Role of combined propofol and sufentanil anesthesia in endoscopic injection sclerotherapy for esophageal varices

Figure 1 The patients were placed in the supine position. Electrocardiography, noninvasive arterial blood pressure monitoring, and pulse oximetry were performed as a part of the standard monitoring protocol. Sufentanil (0.5-1 μg/kg) was injected to induce mild sedation and restrain the stress response to intubation. Anesthesia was induced with 1-2 mg/kg of propofol and maintained with 2-5 mg/kg per hour of propofol. Scoline and cisatracurium were injected for the endotracheal intubation.

A: The patient was EV grade ≥ F2 and had a severe red color sign, according to endoscopic findings; B: Endoscopic injection sclerotherapy (EIS) was performed with a standard endoscope (SV-290; Olympus Corporation; Tokyo; Japan). The endoscopic puncture needle used in EIS was a 23-gauge Varixer needle; C: The endoscopic finding after EIS.
