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.
ObjectiveTo assess impact of typical parameters recommended by enhanced recovery after surgery (ERAS) program in elective colorectal surgery, and provide some recommendations for surgeon and anesthesiologist.
MethodThe published articles about ERAS program in elective colorectal surgery in recent years were searched in these databases(EMBASE, PubMed, Cochrane Library, Ovid), the impact of each parameter was evaluated basing on hospital stay and rate of postoperative complications.
ResultsAfter analyzing the literatures, the parameters, which were applied in current rehabilitation programs and covered the pre-, intraand post-operative periods in colorectal surgery, were identified as potential impacting consequences of colorectal surgery. Strong agreements were obtained for the following recommendations:① Preoperative management:bowel preparation, fasting, preanesthetic medication, and nutritional care.② Intraoperative management:fluid management, preventing hypothermia, method of surgery and incision, drugs usages of antibiotics, glucocorticoid and prevention of postoperative nausea and vomiting.③ Postoperative management:managements of drainage tube, nasogastric intubation and urinary catheter, postoperative analgesia, prevention of thromboembolism, and measures of intestinal function recovery (including early mobilization, feeding and chew gum).
ConclusionUse of a series of effective measures in ERAS has an effective result, could reduce surgical stress and complications, enhance recovery, shorten hospital stay.
Surgery is an important method for the treatment of malignant tumors. Sevoflurane is one of the most common general anesthetics, which can directly or indirectly affect the biological behavior of cells and the immune function of tumor patients, thereby affecting the recurrence and metastasis of tumor patients after surgery. From the aspects of microRNA, matrix metalloproteinase, phosphatidylinositol-3-kinase/Akt signaling pathway and hypoxia-inducible factor-1α, this article summarizes the molecular mechanisms of sevoflurane affecting the biological behavior of tumor cells, and clarifies the regulation mechanism of sevoflurane on the immune function of tumor patients. It is expected to provide a theoretical basis for precise anesthesia for tumor patients, and to provide medication basis for reducing postoperative recurrence and metastasis of tumor patients.
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 explore the effect of pain management by anesthesia nurses on labor analgesia.
Methods
A total of 100 parturient women in the Affiliated Hospital of North China University of Science and Technology between July and August 2015 were randomly divided into two groups: analgesia group and control group with 50 in each. Both two groups accepted labor analgesia routine maternity nursing. Analgesia group accepted maternal perinatal term pain management in addition to the routine nursing. Then we compared degree of pain during the production process, labor time and perineal injury between the two groups of women.
Results
The number of women with a labor pain degree of 0-Ⅲ in the analgesia group was respectively 36 (72%), 12 (24%), 2 (4%) and 0 (0%), and the number in the control group was respectively 23 (46%), 17 (34%), 8 (16%), and 2 (4%). The above difference between the two groups was statistically significant (Z=–2.908, P =0.004). The number of women with intact perineum, perineal injury of lateral and median cut, and Ⅰ-Ⅲ degree laceration in the analgesia group was respectively 31 (62%), 7 (14%), 8 (16%), 4 (8%) and 0 (0%); and the number in the control group was respectively 21 (42%), 12 (24%), 10 (20%), 7 (14%) and 0 (0%), also with significant difference between the two groups (Z =–2.028, P =0.043). The first and second labor stage of the analgesia group was (462.32±101.27) and (63.58±10.38) minutes, and was (568.27±113.28) and (76.92±11.24) minutes in the control group, with significant differences between the two groups (P<0.001). There was no statistically significant difference between the two groups in the third labor stage (5.78±3.02) and (5.97±2.96) minutes, (P=0.654).
Conclusions
The implementation of pain management by anesthesia nurses on labor analgesia can significantly reduce maternal labor pain, shorten the time of labor, and the condition of the perineal injury is mild and easily acceptable. It is worthy of clinical promotion.
The anesthetic work of day surgery should be guided by the standardized perioperative evaluation system. The evaluation methods and standards with strong operability and repeatability are the prerequisites to ensure the safety and efficiency of day surgery. For the assessment of patients’ preoperative physiological status, preoperative preparation and postoperative rehabilitation, standardized work procedures should be established to ensure patients’ medical safety to the greatest extent. Through summarizing the advanced management experience of day surgery anesthesia at home and abroad, and combining with the principled suggestions in The Consensus of Chinese Experts on Anaesthesia for Day Surgery, the First Affiliated Hospital of Dalian Medical University has repeatedly revised the perioperative anesthesia evaluation methods in practice, and gradually explored a comprehensive, rigorous and standardized perioperative anesthesia evaluation system. This paper will focus on the evaluation of perioperative anesthesia and postoperative follow-up procedures in day surgery.
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.

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.
Objective To investigate the preventive effect of rapid preoxygenation technique on hypoxia caused by respiratory depression during outpatient obstetrics-gynecology operations. Methods According to a computer-generated random sequence, a total of 120 ASA I-II patients undergoing outpatient obstetrics-gynecology operations were randomly allocated into the trial group or the control group, 60 in each group. Patients in the control group received preoxygenation with tidal volume breathing. Patients in the trial group received preoxygenation with eight deep breaths (DB) in 1 min before anesthesia. All patients were induced with midazolam 1 mg, fentanyl 1μg /kg and propofol 2 mg/kg, and were maintained with propofol when needed. The following parameters were observed, including the incidences of respiratory depression and apnea, the onset time of anesthesia, the total doses of propofol as well as the changes in PetCO2 and SpO2. Results No significant differences were observed in demographic characteristics, the onset time of anesthesia, the total doses of propofol, and the incidences of respiratory depression and apnea between the two groups (P gt;0.05). However, the SpO2 in the control group was decreased significantly with a higher incidence of hypoxia (Plt;0.05). Conclusions Rapid preoxygenation technique may increase the oxygen reserves and improve the tolerance to hypoxia. It is effective in avoiding hypoxia caused by respiratory depression and apnea during outpatient obstetrics-gynecology operations.
ObjectiveTo evaluate the difference between the tracheal intubation connected to conventional ventilation (TI-CV) and rigid bronchoscopy connected to high frequency ventilation (RB-HFV) under general anesthesia on patients with transbronchial cryobiopsy (TBCB).MethodA prospective, randomized, controlled trial was conducted in interstitial lung disease patients with TBCB from August 2018 to February 2019 in the First Affiliated Hospital of Guangzhou Medical University. According to the different methods of intubation, the patients were divided to a TI-CV group and a RB-HFV group randomly. The operating duration, extubation duration, total anesthesia time, heart rate, blood pressure and arterial blood gas analysis were collected and analyzed.ResultsSixty-five patients were enrolled. There were 33 patients with an average age of (48.0±15.0) years in TI-CV group and 32 patients with an average age of (48.8±10.8) years in RB-HFV group. The basic line of body mass index, pulmonary function (FEV1, FVC and DLCO), arterial blood gas (pH, PaO2 and PaCO2) and heart rate (HR), mean arterial pressure (MAP) had no significant differences between two groups. At the first 5 minutes of operation, the pH was (7.34±0.06) and (7.26±0.06), and the PaCO2 was (48.82±9.53) and (62.76±9.80) mm Hg in TI-CV group and RB-HFV group respectively, with significant differences (P=0.000). At the end of operation, the pH was (7.33±0.06) and (7.21±0.08), the PaCO2 was (48.91±10.49) and (70.93±14.83) mm Hg, the HR were (79.6±21.1) and (93.8±18.7) bpm, the MAP were (72.15±13.03) and (82.63±15.65) mm Hg in TI-CV group and RB-HFV group respectively, with significant differences (P<0.05). There were no differences in the operating duration and extubation duration between two groups. The total anesthesia time was (47.4±8.8) and (53.3±11.6) min with significant difference (P=0.017). Five minutes after the extubation, there were no significant difference in the pH, PaO2, PaCO2, HR and MAP between two groups. No serious complications occurred in either group.ConclusionsCompared with rigid bronchoscopy, TI-CV under general anesthesia is more conducive to maintain effective ventilation, and maintain the HR and MAP stable during the TBCB procedure. TBCB procedure should be performed by TI-CV under general anesthesia in patients with poor cardiopulmonary function.
