Pneumothorax, pneumomediastinum, tracheo-esophageal fistula presenting with endotracheal intubation in post-cesarean period: A case report.

BACKGROUND: The non-malignant, acquired tracheoesophageal fistulas (TEF), resulting from tracheal intubation are usually iatrogenic lesions. Tracheal lesions resulting from intubation may occur and pneumomediastinum, pneumothorax or subcutaneous emphysema may develop due to the stream of air. CASE PRESENTATION: We present a-39-year old, Caucasian patient, developing severe hypoxia fallowing cesarean section under general anesthesia. The findings of the patient were diffuse subcutaneous emphysema; together with pneumothorax and pneumomediastinum TEF was diagnosed in the patient by bronchoscopy and eusophagoscopy performed due to cough and difficulty in swallowing developing after extubation. CONCLUSION: It is important to the clinicians to be aware of the TEF can be accompanied to the traumatic intubation and urgent endoscopy or water-soluble contrast radiography may be prudent.

Comparison of the effectiveness of metoclopramide, ondansetron, and granisetron on the prevention of nausea and vomiting after laparoscopic cholecystectomy.

BACKGROUND AND GOALS: A relatively high incidence of postoperative nausea and vomiting (PONV) occurs in patients undergoing a laparoscopic cholecystectomy. Prophylaxis of PONV is usually achieved with a single-dose antiemetic drug administered during the surgical procedure. The aim of the current study was to compare the antiemetic activity of different 5-hydroxytryptamine-3 receptor antagonists with that of metoclopramide. MATERIALS AND METHODS: In a randomised, double-blind study, 75 patients received the following: Group M, 10 mg metoclopramide; Group K, 40 mcg . kg(-1) granisetron; and Group Z, 15 mcg . kg(-1) ondansetron intravenously (IV) diluted in 20 cc 0.9% NaCl (n = 25 of each) i.v. immediately before the induction of anesthesia. The standard general anesthetic technique, which consisted of sevoflurane in air-oxygen and a fentanyl perfusion, was used. Nausea, vomiting, and safety assessments were performed continuously during the first 24 hours after anesthesia. RESULTS: There were no statistically significant differences for demographic data, American Society of Anesthesiology (ASA), operation duration, or anesthesia time among the three groups (P > 0.05). Evaluated nausea and vomiting scores in the first 3-hour period revealed that each of the drugs had a similar antiemetic effect (P > 0.05). Nausea and vomiting scores, evaluated between the 4-24 hours, also revealed that the group M scores were obviously higher than groups K and Z (P < 0.001). A comparison of incidences of dose administrations were statistically not significant among the groups (P > 0.05). CONCLUSIONS: Granisetron, when given prophylactically, resulted in a significantly lower incidence of PONV than metoclopramide and ondansetron, whereas metoclopramide was ineffective. Garnisetron may be an effective treatment in the proflaxy of PONV.
