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.
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.
ObjectiveTo summarize the management of anesthesia during robotic off-pump coronary artery bypass grafting (CABG) with the da Vinci surgical system in minimal thoractomy.
MethodsFrom May 2011 to December 2014, 24 patients (20 males and 4 females) at the average age of 62.1±12.8 years underwent robotic off-pump CABG with the da Vinci surgical system in our hospital. All the patients underwent the continuous invasive blood pressure monitoring, endotracheal intubation with the double-lumen tube after induction of general anesthesia, fiber bronchoscope positioning, intraoperative application of one-lung ventilation, placing the Swan-Ganz floating catheter, and monitoring the echocar-diography (TEE) and blood gas analysis and indexes of hemodynamics.
ResultsAll the patients were stable during the anesthesia induction period. There was no severe hypoxemia and hypercapnia. The surgery was successful and there was no thoracotomy. All the patients left off breathing machine postoperatively.The duration of mechanical ventilation was 5.3±2.8 hours. All patients were moved out from ICU in 18 hours.There was no thoracotomy for hemostasis after surgery. All the patients were discharged on the fourth or fifth day postoperatively. There was no death relevant to surgery or perioperative complications. There was no recurrence of cardiovascular events on the 30th day,3 months and 6 months postoperative follow-up.
ConclusionThis anesthesia method is safe and effective. It is a rapid recovery way with the fewer complications, less suffering of the patients, reliable anesthesia management and high satisfaction of the patients'.
ObjectiveTo systematically review the protection effect of epidural anesthesia combined with general anesthesia versus general anesthesia alone in patients underwent cardiac surgery, so as to provide evidence for reducing complications of cardiac surgery.
MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 2, 2015), WanFang Data, CBM, and CNKI were searched to collect randomized controlled trials (RCTs) about epidural anesthesia combined with general anesthesia versus general anesthesia alone for patients underwent cardiac surgery from inception to February 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software.
ResultsA total of 35 RCTs involving 3 311 patients were included. The results of meta-analysis showed that, compared with the general anesthesia group, the combination anesthesia group had lower incidence of supraventricular tachycardias (RR=0.63, 95%CI 0.48 to 0.83, P=0.001) and shorter ICU stay time (SMD=-0.57, 95%CI -1.02 to-0.12, P=0.01), but there were no significant differences in the incidences of respiratory complications, myocardial infarction, stroke and mortality between the two groups (all P values >0.05).
ConclusionCurrent evidence shows that the combination of epidural anesthesia and general anesthesia has better protection effect than general anesthesia alone in cardiac surgery, but the influence on long-term prognosis still needs to be assessed. Due to the limited quality of included studies, the above conclusion still needs to be verified by more high quality studies．
ObjectiveTo explore the risk factors for death within 7 days after admission in trauma patients undergoing surgery under general anesthesia, and provide evidence for predicting the outcomes of those patients and guidance for clinical practices.MethodsThe basic information and perioperative data of trauma patients who underwent surgery under general anesthesia between January 1st 2019 and December 31st 2020 were collected from the Hospital Information System and the Anesthesia Information Management System. Patients who died within 7 days after admission were assigned into the case group and the others were assigned into the control group, and then propensity-score matching method was used based on age, sex, and injury types. Univariate analyses and multivariate binary logistic regression analysis were used to identify the risk factors for death within 7 days after admission in these patients.ResultsThere were 2 532 patients who met the inclusion criteria, of whom 96 patients with missing follow-up information were excluded, and 2 436 patients remained for the study. After propensity-score matching, there were 19 patients in the case group and 95 patients in the control group. The result of multivariate logistic regression analysis showed that the coma state at admission [odds ratio (OR)=9.961, 95% confidence interval (CI) (1.352, 73.363), P=0.024], perioperative body temperature<36℃ [OR=23.052, 95%CI (1.523, 348.897), P=0.024], intraoperative mean arterial pressure<60 mm Hg (1 mm Hg=0.133 kPa) [OR=12.158, 95%CI (1.764, 83.813), P=0.011], serum calcium concentraion<2.0 mmol/L [OR=33.853, 95%CI (2.530, 452.963), P=0.008], and prothrombin time [OR=1.048, 95%CI (1.002, 1.096), P=0.042] increased the risk of death within 7 days after admission.ConclusionThe coma state, coagulopathy, perioperative hypothermia, intraoperative hypotension, and hypocalcemia are 5 independent risk factors for death in trauma patients after surgery under general anesthesia.
ObjectiveTo evaluate if intravenous lidocaine can reduce the stress response induced by fiberoptic bronchoscopy in patients under general anesthesia.
MethodsSixty patients undergoing fiberoptic bronchoscopy under unconsciousness between November 2013 and July 2014 were randomly divided into two groups: lidocaine group (n=30) and control group (n=30). Patients in the lidocaine group received an intravenous injection of lidocaine for 1 mg/kg during induction and then continuous intravenous infusion of 2% lidocaine with a dose of 3 mg/(kg·h). The same volume of saline was given to patients of the control group in the same way. Laryngeal mask airway was placed after anesthesia induction. Variables of heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, and pulse oxygen saturation were observed and recorded at five time points: before induction, immediately after induction, immediately after laryngeal mask airway placement, fiberoptic bronchoscopy across tracheal carina and before leaving examination room. Complications including cough reflex, toxicity reaction of local anesthetics, and injection pain were also observed.
ResultsThe examination was successfully completed in all patients. Blood pressure and heart rate increased in all patients when fiberoptic bronchoscopy got across tracheal carina. There were no statistically significant differences in the two groups (P>0.05). Patients in the two groups had no statistic difference in tinnitus and numbness of tongue (P>0.05). Compared with the control group, patients in the lidocaine group had lower incidence of injection pain (P<0.05).
ConclusionIntravenous lidocaine cannot suppress stress response induced by fiberoptic bronchoscopy effectively.
Objective To assess the influence of dexmedetomidine on the recovery of pediatric patients after sevoflurane anesthesia. Methods Such databases as PubMed (1966 to March 2012), The Cochrane Library (Issue 1, 2012), EBSCO (ASP) (1984 to March 2012), Journals@Ovid Full Text (1993 to March 2012), CBM (1978 to March 2012), CNKI (1979 to March 2012), VIP (1989 to March 2012), and WanFang Data (1998 to March 2012) were searched to collect randomized controlled trials (RCTs) about the influence of dexmedetomidine on the recovery of pediatric patients after sevoflurane anesthesia, and the references of the included studies were also retrieved. Two researchers extracted the data and evaluated the methodological quality of the included studies independently. Then the RevMan 5.2 software was used for meta-analysis. Results A total of 16 RCTs involving 1 217 patients were included. The results of meta-analysis showed that, compared with the placebo, dexmedetomidine could reduce the occurrence of emergence agitation (OR=0.18, 95%CI 0.13 to 0.25, Plt;0.000 01) and increase the occurrence of postoperative lethargy (OR=0.14, 95%CI 0.03 to 0.68, P=0.01), but there were no differences in the occurrence of side effects including bronchospasm, bucking, breathholding, and oxygen desaturation. Dexmedetomidine could also reduce mean arterial blood pressure (MAP) and heart rate (HR) of pediatric patients during the recovery period after sevoflurane anesthesia, but it increased emergence time (MD=2.14, 95%CI 0.95 to 3.33, P=0.000 4), extubation time (MD=1.26, 95%CI 0.51 to 2.00, P=0.000 9) and the time of staying in PACU (MD=4.72, 95%CI 2.07 to 7.38, P=0.000 5). Conclusions For pediatric patients recovering from sevoflurane-based general anesthesia, dexmedetomidine can reduce the occurrence of emergence agitation, and is helpful to maintain the hemodynamic balance. But it prolongs emergence time, extubation time (or the time of using the laryngeal mask) and the time of staying in PACU, and increases the occurrence of postoperative lethargy.
Objective To assess the effectiveness and safety of laryngeal mask airway (LMA) and endotracheal tube (ETT) for airway management in pediatric general anesthesia. Methods Randomized controlled trials were collected through electronic searches of the PubMed, The Cochrane Library, EMbase, CBM, WanFang Data, VIP, CNKI from the date of establishment to November 2010. All the related data that matched the standards were abstracted by two reviewers independently. The quality of the included trials was evaluated according to the Cochrane Handbook 5.0. RevMan 5.0 software was used for meta-analysis of the complications, success of insertion on the first attempt and hemodynamic changes. Results A total of 39 trials involving 2 612 patients were included. The results of meta-analyses showed that LMA was superior to ETT in terms of less cough (RR=0.21, 95%CI 0.15 to 0.28, Plt;0.000 01), laryngospasm or bronchospasm (RR=0.37, 95%CI 0.18 to 0.77, P=0.008) and agitation (RR=0.14, 95%CI 0.09 to 0.22, Plt;0.000 01) during emergency. The incidence of postoperative sore throat (RR=0.32, 95%CI 0.19 to 0.55, Plt;0.000 1), hoarse voice (RR=0.09, 95%CI 0.03 to 0.27, Plt;0.000 1), nausea and vomiting (RR=0.46, 95%CI 0.26 to 0.80, P=0.006) was significantly lower in the LMA group. The hemodynamic changes during insertion and extraction of LMA were more stable than ETT, such as the heart rate changes in insertion, extraction and post-extraction period (SMD= –1.18, 95%CI –1.59 to –0.77, Plt;0.000 01; SMD= –1.29 95%CI –1.72 to –0.86, Plt;0.000 01; and SMD= –1.51 95%CI –2.15 to –0.87, Plt;0.000 01, respectively) and the MAP changes in insertion, extraction and post-extraction period (SMD= –1.21, 95%CI –1.39 to –1.02, Plt;0.000 01; SMD= –1.31, 95%CI –1.77 to –0.85, Plt;0.000 01; and SMD= –0.85, 95%CI –1.24 to –0.46, Plt;0.000 1, respectively); but no significant differences in postoperative regurgitation and aspiration (RR=3.00, 95%CI 0.62 to 14.61, P=0.17) and successful insertion on the first attempt (RR=0.99, 95%CI 0.94 to 1.05, P=0.84) were found between the LMA and ETT groups. Conclusion Current evidence indicates that the laryngeal mask airway is superior to endotracheal tube in terms of fewer complications during emergency and after operation as well as stable hemodynamic changes. So, it is a selective, safe and effective airway management for children.
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.
Objective To investigate change of bispectral index(BIS) and hemodynamic index during induction and orotracheal intubation of sevoflurane anesthesia. Methods This study was a prospective before-after study in the same patients. A total of 30 ASA physical status I and II adult patients without airway abnormalities were enrolled to receive inhalation induction of anesthesia with 8% sevoflurane. Mean arterial pressure(MAP),heart rate(HR) and BIS were recorded before anesthesia(T1),when patients loss of consciousness(T2), before intubation (T3),at 1 min(T4) and 3 min(T5) after intubation. Results BIS at T1-T5 were 96.8±1.7,70.4±8.8,39.2±8.4,43.6±12.9 and 41.6±9.3 respectively, the measurements at T2-T5 were all markedly lower than at T1(Plt;0.05). HR at T3-T5 were all markedly higher than at T1(Plt;0.05). MAP at T2 and T3 were markedly lower than at T1, but at T4 was higher than at T1(Plt;0.05), and recovered to the level at T1 at T5(Pgt;0.05).BIS,HR and MAP at T4 were all significantly higher than T3(Plt;0.05). Conclusion Anesthesia induction with sevoflurane and small dose of succinylchoiline we used can provide adequate depth of general anesthesia,but can not prevent cardiovascular adverse reactions to intubation.
