Background and Objective: Intraoperative hypotension is a common complication in general anesthesia that could result in different serious complications particularly in elderly patients. This Randomized Clinical Trial (RCT) aims to determine effective continuous infusion rate of norepinephrine to prevent intraoperative hypotension during spinal surgery under general anesthesia in elderly patients. Methods: This RCT was conducted on elderly patients (n= 108) undergoing general anesthesia for posterior lumbar spinal fusion. The patients were randomly divided into 0.030, 0.060, and 0.090 μg.kg-1.min-1 groups of norepinephrine infusion rates. The outcomes were assessed at entrance to operation room (T0), 15 mins after anesthesia induction (T1), 60 mins following surgery (T2), and immediately after surgery (T3). The intraoperative and postoperative complications and rehabilitation outcomes were comparatively assessed. Results: All three groups significantly reduced the incidence of delayed wound healing (0.030 vs. 0.060 vs. 0.090 μg.kg-1.min-1; 33.3% vs. 10% vs. 10%, P=0.024) and wound infection (26.7% vs. 6.7% vs. 6.7%, P=0.031). Intraoperative total fluid volume and colloids volume in the 0.030 group were significantly higher than 0.060 and 0.090 groups (P=0.005, P=0.003, and P=0.01, respectively). The 0.060 and 0.090 groups significantly increased mean-arterial-pressure than the 0.030 group at T2 and T3. Both 0.060 and 0.090 infusion rates significantly reduced intraoperative hypotension than 0.030 dosage (P=0.01 and P=0.003, respectively). The bradycardia incidence in the 0.090 group was significantly higher than the 0.030 (P=0.026) and 0.060 groups (P=0.038). The 0.060 group decreased the first intake by 1.4 hours (P=0.008) and first flatus by 1.1 hours (P=0.004) and postoperative hospital stay by 1 day (P=0.066). Conclusion: The 0.060 µg·kg-1·min-1 norepinephrine infusion combined with goal-directed fluid therapy exhibited adequate intraoperative management and postoperative outcomes.

Objective Restrictive fluid therapy is recommended in thoracoscopic lobectomy to reduce postoperative pulmonary complications, but it may contribute to hypovolemia. Goal-directed fluid therapy (GDFT) regulates fluid infusion to an amount required to avoid dehydration. We compared the effects of GDFT versus restrictive fluid therapy on postoperative complications after thoracoscopic lobectomy. Methods In total, 124 patients who underwent thoracoscopic lobectomy were randomized into the GDFT group (group G, n = 62) or restrictive fluid therapy group (group R, n = 62). The fluid volume and postoperative complications within 30 days of surgery were recorded. Results The total fluid volume in groups G and R was 1332 ± 364 and 1178 ± 278 mL, respectively. Group R received a smaller colloid fluid volume (523 ± 120 vs. 686 ± 180 mL), had a smaller urine output (448 ± 98 vs. 491 ± 101 mL), and received more norepinephrine (120 ± 66 vs. 4 ± 18 µg) than group G. However, there were no significant differences in postoperative pulmonary complications, acute kidney injury, length of hospital stay, or in-hospital mortality between the two groups. Conclusion Restrictive fluid therapy performs similarly to GDFT in thoracoscopic lobectomy but is a simpler fluid strategy than GDFT. Trial registration: This study has been registered at the Chinese Clinical Trial Registry (ChiCTR2100051339) ( http://www.chictr.org.cn/index.aspx ).

Abstract Background Postoperative delirium (POD) is a common phenomenon after spinal surgery. Intraoperative fluid management may affect POD. The aim of this study was to compare the effects of restrictive fluid therapy (RF) with those of goal-directed fluid therapy (GDT) on POD. Methods A total of 195 patients aged ≥ 50 years who underwent spinal surgery were randomly divided into two groups: the RF group and the GDT group. In group RF, a bolus of lactated Ringer’s solution was administered at a dose of 5 mL·kg-1 before the induction of anesthesia, followed by a dose of 5 mL·kg-1·h-1 until the end of surgery. For patients in the GDT group, in addition to the initial administration of lactated Ringer’s solution at 5 mL·kg-1, the subsequent fluid therapy was adjusted by using a continuous noninvasive arterial pressure (CNAP) monitoring system to maintain pulse pressure variation (PPV) ≤ 14%. The primary endpoint was the incidence of POD, assessed once daily with the Confusion Assessment Method-Chinese Reversion (CAM-CR) scale at 1–3 days postoperatively. The secondary endpoints were intraoperative fluid infusion volume, urine volume, mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), regional cerebral oxygen saturation (rSO2) value, lactic acid value, and visual analog scale (VAS) pain score at 1–3 days after surgery. Moreover, postoperative complications and the length of hospital stay were recorded. Results The incidence of POD was lower in the GDT group than in the RF group (12.4% vs 4.1%; P = 0.035) in the first 3 days after spine surgery. Compared to group RF, group GDT exhibited a significantly increased volume of intraoperative lactated Ringer’s solution [1500 (interquartile range: 1128 to 1775) mL vs 1000 (interquartile range: 765 to 1300) mL, P < 0.001] and urine volume [398 (interquartile range: 288 to 600) mL vs 300 (interquartile range: 200 to 530) mL, P = 0.012]. Intraoperative MAP, CI and rSO2 values were higher in the GDT group than in the RF group (P < 0.05). Moreover, the length of hospital stay [17.0 (14 to 20) days versus 14.5 (13 to 17.0) days, P = 0.001] was shorter in the GDT group than in the RF group. Conclusions GDT reduced the incidence of POD in middle- and old-aged patients undergoing spinal surgery possibly by stabilizing perioperative hemodynamic and improving the supply and demand of oxygen.

Abstract Background Goal directed fluid therapy (GDFT) based on cardiac output assessment has been shown to reduce complications and improve survival for people undergoing major general surgery. There are no reports of cardiac output evaluation being used to optimise the fluid administration for patients with acute pancreatitis who are in a general surgery admission ward. Methods The trial protocol has been published. 50 patients with acute pancreatitis were recruited, consented and randomly allocated to either ward-based GDFT with intravenous (IV) fluids administered based on stroke volume optimisation or standard ward care but with blinded cardiac output evaluation for 48 hours following hospital admission. Results Over a period of 20 months 50 of 142 screened patients were recruited demonstrating that it was feasible to recruit into a randomised trial of this nature in ward patients with acute pancreatitis. 36 (72%) completed the allocated 48 hours of goal directed fluids with 10 (20%) discharged within 48 hours and 4 withdrawals (3 GDFT and 1 SC).  Baseline characteristics of the groups were similar with only 3 participants having severe disease (6%, 1 GDFT, 2 SC). Similar volumes of IV fluids were administered in both groups (GDFT 5465 (1839) ml, SC 5211 (1745) ml). GDFT group had a lower heart rate, blood pressure and respiratory rate and improved oxygen saturations. GDFT was not associated with any harms. Complications of AP appear to be similar as was duration of stay in intensive care. Length of hospital stay was 5 (2.9) in GDFT and 6.3 (7.6) in SC groups. Conclusions Ward GDFT is feasible and shows a signal of possible efficacy in acute pancreatitis in this early-stage study. A larger multi-site RCT is required to confirm clinical and cost effectiveness.

Abstract Background Enhanced recovery after surgery (ERAS) program advocates implementation of perioperative goal-directed fluid therapy and reduced application of colloidal fluids. It should be used reasonably selectively in high-risk patients despite the clear efficacy of human albumin (HA). Therefore, it is vital to identify the risk factors for the use of HA. This study aims to determine the incidence and risk factors of HA administration in patients undergoing total hip or knee arthroplasty (THA, TKA). Methods We identified patients undergoing THA or TKA in multiple institutions from 2014 to 2016 and collected patient demographics and perioperative variables. The criterion of HA administration was defined as a postoperative albumin level < 32 g/L or 32 to 35 g/L for at-risk patients. We compared 14 variables between patients who received HA administration and those who did not after stratification by the preoperative albumin (pre-ALB) level. Multivariable regressions identified the independent risk factors associated with HA administration. Results In total, 958 (20.3%) of 4713 patients undergoing THA and 410 (9.7%) of 4248 patients undergoing TKA received HA administration. In addition to pre-ALB < 35 g/L, preoperative anemia (odds ratio [OR] 2.12, P = 0.001; OR 1.39, P < 0.001) and drain use (OR 3.33, P = 0.001; OR 4.25, P < 0.001) were also independent risk factors for HA administration after THA regardless pre-ALB < 35 g/L or not, and patients undergoing TKA diagnosed of rheumatoid arthritis or ankylosing spondylitis tended to receive HA administration regardless pre-ALB < 35 g/L or not (OR 3.67, P = 0.002; OR 2.06, P < 0.001). Conclusions The incidence of HA administration was high in patients undergoing THA or TKA, and several variables were risk factors for HA administration. This finding may aid surgeons in preoperatively identifying patients requiring HA administration and optimizing perioperative managements.
