Objective To study shorten the time of initial oral intake and fluid intake after general anesthesia in patients receiving oral and maxillofacial surgery,and to reduce the patient′s discomfort and adverse reactions and promote the postoperative recovery. Methods A total of 160 patients were divided into control group and observation group with 80 cases each by random digits table method from April to September in 2014. Patients in control group were allowed to take food orally 6 h after they emerged from anesthesia; while those in observation group were allowed to drink water after 2 h at emergence from anesthesia and take liquid food after 4 h. The mis-aspiration,the fasting glucose,blood pressure,heart rate and the rate of thirst,hunger,nausea,vomiting were observed. Results The rate of thirst, hunger, nausea, vomiting in observation group were significantly lower than those in control group(4 cases vs. 73 cases, 15 cases vs. 76 cases, 10 cases vs. 29 cases, 1 case vs. 7 cases), and there were significant differences, P<0.05, χ2=119.19, 94.83, 12.24, 4.74.The fasting plasma glucose level in observation group was higher than that in control group:(4.82 ±0.74) mmol/L vs. (4.06 ±0.62) mmol/L, and there was significant difference, P<0.05, t=-7.04. The incidence of mis-aspiration was 0 in two groups. The blood pressure and heart rate in control group after operation were lower than those before operation, P<0.05,the t value of systolic pressure, diastolic blood pressure and heart rate:-2.32,-2.03,-4.89 after operation of 1 h,-2.75,-10.54,-6.22 after operation of 3 h,-8.91,-14.76,-6.14 after operation of 5 h. There was no significant difference in blood pressure after operation of 1 h compared with that before operation in observation group, P>0.05, the t value of systolic blood pressure, diastolic blood pressure were-2.73,-2.56. Conclusion Shorten the time of taking food for patients undergoing the oral and maxillofacial surgery,in order to relieve uncomfortable symptoms,prevent hypoglycemia and the hemodynamic disturbance after anesthesia, and promote recovery,early postoperative feeding should be suggested on the premise that they are fully awake.

BACKGROUND: In alveolar cleft patients, the amount of bone stock after alveolar bone grafting is mostly measured and analyzed by two-dimensional imaging, which can result in a large error. OBJECTIVE: To evaluate the 6-month osteogenesis of alveolar bone graft in alveolar cleft patients using cone beam CT. METHODS:Alveolar bone grafting was performed in 25 patients with unilateral complete alveolar cleft. The patients were folowed up for 6 months after surgery and the osteogenesis of the bone graft was evaluated by CBCT. RESULTS AND CONCLUSION:After the surgery, the labial bone support was better than the palatal one. There were significant differences in the alveolar bone thickness of the cleft region and the normal region of the central incisor as wel as the alveolar bone thickness of the cleft region and the normal region of the canine tooth 0 mm distant to the alveolar crest. These findings indicate that the palatal bone support is less than the labial one, and the bone support of the central incisor is not satisfactory, which provide the basis for the tooth movement in the alveolar bone grafting and the orthodontics treatment.
