High incidence of recess formation at myopectineal orifice during laparoscopic surgery

Background: Post-operative nausea and vomiting (PONV) is quite associated with laparoscopic surgery. In-spite of advances in surgery and post surgical care, nausea and vomiting still has a high incidence. This study was planned to explore the efcacy of a combination therapy of ondansetron with dexamethasone against PONVand compare the results with the efcacy of ondensetron-only. Method:Arandomized clinical trial study was conducted in the Department of Anesthesia, GMC Jammu, over a period of 6 months, on 50 patients in the age group of 18-50 years, of either gender, undergoing laparoscopic surgeries under general anesthesia. Patients were divided into two groups of 25 each: Group A received 4 mg of Ondansetron intravenously, while Group B received 4 mg of Ondansetron and 8 mg of Dexamethasone intravenously, soon after intubation. Results: The demographic variables of two groups were similar. While 19 (76%) patients showed post-operative nausea in Group A, while in Group B, only 8 (32%) patients experienced nausea, which was very signicant. Similarly, 11 (44%) patients showed post-operative vomiting in GroupAand only 2 (8%) complained of vomiting. 24% patients did not complain about any kind of nausea or vomiting in GroupA. Mild nausea was observedin60%patientsinGroupA,while amongonly32%patientsingroupB.Nocomplications of anykindwereobservedduringthisstudy. Conclusion: Ondensetron and dexamethasone, administered intravenously, after intubation, in laparoscopic surgery, is safe and has a better patient response in preventing post-operative nausea and vomiting.

The crystalline perfection of bulk CdTe substrates plays an important role in their use in infrared device technology. The application of chemical etchants to determine crystal polarity or the density and distribution of crystallographic defects in (100) CdTe is not well understood. The lack of data on (100) CdTe surfaces is a result of the apparent difficulty in growing (100) CdTe single crystal substrates which is caused by a high incidence of twinning. Many etchants have been reported to predict polarity on one or both (111) CdTe planes but are considered to be unsuitable as defect etchants. An etchant reported recently has been considered to be a true defect etchant for CdTe, MCT and CdZnTe substrates. This etchant has been reported to reveal crystalline defects such as dislocations, grain boundaries and inclusions in (110) and (111) CdTe. In this study the effect of this new etchant on (100) CdTe surfaces is investigated.The single crystals used in this study were (100) CdTe as-cut slices (1mm thickness) from Bridgman-grown ingots.
