Abstract
BACKGROUND To determine the safety and feasibility of sutureless pars-plana vitrectomy (ppV) in sub-Tenon anesthesia. METHODS In this prospective study. Pain and anxiety at various times after ppV using a visual analogue scale (VAS) and Wong-Baker-FACES scale as well as visual sensations during surgery were investigated. The surgeon evaluated motility, chemosis, overall feasibility. RESULTS ppV was performed on 67 eyes (33 sub-Tenon anesthesia, 34 general anesthesia). Pain during surgery in sub-Tenon anesthesia was 1.8 ± 2.2 (0.0-8.0), anxiety was 2.3 ± 2.2 (0.0-8.5). There was a moderate correlation between pain and anxiety (R2 = 0.58). Comparing sub-Tenon and general anesthesia no difference in pain perception was found the day after surgery. 27.3% of patients saw details, 21.2% saw colors, 90.1% saw light/motion perception, 3.0% had no light perception. Median chemosis after surgery was 1.0 (IQR = 1.0). Median motility of the eye during surgery was 1.0 (IQR = 1.0), median grade was 1.0 (IQR = 1.0). 24.2% of patients showed subconjunctival hemorrhage during or after surgery. CONCLUSIONS Sutureless pars-plana vitrectomy in sub-Tenon anesthesia was performed safely, with pain and anxiety levels tolerable for the patients and without the necessity for presence of an anesthesiologist. With 88.9% of patients willing to undergo vitreoretinal surgery in sub-Tenon anesthesia again, we recommend it as a standard option. Trial registration This study was approved by the Institutional Ethical Review Board of the RWTH Aachen University (EK 111/19). This study is listed on clinicaltrials.gov (ClinicalTrials.gov identifier: NCT04257188, February 5th 2020).

Adequacy of Anaesthesia for Nociception Detection during Vitreoretinal Surgery. Life (Basel) 2023; 13:life13020505. [PMID: 36836862 PMCID: PMC9967373 DOI: 10.3390/life13020505] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/27/2023] [Accepted: 02/09/2023] [Indexed: 02/16/2023] Open
Abstract
Vitreoretinal surgery (VRS) is one of the most widely performed precise procedures in ophthalmic surgery; the majority of cases are carried out under regional anaesthesia (RA) only. However, in specific situations (such as when the patient fails to cooperate with the operator for various reasons), general anaesthesia (GA), alone or in combination with GA (combined general-regional anaesthesia, CGR), is the only safe way to perform VRS. While monitoring the efficacy of an intraoperative rescue opioid analgesia (IROA) during surgery (assessing the adequacy of anaesthesia (AoA)) may be challenging, the surgical pleth index (SPI) is a useful tool for detecting the reaction to noxious stimuli and allows for the rational titration of opioid analgesics (AO) during surgery. The current study investigated the influence of the SPI-based titration of fentanyl (FNT) in combination with various pre-emptive analgesia (PA) techniques on intraoperative pain perception during various stages of VRS performed under AoA. A total of 176 patients undergoing VRS under GA were enrolled in the study. They were randomly assigned to one of the five following study arms: Group GA (control group)-patients who received general anaesthesia alone; Group PBB-GA with preprocedural peribulbar block (with 0.5% bupivacaine and 2% lidocaine); Group T-GA with preventive, topical 2% proparacaine; Group M-GA with a preprocedural intravenous infusion of 1.0 g of metamizole; and Group P-GA with a preprocedural intravenous infusion of 1.0 g of paracetamol. The whole procedure was divided in four stages: Stage 1 and 2-preoperative assessment, PA administration, and the induction of GA; Stage 3-intraoperative observation; Stage 4-postoperative observation. the SPI values were monitored during all stages. The occurrence of nociception (expressed as ∆SPI >15) during various manipulations in the surgical field was observed, as were cumulative doses of rescue analgesia, depending on the PA administered. During the course of VRS, rescue FNT doses varied depending on the stage of surgery and the group investigated. The majority of patients, regardless of their group allocation, needed complementary analgesia during trocar insertion, with Group GA patients requiring the highest doses. Likewise, the highest cumulative doses of IROA were noted during endophotocoagulation in Group GA. Preventive PBB and topical anaesthesia were proven to be most efficient in blunting the response to speculum installation, while topical anaesthesia and paracetamol infusion were shown to be more efficient analgesics during endophotocoagulation than other types used PA. In the performed study, none of the PA techniques used were superior to GA with FNT dosing under the SPI with respect to providing efficient analgesia throughout the whole surgery; there was a necessity to administer a rescue OA dose in both the control and investigated groups.

Abstract
Purpose To compare pain during pars plana vitrectomy (PPV) following topical lidocaine jelly and sub-Tenon anesthesia versus peribulbar anesthesia. Methods Prospective, single-center, randomized study. Patients scheduled for PPV for macular hole (MH) or epiretinal membrane (ERM) at the Retina and Vitreous Section of the Department of Ophthalmology, Ribeirão Preto Medical School, University of São Paulo were randomly assigned to one of two groups in a 1:1 allocation ratio. Patients assigned to Group ST received topical anesthesia with 2% lidocaine jelly followed by sub-Tenon anesthesia with 2–4 ml of 1% ropivacaine. Patients assigned to PB received peribulbar anesthesia with 4–6 ml of 1% ropivacaine. After PPV, patients in both groups were asked to rate the level of pain they felt during the entire procedure (including anesthesia administration and PPV) by pointing at a 0–100 Visual Analogue Pain Scale (VAS). Data regarding demographics, patient characteristics and surgical features were also collected. Results Fifty-four patients were enrolled in the study (26 in Group ST and 28 in Group PB). Baseline characteristics, including age, gender, and presence of comorbidities, were similar in both groups. The surgery performed was PPV alone in 10 and 14 patients in the ST and PB groups, respectively, and combined phacoemulsification and PPV in 16 and 14 patients in the ST and PB groups, respectively (p = 0.39, Pearson). Surgery duration (mean ± SD minutes) was similar in the two groups (62 ± 12 for ST and 70 ± 20 for PB, p = 0.09, t-Test). No patients needed supplemental topical or intravenous anesthesia during surgery. No sight- or life-threatening complication was observed in either group. VAS score was significantly lower in the ST compared to the PB group (median (interquartile range) was 1 (2.25–0) in the ST group compared to 11.5 (29.75–5) in the PB group, p< 0.0001, Wilcoxon). Conclusion In this study of patients who underwent PPV for MH or ERM, topical followed by sub-Tenon anesthesia was more effective in controlling pain during the whole vitrectomy procedure than peribulbar anesthesia. Compared to peribulbar anesthesia which is administered with a sharp needle, sub-Tenon anesthesia administered with a blunt cannula may be associated with a reduced risk of such adverse events as globe perforation, retrobulbar hemorrhage, and inadvertent injection of anesthesia into the optic nerve sheath.

Abstract
OBJECTIVE To investigate the safety and efficacy of topical anesthesia combined with subconjunctival anesthesia (termed two-step anesthesia) for 23- or 25-gauge pars plana vitrectomy or other posterior segment surgery. METHODS Patients (n = 90) requiring 23-/25-gauge vitrectomy or other posterior segment surgery were randomized into 3 groups. Group 1 received peribulbar anesthesia, group 2 received retrobulbar anesthesia and group 3 received two-step anesthesia. A 5-point visual analog pain scale (VAPS) was used to measure self-report of patient pain. Complications were recorded for subsequent analysis. RESULTS VAPS scores for overall intraoperative pain ranged from 0 to 3 (1.07 ± 1.07) in group 1, from 0 to 2 (0.69 ± 0.93) in group 2 and from 0 to 3 (1.06 ± 0.98) in group 3. Assessment of surgeon discomfort score ranged from 0 to 2 (0.31 ± 0.66) in group 1, from 0 to 3 (0.38 ± 0.82) in group 2 and from 0 to 2 (0.47 ± 0.62) in group 3. Both scores reveal no significant difference among the 3 groups. While there were no complications noted in group 1, there was an ocular perforation in group 2. Additionally, there were no complications in group 3 related to the anesthetic technique. CONCLUSIONS Results suggest that two-step anesthesia is a safe and effective anesthetic approach for selected patients undergoing 23- or 25-gauge pars plana vitrectomy or other posterior segment surgeries. It may offer a viable alternative to peribulbar anesthesia and retrobulbar anesthesia for carefully selected 23- or 25-gauge cannular-access ocular surgeries.

Abstract
Purpose The purpose of this study was to evaluate the feasibility and safety of office-based vitreoretinal procedures. Methods Patients undergoing primary elective pars plana vitrectomy were elected for surgery in an office-based setting (performed in a minor procedure room under topical anesthesia [TA] and oral anxiolysis). Rates of surgical objective achievement, surgical timing, and comfort were recorded to evaluate feasibility. Intraoperative and postoperative adverse events were assessed to evaluate safety. Results Office-based vitrectomy surgery was performed in 34 eyes of 30 patients. The mean surgical time was 12.351 ± 8.21 min. Surgical objectives were achieved in 100% of cases. The mean best-corrected visual acuity improvement was 9.08 letters (P < 0.0001). During most parts of the procedure, no patient reported pain or discomfort. Neither intraoperative nor postoperative adverse events were reported until the final follow-up visit. Conclusion Office-based vitreoretinal procedures under TA could be as feasible and as safe as vitreoretinal procedures under conventional anesthesia.

Abstract
Background To compare the safety and efficacy of topical anesthesia versus retrobulbar anesthesia in 27-gauge pars plana vitrectomy (PPV) for vitreous floaters. Methods 30 patients with vitreous floaters were randomized into Group T (topical anesthesia, proparacaine eye drop) and Group R (retrobulbar anesthesia), and underwent 27-gauge PPV. A 5-point visual analogue pain scale (VAPS) was used to assess patients’ pain experience of anesthesia and surgery procedure (during surgery, 2 h and 1 day after surgery). Results The VAPS of anesthesia procedure was 1.27 ± 0.59 for patients in Group R, while it was all 0 for patients in Group T (p < 0.001). There was no significant difference for VAPS during surgery (Group T: 1.13 ± 0.74, Group R: 0.67 ± 0.62, p = 0.67), 2 h (Group T: 0.80 ± 1.01, Group R: 0.67 ± 0.62, p = 0.67) and 1 day (Group T: 0.20 ± 0.41, Group R: 0.27 ± 0.46, p = 0.68) after surgery between these two groups. Only one patient (6.7%) in Group T required additional topical anesthesia during the surgery. Most of the patients reported the pain experience came from initial trocar insertion in both groups. None of the patients required post operative analgesia in both groups. No intraoperative or postoperative complications were noted in both groups. Conclusion This study suggested that topical anesthesia is a safe and effective anesthetic approach for patients with floaters who underwent 27-gauge PPV.

Abstract
BACKGROUND Vitrectomy surgery is one of the commonest ophthalmic procedures performed across the world. It may be performed using general or local anaesthesia encompassing regional or topical anaesthesia depending on a number of factors, including patient suitability, and patient, surgeon or anaesthetist preference. There have so far been no evidence-based recommendations on the best form of anaesthesia for this intervention. There is no clear collated evidence base as to the best type of anaesthesia to reduce harm, and provide best surgical conditions and optimal outcome for patients. OBJECTIVES To compare local with general anaesthesia for adults undergoing pars plana vitrectomy. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library and the reference lists of updated studies on the 25th of July 2016; MEDLINE via Ovid SP (1972 to July 2016) and Embase via Ovid SP (1972 to July 2016). In addition we searched the metaRegister of Controlled Trials (mRCT), ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) in July 2016. We searched the proceedings of the Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) up to July 2016 for information about other relevant studies.We also searched appropriate databases for ongoing reviews. We did not apply any language restriction. We assessed the search as up-to-date on the 25th of July 2016. SELECTION CRITERIA We planned to include all published randomized controlled trials (RCTs) involving comparison of different modalities of local anaesthesia with general anaesthesia for pars plana vitrectomy. We considered the following different modalities of local anaesthesia: sub-Tenon's anaesthesia, retrobulbar anaesthesia, topical anaesthesia, peribulbar anaesthesia. We planned to include cluster-randomized controlled trials. We excluded quasi-RCT trials. DATA COLLECTION AND ANALYSIS Two review authors conducted independent searches and assessed identified studies for inclusion according to the prespecified selection criteria. Two review authors assessed trial quality and planned to extract the data. MAIN RESULTS We found no eligible studies that met our inclusion criteria and were therefore unable to perform a meta-analysis or conduct a methodological quality assessment. AUTHORS' CONCLUSIONS This systematic review failed to locate relevant clinical evidence to support or refute a pars plana vitrectomy performed with various modalities of local anaesthesia versus general anaesthesia. Good-quality clinical trials are needed to define the role of local versus general anaesthesia for pars plana vitrectomy.

Abstract
Background. To compare the efficacy and safety of topical anesthesia versus retrobulbar anesthesia in 23-gauge vitreoretinal surgery. Materials and Methods. A total of 63 patients scheduled for 23 G posterior vitrectomy without scleral buckling procedures were included in the study. The patients were randomly assigned to receive either topical (Group 1, n = 31) or retrobulbar anesthesia (Group 2, n = 32). Postoperatively, patients were shown a visual analogue pain scale (VAPS) from 1 (no pain or discomfort) to 4 (severe pain or discomfort) to rate the levels of pain. Results. There was more discomfort in patients in Group 2 while anesthetic was administered (Group 1: 1.0 ± 0, Group 2: 2.3 ± 0.7, P = 0.0001). Between the two groups the level of pain during surgery (Group 1: 1.4 ± 0.5, Group 2: 1.5 ± 0.5; P = 0.85) was noted. There was also no significant difference between two groups postoperatively (Group 1: 1.2 ± 0.4, Group 2: 1.3 ± 0.4; P = 0.28). There were no complications in either group related to the anesthetic technique. No patient needed sedation or anesthesia supplement during the surgery or postoperative period. Conclusion. Topical anesthesia in posterior vitrectomy procedures is an effective and safe method that is alternative to retrobulbar anesthesia.
