Effects of Low-Dose Ketamine Infusion on Alleviating the Opioid Burden for Patients Undergoing Myomectomy Surgery.

Objective: Recent research has focused on the use of N-methyl-D-aspartate (NMDA) receptor antagonists for pain management. Several drugs are known to have this action, including ketamine, which exerts its main analgesic effect through NMDA receptor antagonism. This study aimed to evaluate the effect of low-dose ketamine infusion on opioid exposure for patients undergoing myomectomy surgery under general anaesthesia.

Epidural levobupivacaine versus a combination of levobupivacaine and dexamethasone in patients receiving epidural analgesia.

Background And Aims: The use of dexamethasone as an adjuvant to local anesthetic rarely has been described. Some studies have demonstrated the analgesic effect of local spinal and systemic corticosteroids in combination with bupivacaine. It works by decreasing inflammation and blocking transmission of nociceptive C-fibers and by stopping the ectopic discharge of the nerve.

Evaluation of gastric residual volume in fasting diabetic patients using gastric ultrasound.

Background: Diabetic patients are claimed to have high risk of delayed gastric emptying; however, the evidence concerning residual gastric volume in fasting diabetic patients is not consistent. The aim of this work is to evaluate residual gastric volume in fasting diabetic patients for elective surgery.

Methods: Fifty patients scheduled for elective surgery under general anaesthesia were included in the study.

Toxicological studies for some agricultural waste extracts on mosquito larvae and experimental animals.

Objective: To evaluate some agricultural waste extracts as insecticide and their effects on enzyme activities in liver and kidney of male mice.

Methods: The insecticidal activity of five tested compounds (one crude extract and 4 waste compounds) was bioassay against the 3rd instars of the Culex pipiens (Cx. pipiens) larvae in the laboratory.

Ultrastructure of normal and JHA-treated eggs of the soft tick Argas persicus (Oken).

The ultrastructure of normal development and JHA-treated egg was examined with the transmission electron microscope. In newly oviposited egg, the chorion consists of exo- and endochorion. Between the chorion and plasma membrane lies vitelline (envelope) membrane, a thin non cellular membrane.
