BackgroundShort acting inhalational anesthetic (Desflurane) produces emergence agitation (EA) in pediatrics with an incidence up to 80%. The aim of the present study was to examine the role of Gabapentin oral solution in attenuating desflurane associated EA in children after strabismus surgery under general anesthesia.MethodsSeventy patients, 2–6 years old, scheduled for strabismus surgery were randomly allocated into two groups (35 each); Control group (c): received 5 ml of oral strawberry juice (placebo) and Gabapentin group (G) received 5 mg/Kg gabapentin oral solution in 5 ml strawberry juice, 1 h before anesthesia. Patient separation, cooperation, emergence incidence and emergence severity were assessed. Also time to extubation and time to emergence, duration of PACU stay, PONV and number of patients required meperidine postoperatively were recorded.ResultsDuration to extubation and duration to emergence were statistically prolonged in gabapentin group compared to the control group. The incidence of EA and its severity were reduced in gabapentin group with more tendencies to be asleep and less attentive. More patients in the control group required postoperative meperidine to reduce crying and agitation.ConclusionOral gabapentin 5 mg/kg reduced the incidence and severity scoring of emergence agitation (by 20%) with more tendencies for sleeping with preserved response to stimuli in PACU.Trial registrationNumber: NCT03347916, date: November 17, 2017, retrospectively.

Purpose: The previous reports tried to reduce shivering and improve neuraxial anesthesia characteristics by the systemic use of different drugs. This study was directed to evaluate the effect of pregabalin premedication on both shivering and epidural characteristics following single shot loading. Patients and Methods: Eighty female patients, ASA grade I and II, scheduled for gynecological surgeries under epidural anesthesia were studied. The patients were divided into two groups: Pregabalin (P) group and Control (C) group in which the patients received 150 mg of pregabalin and placebo capsules respectively sixty minutes prior to surgery. Following epidural loading, the onset and degree of shivering were compared between the two groups. Also, the epidural onset, level and duration were compared. The perioperative hemodynamics, sedation scores, meperidine consumption and side effects were followed up and registered. Results: The onset of shivering was significantly prolonged and the degree of shivering was less in pregabalin group compared to Control group. The duration of epidural shot was shorter in the control group in relation to the pregabalin treated patients. Regarding both onset and level of block, no significant changes were detected. The patients were more sedated with less meperidine consumption in the pregabalin group. The two groups were similar as regards the perioperative hemodynamics and occurrence of side effect. Conclusion: The premedication with pregabalin reduced onset and degree of shivering and prolonged the duration of single shot epidural block.

In the current study, the performance of superabsorbent hydrogel composites comprised of Guar gum-Pectin/ Polyacrylamide/ ZnO crosslinked with gamma irradiation (10 kGy) has been investigated for sustainable agriculture. The claimed composites (GG/PC/PAAm/ZnOx) were characterized by FTIR, TGA, and AFM. The swelling capacity data reveal that the equilibrium water swelling (EW) of the composites was increased by increasing the ZnO content from 600 g/g to 1050 g/g for zero to the highest concentration of ZnO, respectively. Furthermore, the physical properties of the soil mixed with the hydrogels were improved; water holding capacity (WHC) increased to 66% and water retention (WR) kept at 15% after 20 days. The composites showed a good degradability in the biodegradation test. They also portrayed super-absorption capacity at three swelling/deswelling cycles. This advancement is important for reducing water consumption through the irrigation of arid lands. The prepared composites were proved as excellent candidates in sustainable agriculture applications.
