Objective To investigate the effects of lidocaine throat surface anesthesia on hemodynamics in patients with surgical operation. Methods From January 2013 to April 2016, 118 cases of patients with upper abdominal surgery in our hospital, were randomly divided into observation group (n=68) and control group (n=50), the observation group were given lidocaine throat surface anesthesia, the control group did not give the throat surface anesthesia, observed two groups before induction of anesthesia (T0), before intubation (T1) and after 1 min (T2), 5min (T3) and 10min (T4) intubation, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) and other indicators.Results The observation group T1 and T2 SBP, DBP, MAP were significantly lower than control group (P<0.05);observation group SBP at T4 was lower than control group (P<0.05);HR of observation group and control group was not statistically significant at each period;The incidence of cough and cough classification in observation group were 22.06% and (1.20 ±0.73), which were significantly lower than that of control group 58.00%and (3.18 ±0.57)(P<0.05).The observation group and the control group breathing recovery time and the time of opening eyes difference had no statistically significant.Conclusion The surface of lidocaine anesthesia can reduce the cardiovascular response to tracheal intubation in patients with surgery and postoperative cough.

Objective To investigate the clinical value of transumbilical single-port laparoscopic colorectal operation.Methods The clinical data of 25 patients with benign or malignant carcinoma at the upper part of the colon or rectum who were admitted to the No.4 People's Hospital of Zigong from January 2010 to December 2012 were retrospectively analyzed,and the clinical experience of transumbilical single-port laparoscopic colorectal operation was summarized.Surgical procedure was selected according to the position and nature of the lesion.Patients were followed up via out-patient examination and phone call till March 2013.Results Partial colorectal resection was done on 14 patients,radical resection of right colon on 1 patient,radical resection of transverse colon on 1 patient,radical resection of left colon on 1 patient,radical resection of sigmoid colon on 2 patients and radical rectectomy on 6 patients.The operation was successfully carried out on 22 patients,2 patients received four-port laparoscopic colorectal operation,and 1 patient was converted to open surgery.The median length of the incision of single-port laparoscopic colorectal operation was 3.8 cm (range,3.5-4.5 cm),and the operation time was (192 ± 32) minutes.The intraoperative blood loss was (61 ± 21)mL,and the median diameter of the tumor was 2.7 cm (range,1.0-5.0 cm).The median number of lymph nodes dissected was 7 (range,3-22),the mean time of postoperative anal exhaust time was 2 days (range,1-5 days),and the mean time of postoperative hospital stay was 8 days (range,6-20 days).The incidence of postoperative complications was 8.0％ (2/25),including 1 patient with wound infection and 1 patient with anastomotic leakage.The circumferential resection margins of radically resected specimens were negative in 11 patients.Twenty-two patients who received transumbilical single-port laparoscopic colorectal resection were followed up,and the median time of follow-up was 12 months.Colorectal liver metastasis was detected on 1 patient at postoperative month 10,and the other patients survived without tumor recurrence or metastases.Conclusions Transumbilical singleport laparoscopic colorectal operation is safe,micro-traumatic and feasible,and it also has less complication and good cosmetic effect.
