Limited literature exists on the vascular reactivity of the radial and ulnar arteries in hypertensive patients following radial artery cannulation. This study assessed the vascular reactivity of the radial and ulnar arteries by comparing Doppler images and laser speckle contrast imaging (LSCI) obtained from both normotensive and hypertensive patients after radial artery cannulation under general anesthesia. ⋯ The radial and ulnar arteries in hypertensive patients may lack a compensatory response to radial artery cannulation during general anesthesia.

Observational Study
The influence of anesthetic drug strategy on the incidence of post induction hypotension in elective, non-cardiac surgery - A prospective observational cohort study.
To identify the influence of modifiable factors in anesthesia induction strategy on post-induction hypotension (PIH), specifically the type, dosage and speed of administration of induction agents. A secondary aim was to identify patient related non-modifiable factors associated with PIH. ⋯ This study was registered in the Dutch Medical Research in Humans (OMON) register on 18 June 2019 (ID: NL7810). The study was approved by the Medical Ethics Committee of the Amsterdam UMC, location AMC, the Netherlands in December 2018 (NL 6748.018.18; 2018).

Masseter spasm after induction of anaesthesia can be generally defined as a marked difficulty in manual mouth opening that interferes and impedes direct laryngoscopy and tracheal intubation without the presence of temporomandibular joint dysfunction. Several factors have been implicated in the literatures responsible for causing masseter spasm including use of non-depolarizing muscle relaxants, selective serotonin reuptake inhibitor and anxiety. ⋯ Anaesthesiologist should be aware of this complication when dealing with anxious patients on antidepressant therapy during induction of anaesthesia. Masseter spasm with locked jaw, can be a potential life-threatening situation particularly in scenarios of "cannot- ventilate-cannot intubate".

Postoperative delirium is a common neurological complication, especially in older patients undergoing surgery, which is closely related to the poor prognosis of patients. The objective was to investigate the effects of esketamine on postoperative delirium in patients with general anesthesia. ⋯ According to our meta-analysis, the use of esketamine during anesthesia induction significantly reduced the incidence of postoperative delirium in patients undergoing elective general anesthesia without increasing the incidence of postoperative adverse reactions.

The optimal type of anesthesia for reducing postoperative delirium remains undetermined. This study aimed to assess the relationship between type of anesthesia and postoperative delirium. ⋯ Compared to general anesthesia, regional anesthesia was associated with a decreased incidence of postoperative delirium in patients who underwent total hip or total knee arthroplasty. Our findings indicate that avoiding general anesthesia may prevent delirium after lower limb surgery.
