ObjectiveTo analyze the occurrence of arrhythmia in patients during the recovery period of anesthesia, in order to take appropriate measures in nursing care to ensure the safety of patients. Method We carried out a retrospective analysis of 18 931 general anesthesia post-operative patients (aged 16-84 years old) transferred to anesthesia recovery from September 2012 to July 2013, and we observed the incidence rate of arrhythmia, and documented the clinical manifestations of the patients. ResultsDuring the anesthesia recovery, out of 18 931 general anesthesia postoperative patients, 269 cases of arrhythmia occurred, and the incidence rate was 1.42%. Twenty minutes after nursing intervention and use of medication, the difference of systolic blood pressure, bradycardic heart rate, and tachycardic heart rate of the patients were statistically better than those beofre the treatment (P＜ 0.05) . ConclusionEarly discovery and analysis of arrhythmia in patients during anesthesia recovery, along with timely provision of analgesic and antiarrhythmic treatment can effectively improve the circulation status of the patients, thus ensure the safety of the patients during anesthesia recovery.
ObjectiveTo evaluate the clinical effects of nebulized lidocaine anesthesia and anesthesia with lidocaine and midazolam in patients with preoperative bronchoscopy. MethodsTotally, 136 inpatients between May 2002 and June 2013 with preoperative bronchoscopy were included in the study. The patients were randomly assigned to experimental group and control group with 68 patients in each. For patients in the experimental group, 8 mL of 2% lidocaine was administered through inhalation anesthesia, followed by 2-3 mg bolus of midazolam, and subsequently 0.5 mg of midazolam was administered every 2 minutes depending on patients' awareness. Patients in the control group accepted lidocaine alone for anesthesia. The clinical efficacy and adverse effects of both the two ways of anesthesia were observed. ResultsThe time of sustained and effective anesthesia was (24.5±2.8) minutes in the experimental group, as compared with (16.8±2.1) minutes in the control group (P<0.01). The average amount of consumption of lidocaine was (12.4±1.3) mL in the experimental group, as compared with (16.8±1.5) mL in the control group (P<0.01). The heart rate at 5 min after operation was (81.5±19.5) beats/min in the experimental group, as compared with (94.6±34.6) beats/min in the control group (P<0.01). The mean pulse oxygen saturation at 5 min after operation was (93.5±3.6)% in the experimental group, as compared with (88.2±13.3)% in the control group (P<0.01). ConclusionCombined application of lidocaine and midazolam before bronchoscopy is simple and feasible for anesthesia, which has higher success rate, lesser side effects and other reactions such as body movement and coughing.
Objective To research anesthetic management, pathophysiologic variation of adult-to-adult living donor liver transplantation (A-ALDLT) and to probe how to improve anesthetic quality of A-ALDLT. Methods The clinical data of 47 donors from Sep. 2005 to Jan. 2007 in West China Hospital were reviewed. Intraoperative vital signs, anesthetic management, perioperative serum levels of HGB， Alb， ALT， AST, TBIL， APTT， PT were measured， and complications were assessed. Results The physical condition of all donors were good before operations and were all in grade Ⅰaccording to ASA. Under general anesthesia of intravenous and inhalation, electrocardiogram, O2 saturation, blood pressure and body temperature were continuously monitored. A radial arterial catheter and a central venous catheter were placed. Blood lavement was utilized intraoperatively in all patients. All donors maintained stable life signs intraoperatively. The average intraoperative blood losses was （603.13±317.00） ml, and donors were transfused with autologous blood 〔(381.25±171.15) ml〕, with only 4 donors required homologous blood transfusion. HR and mean arterial blood pressure (MAP) showed no significantly variations intraoperatively (Pgt;0.05). Compared with controlled central venous pressure (CVP) before and right after hepatectomy, CVP increased significantly (P＜0.05) when intubation and abdomen-closing were carried. After hepatectomy and on the first day after operation, HGB and Alb decreased significantly (P＜0.05); ALT, AST and TBIL increased significantly (P＜0.05). Right after hepatectomy, PT increased instantly and significantly (P＜0.05); On the first day after operation, APTT began to increase significantly (P＜0.05). All donors came around completely and were extubated in the liver transplantation intensive care unit on the first day after operation. There were 3 cases (6.38%) of postoperative complication, which were biliary leakage, portal vein thrombosis and serious pleural effusion. Those 3 donors were cured after treatment. Conclusion Inhalation and intravenous general anesthesia of propofol, remifen-tanil and isoflurane can maintain stable life signs and reduce liver injury. Steady anesthesia, sufficient oxygenation and effective blood protection measures, for example, by decreasing CVP to prevent bleeding and by reclaiming autologous blood to avoid transfusing homologous blood, are keys for the safety of the donor and the prevention of complications.
Objective To investigate the curve correlation between ventilation pressure and tidal volume in assisted mechanical ventilation with facemask during anesthesia induction. Methods Between January and August 2015, 120 patients, American Society of Anesthesiology Ⅰ-Ⅱ, undergoing selective gynecological surgery were randomly divided into four groups: groups P5, P10, P15 and P20, with 30 patients in each group. Mask ventilation pressure for the four groups were respectively 5, 10, 15 and 20 cm H2O (1 cm H2O=0.098 kPa). Patients were ventilated by preset ventilation pressure and frequency based on different groups after loss of consciousness. Mean ventilation volume (mean value of three tidal volumes) and end-tidal carbon dioxide pressure (PetCO2) were recorded for analysis. Results There was no significant difference among the four groups in patient’s general condition (P>0.05). The tidal volume of assisted mechanical ventilation increased with ventilation pressure degrees, and the differences among the four groups were significant (P<0.05). After curve regression analysis, tidal volume and ventilation pressure showed a positive linear correlation when ventilation pressure was set at 5-20 cm H2O, and the correlation equation was: tidal volume = 33.612×ventilation pressure-53.155. PetCO2 in P5 group was lower than those in the other three groups (P<0.05), while there were no significant differences among groups P10, P15 and P20 (P>0.05). Conclusion When ventilation pressure is set at 5-20 cm H2O in assisted mechanical ventilation with facemask during anesthesia induction, tidal volume and ventilation pressure show a positive linear correlation.
ObjectiveTo discuss the intraoperative anesthesia management for complete thoracoscopic surgical atrial fibrillation (AF) ablation via the left chest. MethodsWe retrospectively analyzed the clinical data of 201 patients (106 males and 95 females aged 58.7±15.4 years) with AF underwent complete thoracoscopic surgical ablation via the left chest in Department of Cardiothoracic surgery, Xinhua Hospital From September 2010 through December 2013. ResultsAll the patients successfully underwent the minimally invasive ablation procedure. No patient required conversion to sternotomy during the surgery. The average time of operation was 104.9±37.2 min. During the ablation procedure, the patients' blood pressure and arterial oxygen saturation (SpO2) reduced at different levels. The average minimum arterial blood pressure was 44-79 (62.4±8.4) mm Hg. The average minimum SpO2 was 83%-95% (88.8%±3.1%). After the ablation, the patients' respiratory function and hemodynamic gradually recovered. The average heart rate was 40-108 (70.0±16.6) bpm when sinus rhythm was restored. The maintenance of sinus rhythm rate was 94.5% (190/201) at discharge. There was no early death, stroke, hemorrhage or permanent pacemaker implantation during perioperation. ConclusionComplete thoracoscopic surgical AF ablation via the left chest has some influence on patients' respiratory function and hemodynamic. Reasonable anesthetic management can ensure the minimally invasive ablation procedure safe and effective.
Objective To evaluate the effectiveness of thoracic epidural anesthesia (TEA) combined with general anesthesia (GA) versus GA alone on intrapulmonary shunting during one-lung ventilation (OLV). Methods We searched the Cochrane Library (Issue 4, 2009), the specialized trials registered in the Cochrane anesthesia group, PubMed (1966 to Dec. 2009), EMbase (1966 to Dec. 2008), CBM (1978 to Dec. 2009), VIP (1989 to Dec. 2009), CNKI (1915 to Dec. 2009), and handsearched Clinical Anesthesia Journal and Chinese Anesthesia Journal. Randomized controlled trials (RCTs) about the effectiveness of TEA combined with GA versus GA alone on intrapulmonary shunting during OLV were included, The methodological quality of included RCTs was evaluated by two reviewers independently, Meta-analysis was conducted using RevMan 5.0 software. Results Ten RCTs involving 506 patients were included. The results of meta-analyses showed that there were no significant differences in intrapulmonary shunting during OLV at different times-points of 5, 15, 20, 30, and 60 minutes after OLV. Conclusion Both TEA combined with GA and GA alone have the same Security during OLV. But owing to the low quality and small sample size of the included studies, further more well-designed, large sample size RCTs are needed.
Since the proposal of enhanced recovery after surgery (ERAS), significant progress has been made in different surgical fields, but ERAS in thoracic surgery is still in its infancy. This article summarizes the research results of scholars at home and abroad, and provides a comprehensive overview of the ERAS anesthesia management pathway during the perioperative period of thoracic surgery from the aspects of preoperative evaluation, anesthesia scheme selection, ventilation strategy, fluid management, temperature protection, pain management, postoperative nausea and vomiting, and early mobilization. The aim is to provide a reference for ERAS management in thoracoscopic lung cancer surgery.
Objective To assess the efficacy and safety of sevoflurane versus ketamine in the anesthesia of child short period surgery. Methods Such databases as EMbase, PubMed, The Cochrane Library, CNKI, VIP, CBMdisc, Ongoing Controlled Trial and Conference Articles were searched from their establishment to April 2011 to collect randomized controlled trials (RCTs) and the quasi-RCTs. The quality of those studies meeting the inclusive criteria was assessed, the data were extracted and the meta-analysis was conducted by using RevMan 5.1.1 software. Results Ten studies involving 600 participants were included. Seven studies showed that the intraoperative heart rate of the sevoflurane group was lower than that of the ketamine group (MD= –11.85, 95%CI –16.47 to –7.23, Plt;0.000 01). Nine studies showed that the revival time of the sevoflurane group was shorter than that of the ketamine group (MD= –29.05, 95%CI –37.98 to –20.12, Plt;0.000 01). Three studies showed that the anesthesia induction time of the sevoflurane group was shorter than that of the ketamine group (MD= –208.45, 95%CI –359.22 to –57.68, P=0.007). Six studies showed that the influence on mean arterial pressure (MAP) had no significante difference (MD= –4.86, 95%CI –10.02 to 0.29, P=0.06). Meanwhile, seven studies showed that the adverse events of the sevoflurane group were fewer than those of the ketamine group (Peto OR=0.29, 95%CI 0.20 to 0.40, Plt;0.000 01). Conclusion The results of this system review show that sevoflurane is more effective than ketamine with fewer adverse reactions, and it provides a new choice for clinical anesthesia for child short period surgery. However, ketamine is still the main drug in clinical anesthesia for the child short period surgery at present, so high quality studies are needed for further clinical researches.
Objective To evaluate the indications, effectiveness and complications of vitreoretinal surgery using the 25G transconjunctival sutureless vitrectomy system (TSV25G) under the topical anesthesia. Methods The clinical and follow-up data of 22 eyes of 22 patients undergone vitreo-retinal surgery using TSV25G under the topical anesthesia were retrospectively analyzed. All of the patients were monocular sickened, including idiopathic macular hole in 10 eyes, idiopathic macular pucker in 6, vitreoretinal traction syndrome in 4, and vitreous hemorrhage associated with branch retinal vein occlusion in 2. Peeling of epiretinal membrane and/or internal limiting membrane, intra ocular laser coagulation, air-fluid exchange and tamponiding of C3F8 were performed according to the condition of diseases. The postoperative follow-up was 1-11 months, with the mean duration of 6.4 months. The effect of analgesia, cooperation with the patients, operative effect and complications in and after the surgery were observed. Results The operations finished successfully in all of the eyes under the topical anesthesia. The operation duration ranged from 20 to 25 minutes with average of 22 minutes. The patients cooperated with the doctor well without any discomfort. Two days after the surgery, edema of the wounded conjunctiva was found, and recovered 7 days later. A light pigment dot on the surface of the sclera could be seen at the first month. The complic ations included transient increasing of intraocular pressure in 2 eyes, feather-like opacity of lens in 5 eyes, vitreous hemorrhage in 1 eye, and air-bleb under conjunctiva in 2 eyes. No other complications related with the cut were fo und. The macular hole closed in 9 eyes with idiopathic macular hole, and the other 1 had the smaller but not closed hole. Idiopathic macular pucker, vitreoretinal traction syndrome, and vitreous hemorrhage associated with branch retinal vein occlusion were cured successfully. Conclusions Vitreoretinal surgery using the TSV25G under the topical anesthesia has many advantages such as simple procedure, short operation time, micro-invasion, less complications and rapid revovery, and mainly serves simple manipulation in some simple diseases such as idiopathic macular hole, vitreo-retinal traction syndrome, and simple hemorrhage.

ObjectiveTo discuss the method and effectiveness of Wide-awake technique in flexor tendon tenolysis.MethodsThe clinical data of 16 patients (22 fingers) with flexor tendon adhesion treated by Wide-awake technique for flexor tendon tenolysis between May 2019 and December 2019 were retrospectively analyzed. The patients were all male, aged from 18 to 55 years old, with an average of 35 years old. Among them, 4 cases (7 fingers) after replantation of severed fingers, 4 cases (7 fingers) after flexor tendon rupture repair, and 8 cases (8 fingers) after open reduction and internal fixation of proximal fractures. The time from the original operation to this operation was 6-18 months, with an average of 8 months. The visual analogue scale (VAS) score was used to evaluate the patient’s pain during local anesthesia (when the first needle penetrated the skin), intraoperative, and 24 hours postoperatively; and the recovery of finger movement was evaluated by total finger joint active range of motion (TAM) evaluation system and Strickland (1980) standard after operation.ResultsIntraoperative hemostasis and anesthesia were satisfactory, and the patient could fully cooperate with the surgeon in active finger movements. There were different degrees of pain during local anesthesia (VAS score was 2-4), no pain during operation (VAS score was 0), and different degrees of pain after operation (VAS score was 1-8, 9 patients needed analgesics). All incisions healed by first intention after operation. All 16 cases were followed up 9-15 months with an average of 12 months. Finger function was significantly improved, no tendon rupture occurred. At last follow-up, the patients after proximal fracture open reduction and internal fixation were rated as excellent in 4 fingers and good in 4 fingers according to the TAM standard, and both were excellent according to the Strickland (1980) standard; and the patients after replantation of severed fingers and flexor tendon rupture repair were rated as excellent in 4 fingers and good in 10 fingers according to TAM standard, and as excellent in 6 fingers and good in 8 fingers according to Strickland (1980) standard.ConclusionWide-awake technique applied in flexor tendon tenolysis can accurately judge the tendon adhesion and release degree through the patient’s active activity, achieve the purpose of complete release, and the effectiveness is satisfactory; the effectiveness of tendon adhesion release surgery after fracture internal fixation is better than that of patients after tendon rupture suture and replantation.
