Efficacy Of Pethidine And Tramadol In The Suppression Of Postoperative Shivering: A Comparative Study, Ahmed Jaber Ibrahim, Hussien Ibrahim Hayal, Ahmed R.Y. Al-Sawad, Shahab Abdulla, Ralela Makline

AUIQ Complementary Biological System

Postoperative shivering is a common complication that can affect patient comfort and stability. Pethidine and tramadol are widely used to relieve this symptom, but their relative effectiveness and safety remain under investigation. In this randomized trial, 50 patients (aged 25–35 years) with postoperative shivering were divided into two groups: one group receiving intravenous tramadol (n = 25 patients) and one group receiving pethidine (n = 25 patients). Onset of drug action, vital signs, and side effects were systematically assessed. Pethidine had a significantly faster onset of action than tramadol (12.20 ± 0.35 min vs 7.16 ± 0.28 min, p < 0.001). No significant differences were observed between the two groups regarding body temperature, heart rate, oxygen saturation, or blood pressure (P < 0.05). Side effects, such as dizziness (16% vs. 8%), nausea and vomiting (20% vs. 8%), and nausea alone (48% vs. 20%), were more common and showed a statistically significant increase in the tramadol group. Both drugs were effective in suppressing postoperative tremor, but pethidine demonstrated superior efficacy, a faster onset of action, and a better safety profile. These results confirm pethidine as the recommended choice at an intravenous dose of 0.5 mg/kg.

AUIQ Complementary Biological System

This work investigates the efficacy of fenugreek seed powder (FSP), an agricultural product, as an economical and sustainable biosorbent for the extraction of crystal violet (CV) dye from aqueous environments. The biosorbent was analyzed using XRD, FTIR, and SEM-EDX, validating its amorphous structure, surface functional groups, and porous shape. Batch biosorption tests were adjusted utilizing a Box–Behnken design (BBD), incorporating three independent variables: FSP dose (0.02–0.1 g/100 mL), pH (4–10), and time (5–60 min). The model exhibited exceptional prediction accuracy (R² = 0.99, CV = 2.12%) and recognized all three variables as statistically significant (p < 0.05). The maximum CV removal attained was 91.8% efficiency at an FSP dose of 0.1 g/100 mL, pH 7, and a time of 60 minutes. FTIR examination indicated changes in the –OH, C=O, and C–O functional groups, signifying their participation in dye interaction, whilst SEM pictures validated dye deposition on the biosorbent surface. The biosorption process was ascribed to electrostatic forces, hydrogen bonding, π–π stacking, and pore filling. These findings underscore FSP as a viable, economical biosorbent for the removal of cationic dyes in wastewater treatment applications.
