Abstract Background: Despite of the risk of postoperative intolerable pain perception (PIPP), vitreoretinal surgery (VRS) requires general anaesthesia (GA) in selected patients. Intraoperative use of opioid analgesics (OA) during GA carries the risk of postoperative nausea and vomiting (PONV). The surgical pleth index (SPI) optimises the intraoperative titration of OA. Regional anaesthesia techniques are combined with GA to minimize the intraoperative use of OA. We evaluated the benefit of preventive analgesia techniques combined with GA using SPI-guided fentanyl (FNT) administration on the incidence of PONV, oculocardiac reflex (OCR) and PIPP in patients undergoing VRS. Methods: One hundred and five patients undergoing VRS were randomly allocated to receive either GA with SPI-guided fentanyl (FNT) administration alone (GA group) or with preventive topical 2% proparacaine (topical anaesthesia (TA) group) or preoperative peribulbar block (PBB) using 0.5% bupivacaine with 2% lidocaine (PBB group). Fifteen patients were excluded due to problems with postoperative SPI measurement. Results: Preventive PBB resulted in intraoperative reduction in FNT requirement, with no influence on perioperative outcomes. Intraoperative SPI-guided FNT administration during GA resulted in OCR in 7.78%, PONV in 10% and PIPP in 13.5% of patients undergoing VRS. Intraoperative SPI-guided FNT administration blunted the perioperative effect of preventive PBB and TA in terms of the presence of PONV, OCR and PIPP.Conclusions: The utility of SPI-guided FNT administration during GA eliminated benefits of preventive analgesia with PBB and TA following VRS. We recommend using intraoperative SPI-guided FNT administration during GA to reduce the presence of OCR, PONV and PIPP following VRS. Trial registration: The trial was approved and registered by The Ethical Committee of Medical University of Silesia on 29th of September 2015, as well as the project was registered in the Clinical Trial Registry (SilesianMUKOAiIT2, NCT02973581)Key words: vitreoretineal surgery, general anaesthesia, peribulbar block, topical anaesthesia, surgical pleth index.

Purpose: To date, no protocol of anesthesia for pediatric ophthalmic surgery is unanimously recognized. The primary anesthetic risks are associated with strabismus surgery, including oculocardiac reflex, postoperative nausea and vomiting, and postoperative pain. Methods: This was a prospective, monocentric, observational study conducted in a tertiary pediatric ophthalmic unit. Our anesthetic protocol for strabismus surgery included postoperative nausea and vomiting prevention using dexamethasone and ondansetron. No drug-based prevention of oculocardiac reflex or local/locoregional anesthesia was employed. Results: A total of 106 pediatric ophthalmic surgeries completed between November 2015 and May 2016 were analyzed. The mean patient age was 4.4 (range: 0.2–7.3, standard deviation: 2.4) years. Ambulatory rate was 90%. Oculocardiac reflex incidence was 65% during strabismus surgery (34/52), 50% during congenital cataract surgery (4/8), 33% during intramuscular injection of botulinum toxin (1/3), and 0% during other procedures. No asystole occurred. Postoperative nausea and vomiting incidence was 9.6% after strabismus surgery (5/52) and 0% following the other procedures. One child was hospitalized for one night because of persistent postoperative nausea and vomiting. Postoperative pain generally occurred early on in the recovery room and was quickly controlled. Its incidence was higher in patients who underwent strabismus surgery (27%) than in those who underwent other procedures (9%). Conclusion: Morbidity associated with ophthalmic pediatric surgery is low and predominantly associated with strabismus surgery. The benefit–risk ratio and cost-effectiveness of oculocardiac reflex prevention should be questioned. Our postoperative nausea and vomiting rate is low, thanks to the use of a well-managed multimodal strategy. Early postoperative pain is usually well-treated but could probably be more effectively prevented.

Aim.Efficacy of granisetron and combination of granisetron and dexamethasone was evaluated for prevention of postoperative nausea and vomiting (PONV) in children undergoing elective strabismus surgery.Methods.A total of 136 children (1–15 years) were included. Children received either granisetron (40 mcg/kg) [group G] or combination of granisetron (40 mcg/kg) and dexamethasone (150 mcg/kg) [group GD]. Intraoperative fentanyl requirement and incidence and severity of oculocardiac reflex were assessed. PONV severity was assessed for first 24 hours and if score was >2, it was treated with metoclopramide. Postoperative analgesia was administered with intravenous fentanyl and ibuprofen.Results.The demographic profile, muscles operated, and fentanyl requirement were comparable. Complete response to PONV in first 24 hours was observed in 75% (51/68) of children in group G and 76.9% (50/65) of children in group GD, which was comparable statistically (p=0.96, Fisher exact test; OR 1.11, 95% CI 0.50, 2.46). Incidence of PONV between 0 and 24 hours was comparable. One child in group G required rescue antiemetic in first 24 hours and none of the children had severe PONV in group GD. There was no significant difference in incidence or severity of oculocardiac reflex.Conclusion.Dexamethasone did not increase efficacy of granisetron for prevention of PONV in elective pediatric strabismus surgery. Registration number of clinical trial wasCTRI/2009/091/001000.

Abstract Background: Postoperative nausea and vomiting (PONV) are common side-effects following strabismus surgery. The present study aimed to compare the effects of different doses of dexmedetomidine (DEX) on PONV incidence in pediatric patients undergoing strabismus surgery. Methods: In this prospective randomized double-blinded study, 126 pediatric patients undergoing strabismus surgery were randomized into one of three groups: Placebo group, normal saline; DEX1 group, 0.3 ug/kg dexmedetomidine, and DEX2 group, 0.5 ug/kg dexmedetomidine. Oculocardiac reflex (OCR) events were recorded during surgery. PONV or postoperative vomiting (POV) was recorded for 24 hours in the ward. Pediatric anesthesia emergence delirium (PAED) scale and emergence agitation (EA) scale were recorded in the recovery room. Results: Intraoperative OCR was significantly reduced in DEX2 group (42%) as compared to that of Placebo group (68%) (p=0.0146). During the first 24 hours post-op, the overall incidence of PONV was significantly lower in DEX2 group (10%) than that of Placebo group (32%) (p=0.0142). There was no significant difference in POV among the three groups. PAED or EA scores among the three groups were similar during recovery time. Conclusion: Dexmedetomidine (0.5 ug/kg) reduced OCR and PONV without lengthening extubation time or recovery time in pediatric patients undergoing strabismus surgery. Trial registration:The trial was prospectively registered before patient enrollment at Chinese Clinical Trial Registry (Clinical Trial Number: ChiCTR1800020176, Date: 12/19/2018). Keywords: Dexmedetomidine, Postoperative nausea and vomiting, Strabismus surgery, Oculocardiac reflex, Emergence agitation

Postoperative nausea and vomiting (PONV) is a major complication in patients who undergo surgery under general anaesthesia. Various drug regimens and antiemetic interventions have been tried from time to time for prevention of PONV but with a variable success rate. The aim of the study is to compare between ondansetron vs Palonocstron for controlling postoperative nausea and vomiting. In this prospective study, 100 patients aged 18-60 years of ASA GRADE-I and II scheduled for undergoing surgery under general anaesthesia after taking informed written consent at a tertiary care hospital, were randomly divided into two groups of 50 each. Group-A was given palonosetron 75 μg and Group-B was given ondansetron 4 mg. At 72 hours, nausea and vomiting were statistically significant between ondansetron and palonosetron groups. Postoperative side-effects such as headache, dizziness and drowsiness were not statistically significant between ondansetron and palonosetron groups. In conclusion, the antiemetic efficacy of palonosetron is similar to that of Ondansetron for preventing PONV during the first 24 hours after patients who undergo surgery under general anaesthesia. But after 72 hours, nausea and vomiting were statistically higher in ondansetron group than palonosetron group. CBMJ 2017 July: Vol. 06 No. 02 P: 15-20
