Various techniques are applied to reduce the severity of postoperative pain and discomfort in patients. The purpose of this research work was to evaluate the effectiveness and safety of Dexmedetomidine as an adjuvant of anesthesia in ophthalmic surgery. The study included 80 patients who underwent  corneal transplantation on the basis of Dnepropetrovsk Regional Clinical Ophthalmologic Hospital. Patients were divided into 2 groups: control (group K) – 30 men and main (group D) – 50 ones. Multicomponent balanced anesthesia was applied in both groups. Sibazone was administered as the sedative medicine in the group K, Dexmedetomedin was administered in the group D. The main criteria for evaluating the research results were hallmarked: hemodynamic stability during surgery, the amount of administered opiates, the severity of intraoperative pain syndrome by evaluating the ANI index (ANI – analgesia nociception index), the severity of postoperative pain syndrome and the frequency of postoperative nausea and vomiting (PONV). Both schemes of anesthesia allowed avoiding pronounced fluctuations in hemodynamic parameters and gas exchange at all stages of the study. Analyzing the severity of intraoperative pain, we found that in group K pain relief could be considered insufficient during the first 7 minutes of the most traumatic stage of the surgery, while in group D the ANI index did not fall below 50. Statistically significant differences were obtained on minute 1, 2, 5, 6, and 7 of the surgery. The number of episodes of insufficient anesthesia during the most traumatic stage of the surgery in group K was statistically significantly higher than in group D. Analyzing the quality of pain relief in the postoperative period it was determined, that the level of pain on the Visual Analog Scale (VAS) after awakening in both groups was equal to 0. At the next three stages of the study (2 hours, 6 hours after surgery, and the next morning), the level of pain in group K was significantly higher than in group D. In addition, it was determined that the need for narcotic analgesics and the number of episodes of postoperative nausea and vomiting in group K was statistically significantly higher than in group D. These given data allow us to conclude that Dexmedetomedin is the effective adjuvant of the anesthesia for corneal transplantation.

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.

Background. Despite the significant development of modern anesthesiology, the pain relief of surgical patients is still unsatisfactory. Inadequate pain management causes psychological discomfort and complications. The combination of general anesthesia with various options for local anesthesia allows one to get closer to solving the problem of pain. The aim of the study was to compare the effect of multicomponent balanced anesthesia (intravenous + inhalation) and multicomponent balanced anesthesia, supplemented by pterygopalatine fossa blockade on the safety and efficacy of anesthesia for corneal transplantation. Materials and methods. The study included 73 patients, divided into two groups. Group С received multicomponent balanced anesthesia, group B — pterygopalatine fossa blockade additionally. The main criteria for evaluating the results of the study were: stability of hemodynamics and gas exchange during surgery, the severity of intraoperative pain syndrome by recording the analgesia nociception index, the severity of postoperative pain syndrome and the incidence of postoperative nausea and vomiting. Results. Both schemes of anesthetic management made it possible to avoid pronounced fluctuations in hemodynamic and gas exchange parameters at all stages of the study. Analyzing the severity of intraoperative pain, we found that in group С, pain relief could be considered insufficient during the first 7 minutes of the most traumatic stage of the operation, while in group B the analgesia nociception index did not decrease below 50. Statistically significant differences were obtained during 8 out of 10 minutes of the stage. Analysis of the pain relief quality in the postoperative period has shown that the level of pain according to the visual analogue scale upon awakening was equal to 0 in both groups, at the next three stages of the study (two and six hours after surgery and on the morning of the next day) the level pain in group C was significantly higher than in group B. Conclusions. The addition of regional blockade to multicomponent general anesthesia allows for adequate control of postoperative pain without compromising the safety profile.

Objective:To evaluate the efficacy of Metoclopramide versus Dexamethasone for prevention of postoperative nausea and vomiting during general anesthesia. Study Design:This is a Randomized control trial (RCT) study. Setting: Study carried out at Department of Anaesthesiology, Surgical Intensive Care Unit and Pain Management, Clinic, Dow University of Health Sciences and  Dr. Ruth Pfau  Hospital Karachi, from December 2018 to June 2019. Materials and Methods:110 patients undergoing elective surgeries, who fulfilled the inclusion criteria and gave informed consent were included in the study. They were randomly assigned to either group M or group D, with 55 patients in each group. All patients were then administered either intravenous dexamethasone (8mg) in group D or intravenous metoclopramide (10mg) in group M at the time of induction of anesthesia. The main outcome measure was postoperative nausea and vomiting, at the end of 6th hour postoperatively. The SPSS version 21 was applied to the data. Results: Majority of the patients 66 (60%) were of age 35 years or less. Mean age of the patients was 35.09±11.55 years. There were more females than males, with male to female ratio being 1:1.03. Overall, in patients receiving metoclopramide, 12(21.8%)  had postoperative nausea and vomiting, while in patients who received dexamethasone, only 4 (7.3%) patients had post-operative nausea and vomiting. When comparing two groups, there was statistically significant (p= 0.02) reduced postoperative nausea/vomiting among those patients who had received intravenous dexamethasone. Conclusion: Intravenous dexamethasone is more effective than Metoclopramide in preventing postoperative nausea and vomiting in patients during general anesthesia.

Postoperative nausea and vomiting (PONV) after vitreoretinal surgery may potentially be associated with severe complications, such as suprachoroidal hemorrhage. The purpose of the present multicenter clinical trial (NCT02386059) was to assess the efficacy of three different prophylactic treatments for PONV after vitrectomy under local anesthesia. Patients undergoing primary vitrectomy were randomized to the control arm or to one of the treatment arms (4 mg ondansetron, 4 mg dexamethasone, combination of the two drugs). The primary outcome measure was the proportion of complete response (no nausea, no vomiting, no retching, and no use of antiemetic rescue medication) during 24 h after vitrectomy. Secondary outcomes included the severity standardized score of PONV, postoperative pain standardized score, and rate of ocular and non-ocular adverse events. Baseline demographics of the 1287 patients were comparable between the four arms. The combined therapy group showed a statistically significant lower incidence of PONV compared to the placebo and monotherapy (p < 0.001). PONV severity was also reduced in the combination group compared to the others (p < 0.001). Postoperative pain scores and adverse events were comparable among the four groups. Combined therapy with dexamethasone and ondansetron was the most effective treatment for reducing the incidence and severity of PONV in patients undergoing vitrectomy under local anesthesia.

Materials and methods. The study included 20 patients aged 25 to 84, 11 men and 9 women with various front eye pathologies. 10 patients were anesthetized according to the classic scheme taken in our clinic. In the other 10 patients, the pain relief scheme was supplemented by the implementation of pterygopalatine fossa block. Monitoring during the operation included non-invasive monitoring of hemodynamics, pulsoxymetry, determination of oxygen and carbon dioxide concentration in exhaled air. In postoperative period level of pain was fixed using visual-analogue scale and frequency of postoperative nausea and vomiting. Results. The study found that patients in the groups had no statistically significant differences in sex, age and severity of surgery. At all stages of the study, the severity of pain in patients with the pterygopalatine fossa block was reliably lower than in patients in the control group. The incidence of postoperative nausea and vomiting was also lower in the blockade group.

Background: Postoperative nausea and vomiting (PONV) is an undesirable outcome that parturient who undergo caesarean section experience. We compare the efficacies of IV glycopyrrolate and IV dexamethasone as prophyaxis against PONV in these paturient.Methods: This was a prospective, randomized, double blind placebo-controlled study of seventy six (76) ASA II patients aged 18-40 years who underwent elective caesarean section under spinal anaesthesia. Patients were randomly allocated to three groups, group G (glycopyrrolate): n=26, group D (dexamethasone): n=25 and group C (control; normal saline): n=25. Data collection was with the aid of a proforma which included the biophysical profile, Belville scoring scale for PONV, Likert scale was used for patient satisfaction and side effects were also documented. The data were analyzed using SPSS version 17 and presented in tables and figures.Results: The demographic characteristics and mallampati scores of patients in all 3 groups were similar. The results showed that the incidence of PONV in group D was 8%, in group G 19.2% and in group C 32% (p= 0.048, OR= 0.185, 95% C.I for OR= 0.035 – 0.983). All patients expressed satisfaction in the care they received as assessed using the Likert scale and only patients who received IV glycopyrrolate experienced side effects in the form of dryness of the mouth. There were no side effects reported in patients who received IV dexamethasone.Conclusions: The study demonstrated that IV dexamethasone 8mg was more effective in controlling PONV after intrathecal fentanyl and bupivacaine for caesarean section when compared to 0.2 mg IV glycopyrrolate.

Background: On thyroidectomy, incidence of postoperative nausea and vomiting, severe pain with local inflammation and voice impairment was very common. These effects can be manipulated by the use of steroids. Hence the present study, was conducted with the objective to evaluate the effects of a single preoperative dose of dexamethasone on thyroidectomy in terms of postoperative nausea and vomiting (PONV), pain and voice improvement.Methods: The present study was conducted between October 2010 and March 2011 at the Department of General Surgery, Government Medical College, Kottayam, Kerala, India. A total of 72 patients were included in the study after meeting requirements of inclusion criteria. They were divided into two groups. 37 were under Group C and received normal saline and remaining 35 served as Group D and received 8 mg/2 mL of dexamethasone preoperatively. Post-operative incidences of nausea and vomiting, pain scores, and the improvement of vocal function were compared in both groups.Results: Out of 72 patients, most of the patients participated were under the age group of 40-50 years (30.6%). Of them 9 were males and 63 were females. The incidence and severity of PONV and pain was significantly reduced in Group D compared to Group C with P values of 0.001 and 0.056 respectively. Significant protection of dexamethasone towards vocal function was not observed in the study (p =0.245).Conclusions: From the results obtained in the study, it was concluded that preoperative single dose administration of dexamethasone seemed to be safe in healthy patients undergoing thyroidectomy.
