Objective To explore the effect of the feed-forward control on safety nursing of ophthalmologic day surgery patients under general anesthesia. Methods A total of 623 ophthalmologic day surgery patients under general anesthesia were retrospectively selected into the control group, who adapted the routine nursing in the Ophthalmic Day Surgery Center from January to December 2015; a total of 1 210 ophthalmologic day surgery patients under general anesthesia were retrospectively selected into the observation group, who received the feed-forward control of nursing safety management on the basis of routine nursing care from January to December 2016. The incidence rate of the adverse events and potential safety hazards and satisfaction rate were compared between the two groups. Results The incidence rate of the adverse events and potential safety hazards in the observation group (0.83%, 10/1 210) was lower than that in the control group (3.37%, 21/623), the satisfaction rate in the observation group (98.67%) was higher than that in the control group (97.11%), and the differences were statistically significant (P<0.05). Conclusion The application of feed-forward control in the safety care of patients during the ophthalmologic day surgery under general anesthesia can effectively reduce the incidence of adverse events and potential safety hazards, and ensure the safety of medical care.
ObjectiveTo explore the influence of general anesthesia with laryngeal mask and preoperative inhalation of budesonide aerosol on the incidence of respiratory adverse events during pediatric anesthesia recovery. MethodsA total of 100 child patients scheduled to undergoing inguinal hernia repair between December 2012 and February 2014 were randomly divided into two groups (group A and B) with 50 in each. All the patients underwent general anesthesia with laryngeal mask, while patients in group B inhaled budesonide aerosol before anesthesia. Then, we observed the incidence of adverse events in both groups, including laryngospasm, respiratory tract infection, and pulmonary complications. ResultsCompared with group A, patients in group B had a lower incidence of adverse events (P<0.05). ConclusionPreoperative application of budesonide aerosol inhalation can significantly reduce adverse events in the process of anesthesia recovery in children.
Objective To systematically evaluate the effects of magnesium sulfate on postoperative pain and complications after general anesthesia. Methods A literature search was conducted in following databases as The Cochrane Library, EMbase, PubMed, EBSCO, Springer, Ovid, CNKI and CBM from the date of establishment to September 2011 to identify randomized controlled trials (RCTs) about intravenous infusion of magnesium sulfate during general anesthesia. All included RCTs were assessed and the data were extracted according to the standard of Cochrane systematic review. The homogenous studies were pooled using RevMan 5.1 software. Results A total of 11 RCTs involving 905 patients were included. The results of meta-analyses showed that compared with the control group, intravenous infusion of magnesium sulfate during general anesthesia significantly reduced the visual analog scale (VAS) scores at the time-points of 2, 4, 6, 8, 16, and 24 hours, respectively, after surgery, the postoperative 24 hours morphine requirements, and the incidents of postoperative nausea and vomiting (RR=0.61, 95%CI 0.40 to 0.91, P=0.02) and chilling (RR=0.29, 95%CI 0.14 to 0.59, P=0.000 7). Although the incidents of bradycardia (RR=1.93, 95%CI 1.05 to 3.53, P=0.03) increased, there were no adverse events or significant differences in the incidents of hypotension and serum concentration changes of magnesium. Conclusion Intravenous infusion of magnesium sulfate during general anesthesia may obviously decrease the pain intensity, and the incidents of nausea and vomiting and chilling after surgery, without increasing cardiovascular adverse events and risk of hypermagnesemia. The results still need to be confirmed by more high-quality and large-sample RCTs.
Objective To study the influence of low-tidal volume and positive end expiratory pressure (PEEP) protective ventilation on cardiac output volume in elderly patients under general anesthesia. Methods From August 2012 to July 2014, 60 elderly patients undergoing selective surgery were divided into three groups with 20 patients in each. Group A was treated with conventional ventilation: tidal volume at 8 mL/kg, PEEP at 0 cm H2O (1 cm H2O=0.098 kPa); group B was treated with a tidal volume of 6 mL/kg and a PEEP of 5 cm H2O; group C was treated with a tidal volume of 6 mL/kg and a PEEP of 8 cm H2O. We then observed and analyzed the blood pressure, heart rate, cardiac output, arterial blood gas and airway mean pressure before induction of anesthesia (T0), 15 minutes of mechanical ventilation after the induction of anesthesia (T1), 60 minutes after anesthesia induction (T2), and 15 minutes after tracheal extubation (T3). Results In all the three groups, the mean arterial pressure and cardiac output were stable. In group B and C, central venous pressure increased significantly, the mean airway pressure and lung compliance increased, and the arterial oxygen branch pressure also increased significantly (P < 0.05). Conclusion Low-tidal volume combined with 5-cm H2O or 8-cm H2O positive end expiratory pressure lung-protective ventilation had a small influence on the cardiac output of elderly patients under anesthesia, which can be safely used.
ObjectiveTo systematically review the influence of dexmedetomidine on early postoperative cognitive dysfunction in adult patients after receiving noncardiac surgery under general anesthesia. MethodsThe randomized controlled trials (RCTs) about the influence of dexmedetomidine on the early postoperative cognitive dysfunction of patients after receiving noncardiac surgery with general anesthesia was searched in PubMed, EBSCO, Springer, Ovid, The Cochrane Library (Issue 1, 2013), CNKI, VIP, WanFang Data and Google Scholar up to November 30th, 2013. The references of included literature were also retrieved manually. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2. ResultsA total of 22 RCTs involving 1 356 patients were enrolled. The results of meta-analysis indicated that:a) dexmedetomidine reduced the incidence of postoperative cognitive dysfunction on the first day (RR=0.38, 95%CI 0.29 to 0.49, P < 0.001), on the seventh day (RR=0.55, 95%CI 0.23 to 1.29, P=0.17); improved postoperative MMSE scores after surgery (on the first day:MD=2.38, 95%CI 1.42 to 3.34, P < 0.001; on the seventh day:MD=0.92, 95%CI 0.16 to 1.68, P=0.02), and decreased the expression of inflammatory factor IL-6 (instant:MD=-11.96, 95%CI-18.45 to-5.46, P=0.000 3; after 24 h:MD=-7.50, 95%CI-13.73 to-1.27, P=0.02); and TNF-α (instant:MD=-4.09, 95%CI-7.02 to-1.16, P=0.006)) in patients. b) No significant difference was found between two groups (MD=-0.97, 95%CI-2.37 to 0.43, P=0.17). ConclusionDexmedetomidine can effectively reduce the early-stage postoperative cognitive dysfunction, improve MMSE scores after the operation, and reduce inflammatory reaction. In addition, due to the limited quantity and quality of studies included, larger sample, high quality RCTs are needed to verify the abovementioned conclusion.
Day surgery has been applied in practice since more than 30 years ago in western world, which could obviously reduce the length of hospital stay, accelerate the recovery of patients, and achieve desirable economic and social benefits. Despite of the common development of day surgery in various diseases, the application of day surgery in breast general anesthesia surgery is limited. No related management standard has been established. By summarizing the experience of breast cancer day-surgery, Xijing Hospital of Air Force Medical University has established a comprehensive management standard, including preoperation, intraoperation, and postoperation management. Meanwhile, the nursing, resource allocation, follow-up, and stuff management are all enrolled into the management standard, aiming to improve the development of day surgery in general anesthesia breast cancer operation.
ObjectivesTo systematically review the efficacy of lidocaine injected prior to tracheal extubation in preventing hemodynamic responses to tracheal extubation in general anesthesia.MethodsPubMed, Ovid, Web of Science, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of lidocaine administrated prior to extubation in preventing hemodynamic responses to tracheal extubation in patients undergoing general anesthesia from inception to October, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 and Stata 13.0 software.ResultsA total of 10 RCTs involving 525 patients were included. The results of meta-analysis showed that: compared with control group, lidocaine could reduce mean arterial pressure in 5 min after extubation (MD=–5.10, 95%CI –9.41 to –0.79, P=0.02), weaken the increase in systolic blood pressure caused by extubation from the moment before extubation to 5 minutes after extubation (before extubation: MD=–7.22, 95%CI –10.34 to –4.11, P<0.000 01; at extubation: MD=–14.02, 95%CI –19.42 to –8.62, P<0.000 01; 1 minutes after extubation: MD=–15.82, 95%CI –22.20 to –9.45, P<0.000 01; 3 minutes after extubation: MD=–12.55, 95%CI –20.36 to –4.74, P=0.002; and 5 minutes after extubation: MD=–12.05, 95%CI –20.35 to –3.74, P=0.004), and weakened extubation-induced increase in diastolic blood pressure at extubation (MD=–9.71, 95%CI –16.57 to –2.86, P=0.005). In addition, lidocaine inhibited heart rate in all time points except the moment of before and at 10 minutes after extubation.ConclusionsCurrent evidence shows that lidocaine can inhibit the increase in blood pressure and heart rate caused by extubation at certain times. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusions.
ObjectiveTo investigate the effect of etomidate and propofol on inflammatory cytokines and cortisol for patients with lung adenocarcinoma. MethodSixty patients scheduled for lung cancer surgery under general anesthesia were studied. All patients were randomly divided into an etomidate total intravenous anesthesia group (group E, 30 patients, 16 males and 14 females at age of 58.0±5.0 years) and a propofol total intravenous anesthesia group (group P, 30 patients, 17 males and 13 females at age of 55.0±5.0 years), with 30 patients in each group. ResultsThe concentration of IL-6 in serum of patients in the two groups at time points T1, T2 and T3 was significantly higher than those at time point T0 (P < 0.01). The concentration of IL-10 and TNF-α in serum of patients at time points T1 and T2 was significantly higher than those at time point T0 (P < 0.01). And the difference of the concentration of TNF-α in serum of patients at time points T0 and T3 was not statistically significant (P > 0.05). The level of Cor of patients in the group E at time point T0 was slightly higher than those at time point T1, but lower than that at time points T2 and T3. There was no statistical difference in the concentration of IL-6 and TNF-α in serum of patients between the two groups. The level of IL-10 of patients in the group E at time points T2 and T3 was lower than those in the group P (P < 0.05), but no significant difference was observed at the other time points. The concentration of Cor in the patients in the group E at time point T1 was lower than that in the group P (P < 0.01), but no significant difference was observed either at the other time points. ConclusionThe effect of etomidate used for maintenance of general anesthesia on the inflammatory factors is essentially similar to that of propofol.
Objective To determine the efficiency and safety of dexmedetomidine in general anesthesia. Methods Trials were located through electronic searches of the PubMed, EBSCO, OVID, Springer, Foreign Journals Integration System, CNKI, CMBdisk (from the date of establishment of the databases to April 2008). Bibliographies of the retrieved articles were also checked. Result A total of 25 trials involving 1 241 patients were included. The Meta-analysis showed: dexmedetomidine reduced peri-operative heart rate and blood pressure, reduced the occurrence of postoperative nausea and vomitting [RR=0.57, 95%CI (0.38, 0.84)], postoperative agitation [RR=0.29, 95%CI (0.17, 0.51)], shivering [RR=0.45, 95%CI (0.29, 0.68)], increase the occurrence of bradycardia [RR=2.16, 95%CI (1.58, 2.95)], hypotension [RR=2.97, 95%CI (1.42, 6.18)]. Dexmedetomidine reduced administration of thiopental, isoflurane and fentanyl, while there was no difference in muscle relaxant. Dexmedetomidine showed no difference in emergency time compared with the control group. As a result of low incidence of adverse reaction, dexmedetomidine showed superior in discharge time [WMD15.17, 95%CI (3.87, 26.46)]. Conclusions The limited current evidence shows that dexmedetomidine is better in maintaining the hemodynamic balance; reducing occurrence of nausea, vomiting, agitation and shivering; and reducing doses of anesthetics. In emergency time, dexmedetomidine shows no difference except discharge time.
Objective To explore the feasibility and safety of early feeding after arthroscopic surgery with general anesthesia. Methods One hundred patients undergoing arthroscopic surgery with general anesthesia between January and December 2017 were randomly divided into the routine feeding group and the early feeding group, with 50 cases in each group. In the routine feeding group, patients were feeding after anus gas passage or 6 hours after surgery. Under full assessment, patients in the early feeding group could drink or eat when recovered from anesthesia. The nausea, vomiting, abdominal distension, and thirst incidences and the comfort degree 6 hours after surgery, the time of first stand up on foot, and the length of hospital stay between the two groups were compared. Results There was no statistical difference (P>0.05) in the incidence of disgusting (10.0%vs. 22.0%), vomiting (6.0% vs. 16.0%), abdominal distention (4.0% vs. 12.0%) or length of hospital stay [(6.44±2.28) vs. (6.34±0.94) days]. The difference in the incidence of postoperative thirst (14.0% vs. 40.0%), the comfort degree 6 hours after surgery (2.36±1.21 vs. 4.14±1.53), the time of the first stand up on foot [(17.30±10.32) vs. (20.84±3.92) hours] were statistically significant (P<0.05). Conclusions Early feeding is safe and feasible for the postoperiative arthroscopic surgery after general anesthesia, and can improve the patients’ comfort degree.
