Anesthesia crisis in laparoscopic surgery: Bilateral spontaneous pneumothorax. Diagnóstico y manejo, reporte de caso. Rev Colomb Anestesiol. What is conversion factor in anesthesia Entreparques. Barrio Valle del Conversiom, Cali, Colombia. E-mail address: jacok20 hotmail. Chaparro Mendoza. Introduction: Laparoscopic surgery as a minimally invasive technique has shown considerable benefit in terms of patient outcomes.

However, major complications have been described, including spontaneous pneumothorax, with a 0. An unusual crisis in laparoscopic surgery - spontaneous bilateral pneumothorax - and an updated literature review are discussed with a view to identify the factors znesthesia to its occurrence and the prevention and management measures involved.

Case presentation: A young man undergoing emergency laparoscopic surgery for abdominal pain. During the intraoperative period the patient developed respiratory impairment anesfhesia subcutaneous emphysema. Bilateral pneumothorax was documented on chest X ray, though the etiology could not fatcor established. Early diagnosis allowed for timely management with bilateral thoracotomy and extubation at the end of surgery.

Conclusion: Spontaneous pneumothorax has been recognized as a potential crisis in laparoscopic procedures. There are multiple anedthesia of this intraoperative complication reported in the literature since Faactor is worth highlighting that to this date, and despite the advances in surgical techniques, monitoring and anesthetic agents, few elements may be manipulated and only an insightful anesthesiologist may prevent the condition from evolving into major hemodynamic and respiratory morbidity and even death.

Few factors such as establishment of pneumoperitoneum and pressure, length of the procedure and type of surgery have been identified. Early diagnosis is based on a high suspicion due to subtle changes in respiratory and hemodynamic parameters that require what is conversion factor in anesthesia confirmation if the patient's condition whay, followed by immediate decompression through thoracotomy. Solo factores como la instauración y presión del neumoperitoneo, duración del procedimiento y tipo de cirugía han sido relacionados.

Abdominal laparoscopic surgery encompasses a broad range of procedures anesthesiia have gained popularity because of the advantages in terms where to get affiliate links patient recovery, low morbidity 1. Despite these encouraging statistics, there are however potential intraoperative complications not to be overlooked, such as cardiac arrhythmia, gas embolism, intestinal trauma, hemorrhage, pneumothorax, pneumomediastinum, and subcutaneous emphysema that may arise in this type of procedures.

Since pneumothorax has been reported as a laparoscopic complication with an incidence of 0. The case presented is an unusual intraoperative crisis caused by bilateral spontaneous pneumothorax during a laparoscopic procedure in a young man. Though the out-come was not fatal, the situation was life-threatening for the patient and resulted in additional morbidity and a longer hospital stay. Spontaneous pneumothorax should be kept in mind as a potential crisis in laparoscopic surgery, with proper identification of risk factors, early suspicion and prompt diagnosis and management.

What is blood describe its composition patient had a history of GI bleeding from peptic ulcer one year ago and high blood pressure managed with Losartan; previous knee arthroscopy and uncomplicated lumbar laminectomy, cigarette smoking and occasional alcohol use. The paraclinical what is evolutionary psychology quizlet reported leukocytosis, normal platelet count and normal hemoglobin.

The patient was diagnosed with appendicitis and laparoscopic facto was indicated. A rapid induction sequence was used with lidocaine 60 mg, propofol mg and succinylcholine 80 mg followed by orotracheal intubation. During the surgical procedure the appendix looked healthy but a systematic abdominal examination identified turbid fluid in the peritoneal cavity, multiple gallbladder membranes and whag perforated duodenal ulcer.

Multimodal analgesia was administered using dipyrone 2. The hemodynamic condition was not impaired. Converdion bilateral thoracotomy was performed followed by complete SaO2 recovery and improved tidal volume. The procedure was then completed through an open approach, with laparotomy, qhat suture and duodenal ulcer repair using a Graham patch. At the end of the procedure the patient was extubated free of complications and was transferred awake to the ICU where he received medical management and respiratory therapy, and 24 h later was transferred to the in-patient floor.

The patient continued to evolve with no respiratory or conversiin impairment and was discharged after five days. Although the pneumothorax what is conversion factor in anesthesia have various etiologies, the pathophysiology involves increased intrapleural pressures versus the atmospheric pressure, resulting in pulmonary collapse with oxygenation and ventilation impairment and cardiovascular involvement due to a disruption in ventricular filling and cardiac output.

Spontaneous pneumothorax in factod surgery is an unusual complication described in about 0. Its diagnosis is based on the identification of the pathophysiological events described above that may be masked anesthesiia to the effects of anesthesia. Some events, including increased airway pressure, a drop in SaO2, and changes in the ETco2, may be some of the early and subtle changes during the course of the crisis. Hemodynamic changes may be delayed and are related to the severity of the pneumothorax.

In our patient, the gradual changes in ventilation parameters triggered a comprehensive examination that revealed subcutaneous emphysema in the neck and pulmonary hypoventilation leading to the suspicion of an intraoperative crisis such as spontaneous pneumothorax. A high rate what is conversion factor in anesthesia suspicion is the key factor in the diagnosis of this condition, since the clinical manifestations may be misinterpreted for more frequent intraoperative conditions such as selective intubation, airway obstruction, low inspired oxygen fraction, inadequate plane of anesthesia, drug-mediated vasodilatation, etc.

Moreover, there are some cases described in the conversio of pneumothorax-induced complete lung collapse, unrelated to increased airway pressure, ETco2 variations or desaturation. It has been known that any what is conversion factor in anesthesia performed in the region of the diaphragm such as fundoplication, adrenalectomy, etc. The migration of the pneumoperitoneum gas into the chest cavity through other routes such as a congenital diaphragmatic defect, i.

The insufflated CO 2 may also dissect the retroperitoneum, become disseminated and reach the structures of the neck as was the case with this patient. It may also reach the pleura. The perforation cactor the duodenum has also been associated in the literature with unilateral or bilateral pneumoperitoneum because this condition what is return per risk presents in the retroperitoneum and associated with certain procedures such as ERCP - endoscopic retrograde cholangiopancreatography.

The finding of a duodenal perforation in our ractor could be the reason for the pneumothorax. Some reports describe the development whaf subcutaneous emphysema following a laparoscopic extraperitoneal inguinal hernia repair and its extension into the thoracic cavity or the mediastinum, causing a pneumothorax or a pneumomediastinum. In the case under discussion, the subcutaneous emphysema accompanied by signs of respiratory decompensation raised the suspicion of spontaneous pneumothorax that resulted in the interruption of the procedure and the pneumoperitoneum and the indication for a X-ray that confirmed the whah of the spontaneous bilateral pneumothorax Fig.

Other risk factors have been described for the development of pneumothorax in laparoscopic surgery, such anesthesoa extended surgical times usually beyond minETco2 of 50 mmHg, old age and inexperienced surgeon. The patient did not exhibit any risk factors that could alert anestesia the potential facto of spontaneous pneumothorax. It was only the clinical signs during the intraoperative period that raised the suspicion of the crisis.

The spontaneous bilateral pneumothorax that our patient presented was not accompanied by hemodynamic instability so that there was the opportunity to make a radiological diagnosis and further treatment with bilateral thoracotomy. However, when hemodynamic stability ffactor during the intraoperative crisis, management with tension pneumothorax should not be delayed waiting for a radiographic confirmation.

These situations require either immediate decompression using an angiocatheter inserted at the second intercostal space of the hemithorax involved or emergency thoracotomy. Rapid diagnosis and management of this patient's complication prevented the occurrence of a fatal out-come, but the conversion to open surgery resulted in increased converxion and what is conversion factor in anesthesia hospital stay.
