ABSTRACT
@#AIM: To compare the clinical efficacy and safty of 25G and 27G pars planavitrectomy(PPV)in the treatment of rhegmatogenous retinal detachment(RRD)with air tamponade.<p>METHODS: Sixty-three cases(63 eyes)with RRD underwent 27G or 25G PPV from May 2016 to June 2018 were retrospectively reviewed. Thirty-three eyes(33 eyes)for 25G vitrectomy and 30 eyes underwent 27G vitrectomy. The main outcome measurements of the study included the best corrected visual acuity(BCVA, LogMAR), intraocular pressure, surgicaltime, retinal reattachment rate, intraoperative and postoperative complications.<p>RESULTS: There were no significant differences in baseline demographic between the two groups(<i>P</i>>0.05). The BCVA was increased significantly in both groups(all <i>P</i><0.01), but there was no significant difference in terms of visual improvement between the two groups(<i>P</i>>0.05). The mean surgical time in the 25G group was(44.13±5.9)min, which was no significant difference than that of 27G group(46.07±6.1)min(<i>t</i>=0.028, <i>P</i>=0.412). The retinal reattachment rate after a single operation was 91% and 93% for 25G and 27G group respectively(χSymbolr@@=0.015, <i>P</i>=0.902). There was no significant difference about hypotony(<6mmHg, 1mmHg=0.133kPa)between the 25G group(15%)and the 27G group(10%),(χSymbolr@@=0.376, <i>P</i>=0.540). No serious complication such as choroidal detachment and endophthalmitis was observed in both groups.<p>CONCLUSION: This study finds no significant differences in the surgical time, the rate of reattachment of retina, improvement of BCVA and complications between the 25G or 27G vitrectomy for rhegmatogenous retinal detachment with air tamponade. 27G vitrectomy with air tamponade seems to be a safe, economical and effective surgery for RRD.
ABSTRACT
AIM:To compare the clinical effects of 25G+ and 27G+ transconjunctival sutureless vitrectomy in treating idiopathic macular hole.METHODS: We retrospectively reviewed the clinical outcomes of 56 eyes (56 patients) with idiopathic macular hole which were treated with micro-incision vitrectomy from June 2015 to September 2016.Patients were divided into two groups, 28 patients (28 eyes) were treated with 25G+ vitrectomy and the rest (28 eyes) were treated with 27G+ vitrectomy.The operative time and intraoperative complications were recorded and patients were followed up for 3-6mo.During the follow up period, best correct vision acuity (BCVA), intraocular pressure, macular hole healing and postoperative complications were documented and statistically analyzed.RESULTS: BCVA in two groups were significantly improved after surgery(P<0.001) and there was no significant difference between the two groups(P=0.84).No serious complications occurred.No statistically significant difference was found between the two groups in surgical time and healing rate of macular hole (P=0.57, 0.64).The incidence of low intraocular pressure (IOP<10mmHg) in 27G+ group was lower than that in 25G+ group on the first day after surgery(P=0.31).There was no significant difference between preoperative and postoperative intraocular pressure at 1wk after operation in both groups (P=0.72, 0.92).CONCLUSION: Both 25G+ and 27G+ vitrectomy are safe and effective technique in treating idiopathic macular hole.Besides, 27G+ showed better superiority on the maintenance of intraocular pressure and reduce the trauma.
ABSTRACT
Background: Post dural puncture headache (PDPH) is a serious complication of spinal anaesthesia and incidence is more particularly in parturient. Aims & Objective: The present study was designed to investigate the use of 27 Gauge (G) spinal needle for spinal anaesthesia in Caesarean section in terms of success and PDPH rate. Material and Methods: We included total 50 female patients of aged 20-40 years old, were administered spinal anaesthesia with 27G Quincke spinal needle for Caesarean section by same investigator having enough experience. Redirections and attempts for lumbar puncture, success rates of spinal anaesthesia and PDPH were recorded. Results: We succeeded in 49 patients (98%) to administer spinal anaesthesia. The mean attempt and redirections for lumbar puncture were 1.1 and 1.24 respectively. We found PDPH in 1 patient (2%), which was mild in severity and subsided within two days. Conclusion: Spinal anaesthesia using a 27G Quincke spinal needle, in experienced hands can have successful spinal block with reduced PDPH rates in patients undergoing Caesarean section.
