Randomized Controlled TrialComparison of the effect of sevoflurane and propofol on the optic nerve sheath diameter in patients undergoing middle ear surgery.
During middle ear surgery, the patient's head is turned away from the surgical site, which may increase the intracranial pressure. Anesthetics also affect the intracranial pressure. The optic nerve sheath diameter (ONSD) measured using ultrasonography is a reliable marker for estimating the intracranial pressure. This aim of this study was to investigate the effect of sevoflurane and propofol on the ONSD in patients undergoing middle ear surgery. ⋯ The ONSD was significantly increased during middle ear surgery. No significant difference was observed in the amount of ONSD increase between the sevoflurane and propofol groups.

Identification of interfascial plane using injection pressure monitoring at the needle tip during ultrasound-guided TAP block in cadavers.
Consistency in needle tip positioning within interfascial planes while performing infiltrative blocks under ultrasound guidance can be difficult. The exact determination of such planes may beyond the physical limits of common ultrasound machines. Aim of this pilot study was to understand if real-time continuous injection pressure monitoring at the needle tip, combined with ultrasound guidance, can help to immediately and consistently identify an interfascial plane needle tip placement. ⋯ The identified injection pressure pattern, together with ultrasound image, may help in determine real-time the needle tip position, while performing a TAP block.

Anesthetic management for emergency cesarean section in a patient with status epilepticus: A case report.
The presence of clinically significant repeated maternal epilepsies during pregnancy increases the risk of adverse maternal, fetal and neonatal outcomes. However, there are few guidelines for anesthesiologists to deal with this situation. ⋯ Providing anesthesia to patients undergoing cesarean section poses major challenges for anesthesiologists. Close monitoring and proper treatment can help reduce risks for both the mother and baby.

Cancer is a growing global burden; there were an estimated 18 million new cancer diagnoses worldwide in 2020. Excisional surgery remains one of the main treatments for solid organ tumours in cancer patients and is potentially curative. ⋯ However, it has been hypothesised that anaesthetic and analgesic techniques during surgery might influence the risk of cancer recurrence. This narrative review aims to provide an updated summary of recent observational studies and new randomised controlled clinical trials on whether certain specific anaesthetic and analgesic techniques or perioperative interventions during tumour resection surgery of curative intent materially affect long-term oncologic outcomes.
