ABSTRACT

Objective:To explore the effect of goal-directed fluid therapy (GDFT) on the gastrointestinal function of patients after laparoscopic radical resection of cervical cancer.Methods:A total of 60 patients who were scheduled for laparoscopic radical resection of cervical cancer in Shanxi Provincial People's Hospital from October 2016 to September 2018 were selected. They were randomly divided into observation group and control group by random number table method, with 30 cases in each group. Patients in the observation group received GDFT, they were connected to the Flotrac/Vigile monitoring system, and the fluid supplementation was guided according to the changes in mean arterial pressure (MAP), stroke volume variability (SVV) and cardiac index, the goal was to maintain MAP≥60 mmHg (1 mmHg = 0.133 kPa), SVV≤13%, and cardiac index 2.5-4.0 L·min -1·m -2. The conventional fluid therapy was applied in the control group, and the liquid's input speed was adjusted according to the changes of MAP and central venous pressure (CVP) which were respectively maintained at 60-110 mmHg and 8-12 cmH 2O (1 cmH 2O = 0.098 kPa). The crystal/colloid input, bleeding volume and urine output were recorded. The first bowel sounds recovery time, exhaust time, postoperative hospitalization time, and the incidence of nausea and vomiting after surgery were recorded. Arterial blood and central venous blood were drawn before anesthesia induction and 12, 24 and 36 hours after operation to determine the concentrations of arterial blood lactate and central venous oxygen saturation (ScvO 2) as well as intestinal type fatty acid binding protein (IFABP). Results:Compared with the control group, the urine output was increased ( t = -7.738, P < 0.01), the crystal input was reduced ( t = -13.439, P < 0.01), the colloid input was increased ( t = -8.360, P < 0.01), the recovery time of first bowel sounds after surgery was shortened ( t = 6.694, P < 0.01), the exhaust time was shortened ( t = -10.326, P < 0.01), and the time of postoperative hospitalization was shortened ( t = -7.377, P < 0.01). The incidence of nausea and vomiting in the observation group were 10.0% (3/30) and 6.7% (2/30), which were lower than 33.3% (10/30) and 26.7% (8/30) in the control group ( χ2 = 4.812, P = 0.028; χ2 = 4.320, P = 0.038). Compared with the control group, the concentration of IFABP in the observation group was reduced at 12 h ( t = 2.983, P = 0.004), 24 h ( t = 6.452, P < 0.01), and 36 h ( t = -3.880, P < 0.01) after surgery; the concentration of lactate in the observation group was reduced at 12 h ( t = -7.377, P < 0.01), 24 h ( t = -6.036, P < 0.01), and 36 h ( t = -8.933, P < 0.01) after surgery; the value of ScvO 2 in the observation group was increased at 12 h ( t = 2.710, P = 0.009) and 24 h ( t = 2.387, P = 0.020) after surgery. Conclusion:GDFT can maintain the balance between oxygen delivery and oxygen consumption in the gastrointestinal mucosa cells, which can promote the recovery of gastrointestinal function of patients undergoing laparoscopic radical resection of cervical cancer.

ABSTRACT

Objective:To determine the median effective dose (ED 50) of 0.5% ropivacaine when combined with dexmedetomidine based on femoral nerve cross-sectional area for ultrasound-guided femoral nerve block. Methods:American Society of Anesthesiologists physical statusⅠor Ⅱ patients of both sexes, aged 18-64 yr, with body mass index of 20-30 kg/m 2, scheduled for elective open reduction and internal fixation for patella fracture or removal of patella fracture by internal fixation, were randomly divided into dexmedetomidine and ropivacaine group (group DR) and ropivacaine group (group R). In group DR, 0.5% ropivacaine and 0.5 μg/kg dexmedetomidine were injected.In group R, 0.5% ropivacaine was injected.Ultrasonic localization of femoral nerve was performed for measurement of the femoral nerve cross-sectional area, and 0.5% ropivacaine was injected based on the area.ED 50 was determined by Dixon′ s up-and-down sequential method.The initial dose was 0.22 ml/mm 2, and the difference between the two successive doses was 0.02 ml/mm 2.The effective block was defined as complete loss of pain sensation in the areas of anterior skin of knee joint, skin on the inner side of the calf and dorsal medial skin of the foot and the degree of motor block was in stages 1-3 assessed using Brunnstrom motor function within 30 min after nerve block.Nerve block was considered ineffective if pain occurred in any nerve distribution area mentioned above.The study was terminated if 7 effective and ineffective alternating waves occurred.ED 50 and 95% confidence interval (CI) were calculated using Probit analysis. Results:In group R, 27 patients were enrolled in the study, and ED 50 (95%CI) of 0.5% ropivacaine for ultrasound-guided femoral nerve block was 0.106 (0.069-0.125) ml/mm 2.In group DR, 23 patients were enrolled in the study, and ED 50 (95% CI) of 0.5% ropivacaine for ultrasound-guided femoral nerve block was 0.038 (0.011-0.059) ml/mm 2.Compared with group R, ED 50 of 0.5% ropivacaine for femoral nerve block was significantly decreased in group R. Conclusion:When combined with dexmedetomidine 0.5 μg/kg, ED 50 of 0.5% ropivacaine based on femoral nerve cross-sectional area for ultrasound-guided femoral nerve block is 0.038 ml/mm 2.

ABSTRACT

<p><b>BACKGROUND</b>In order to minimize the injury reaction during the surgery and reduce the morbidity rate, hence reducing the mortality rate of esophagectomy, minimally invasive esophagectomy (MIE) was introduced. The aim of this study was to compare the postoperative outcomes in patients with esophageal squamous cell carcinoma undergoing minimally invasive or open esophagectomy (OE).</p><p><b>METHODS</b>The medical records of 176 consecutive patients, who underwent minimally invasive esophagectomy (MIE) between January 2009 and August 2013 in Cancer Institute & Hospital, Chinese Academy of Medical Sciences, were retrospectively reviewed. In the same period, 142 patients who underwent OE, either Ivor Lewis or McKeown approach, were selected randomly as controls. The clinical variables of paired groups were compared, including age, sex, Charlson score, tumor location, duration of surgery, number of harvested lymph nodes, morbidity rate, the rate of leak, pulmonary morbidity rate, mortality rate, and hospital length of stay (LOS).</p><p><b>RESULTS</b>The number of harvested lymph nodes was not significantly different between MIE group and OE group (median 20 vs. 16, P = 0.740). However, patients who underwent MIE had longer operation time than the OE group (375 vs. 300 minutes, P < 0.001). Overall morbidity, pulmonary morbidity, the rate of leak, in-hospital death, and hospital LOS were not significantly different between MIE and OE groups. Morbidities including anastomotic leak and pulmonary morbidity, inhospital death, hospital LOS, and hospital expenses were not significantly different between MIE and OE groups as well.</p><p><b>CONCLUSIONS</b>MIE and OE appear equivalent with regard to early oncological outcomes. There is a trend that hospital LOS and hospital expenses are reduced in the MIE group than the OE group.</p>
