Pharyngeal pack placement in minor oral surgery: A prospective, randomized, controlled study

We conducted a prospective, randomized, controlled study to investigate the influence of pharyngeal pack placement on postoperative nausea, vomiting, and throat pain after minor oral surgery. Our study group was made up of 80 patients-45 men and 35 women, aged 19 to 52 years (mean: 27.3)-who underwent a minor oral surgical procedure under general anesthesia. Patients were randomly assigned to one of three groups: 20 patients who received a pharyngeal pack under videolaryngoscopic guidance (video guidance group), 20 who had a pack placed blindly (blind insertion group), and 40 patients who received no pack at all (control group). Postoperative nausea occurred in only 4 patients (20%) in the blind insertion group (p < 0.007). No patient experienced postoperative vomiting. Postoperative throat pain occurred in all 20 video guidance patients (100%), in 17 of the blind insertion patients (85%), and in 20 of the controls (50%). The difference between the controls and each of the two pack groups was statistically significant (p < 0.006); the difference between the two pack groups was not significant.
