Risk of pulmonary aspiration during semaglutide use and anesthesia in a fasting patient: a case report with tomographic evidence.

Pulmonary aspiration of gastric residues during anesthesia is a potentially fatal complication for which no specific treatment is available. The primary way to prevent its occurrence in the context of elective surgeries is adherence to fasting protocols. However, some clinical conditions can prolong the gastric emptying time, and the risk of aspiration may exist despite adequate fasting. Recognizing the risk factors for gastroparesis allows the adoption of preventive methods and is the primary way to reduce morbidity and mortality from pulmonary aspiration. In this scenario, the anesthesiologist can investigate the gastric content by using ultrasound, adjust the anesthetic technique, and even postpone elective surgeries. Here, we describe incidental computed tomography finding of solid contents in the stomach of a patient without prior identification of the risk factors for gastroparesis. The patient underwent elective renal nodule ablation under general anesthesia after fasting for 9 hours. During the procedure, solid contents in the stomach were noted on computed tomography. Subsequently, it was discovered that the patient had been using semaglutide for 6 days and had not disclosed this information. Semaglutide use may represent a new and significant risk factor for anesthesia-related pulmonary aspiration. Until studies provide information on the appropriate perioperative management of patients using semaglutide, anesthesiologists need to adopt preventive measures to avoid aspiration. Awareness of this potential association and open communication among patients, physicians, and anesthesia teams are essential for enhancing patient safety.

Pressurized hydrodissection for CT-guided percutaneous peritoneal navigation: The hydro jet technique.

The purpose of this paper is to evaluate the effectiveness of a new technique of hydrodissection for peritoneal structures displacement during preoperative localization markers placement. We retrospectively reviewed two cases of percutaneous fiducial marker placement prior rescue retroperitoneal lymphadenectomy. In both cases pressurized 5% dextrose in water (D5W) was used to hydrodissect the peritoneal space and securely reach the lymph nodes. Two patients were submitted to water jet technique for transperitoneal trespassing to reach the retroperitoneum. The volume of fluid used to navigate was 125-200 mL and the mean time to cross the peritoneum was 6 min 47 s (ranging from 3″26' to 10″24'). In conclusion, Bowel and small vessels displacement using pressurized D5W is a safe method to reach retroperitoneal space during percutaneous procedures.
