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.

Methods A total of 480 patients at ASA grade Ⅰ-Ⅲ to be operated in the lower abdomen, perineum and lower limbs under CSEA from March to December 2009 were randomly divided into four groups: midazolam group (M group), propofol group Ⅰ (PA group), propofol group Ⅱ (PB group), and propofol group Ⅲ (PC group), with 120 patients in each group. All four groups of patients underwent CSEA at L2-3 or L3-4 and accepted pinal injection of 12-15 mg of 0.2% hypobaric bupivacaine. After the anesthetic plane was confirmed, patients in M group accepted 0.04-0.06 mg/kg of midazolam; patients in PA group accepted propofol at a loading dose of 0.50 mg/kg followed by continuous infusion at a dose of 2.00 mg/(kg•h); patients in PB group accepted propofol at a loading dose of 0.75 mg/kg followed by continuous infusion at a dose of 3.00 mg/(kg•h); patients in PC group accepted propofol at a loading dose of 1.00 mg/kg followed by continuous infusion at a dose of 3.75 mg/(kg•h). The change of hemodynamics including the mean arterial pressure (MAP) and the heart rate (HR), bispectral index (BIS) values, sedation scores, memory of pictures seen during operation and adverse effects before drug administration (T0), at minute 1 (T1), 3 (T2), 5 (T3), 10 (T4), 30 (T5) and 60 (T6) after drug administration were observed. Results MAP and HR decreased in all the four groups after administration of sedatives, but the changes of measured values were within normal ranges. BIS value and the Observer’s Assessment of Alertness and Sedation (OAA/S) scale decreased in all groups at T3, compared with those at T0 (Plt;0.05). Compared with the other 3 groups, BIS valueand OAA/S scale were significantly lower in PC group at T4, T5 and T6 (Plt;0.05), and the satisfaction rate of sedation and amnesia was much higher. No serious glossocoma, apnea and SpO2 below 90% was observed in all the four groups. Conclusion During the surgery of lower abdomen and lower limbs, application of CSEA combined with propofol at a loading dose of 1.00 mg/kg followed by continuous infusion at a dose of 3.75 mg/(kg•h) can achieve a good sedative effect, with little side effect.

Methods Forty patients of ASA class Ⅰ or Ⅱ were randomly divided into group A and B,20 patients in each group. Anesthetic depth was judged and anesthetics was administered by BIS monitoring (being kept in 50±5) in group A or based on the experience of anesthetist in group B. After anesthesia induction, target propofol and remifentanil concentrations were adjusted to maintain the MAP, HR within the range of ±20% of preinduction values. Systolic pressure (SBP), distolic pressure (DBP), HR, SpO2 and BIS were monitored. Awake time and anesthetic consumption were recorded. Results The changes of SBP, DBP, HR and BIS were less in group A than those in group B (Plt;0.05).Awake time was shorter in group A than that in group B and restlessness drowsiness, nausea and vomitting after extubation were less in group A than those in group B. No awareness patient during operation was seen in group A, but one patient suffered from awareness in group B. Conclusion BIS monitoring can dynamicly reflect cerebral physilological function during general anesthesia and is helpful in judging anesthesia depth and directing the administration of anesthetics.
We reviewed the research progress of anesthesia management in hepatic echinococcosis surgery in recent years, including the key technologies, practical experience, and research progress of anesthesia management in hepatic echinococcosis surgery, so as to guide clinical practice. Firstly, in the selection of anesthesia, the general anesthesia combined with epidural block or regional nerve block is recommended to improve surgical safety and patients’ comfort. At the same time, the importance of intraoperative continuous monitoring, including key indicators such as hemodynamics and respiratory function, is emphasized, and transesophageal echocardiography and brain function monitoring techniques are introduced to optimize anesthesia management. Finally, the concept of enhanced recovery after surgery is promoted, and measures such as preoperative optimization, intraoperative heat preservation, refined fluid management, and postoperative analgesic management are implemented to promote the rapid recovery of patients. At the same time, some challenges and unsolved problems in the current research also are pointed out, such as complex case evaluation, complications prevention, and teamwork, etc., which need to be further studied in the future to optimize the anesthesia strategy.
