spontaneous pneumothorax was diagnosed from the chest x-ray, and chest tube drainage was immediately performed bilaterally. Computerized tomography of the chest 1 month later showed diffuse emphysematous bullae of the lungs. The case presented here should increase physicians' awareness of this rare form of spontaneous pneumothorax and its diverse manifestations.     

Open pneumothorax resulting from blunt thoracic trauma: a case report

Cases of open pneumothorax have been documented as early as 326 BC. Until the last 50 years, understanding of the epidemiology and treatment of penetrating chest trauma has arisen from military surgery. A better understanding of cardiopulmonary dynamics, advances in ventilatory support, and improvement in surgical technique have drastically improved treatment and increased the survival rate of patients with penetrating thoracic trauma. Open pneumothorax is rare in blunt chest trauma, but can occur when injury results in a substantial loss of the chest wall. This case study presents an adolescent who sustained a large open pneumothorax as a result of being run over by a car. Early and appropriate surgical intervention coupled with coordinated efforts by all members of the trauma team resulted in a positive outcome for this patient.

Laryngeal mask anesthesia in children: a case report

The laryngeal mask airway has become one of the major tools of modern anesthesia airway management. Despite the fact that no time limit has been recommended regarding its safe use in spontaneously breathing children, or adults, there is still reluctance to use the laryngeal mask airway in operations of long duration. We report the case of an uneventful 5-hour long laryngeal mask anesthesia in a spontaneously breathing 11-year-old boy undergoing lower limb surgery.     

Nonopioid anesthesia for awake craniotomy: a case report

Awake craniotomy is becoming more popular as a neurosurgical technique that allows for increased tumor resection and decreased postoperative neurologic morbidity. This technique, however, presents many challenges to both the neurosurgeon and anesthetist. An ASA class II, 37-year-old man with recurrent oligodendroglioma presented for repeated craniotomy. Prior craniotomy under general anesthesia resulted in residual neurologic deficits. An awake craniotomy was planned to allow for intraoperative testing for maximum tumor resection and avoidance of neurologic morbidity. The patient was sedated with propofol, and bupivacaine was infiltrated for placement of Mayfield tongs and skin incision. Following exposure of brain tissue, propofol infusion was discontinued to allow for patient cooperation during the procedure. Speech, motor, and sensory testing occurred during tumor resection until resection stopped after onset of weakness in the right arm. The propofol infusion was resumed while the cranium was closed and Mayfield tongs removed. The patient was awake, alert, oriented, and able to move all extremities but had residual weakness in the right forearm. Awake craniotomy requires appropriate patient selection, knowledge of the surgeon's skill, and a thorough anesthesia plan. This case report discusses the clinical and anesthetic management for awake craniotomy and reviews the literature.
