Bedside Ultrasonographic Assessment of the Optic Nerve Sheath Diameter to Assess Intracranial Pressure in Patients Given Ketamine in Emergency Department

Background: There is an ongoing debate if ketamine exerts any effect on intracranial pressure (ICP). ICP can be evaluated noninvasively by means of optic nerve sheath diameter (ONSD) measurement. In the present study, we aimed to determine has perceivable using ONSD.
 Material and Methods: this single-center observational prospectively enrolled patients who were admitted ED received intravenous for induction, analgesia, procedural sedation procedure (ie, fracture reduction, laceration repair, pacemaker implantation). ONSD was used rate changes both before after application.
 Results: a total 75 with mean age 59.8 ± 20.5 years. The majority applied Procedural Sedation (53.3%). administered median 5.10 (IQR: 1) mm 5.00 1.30) mm, respectively. occurred no significant change (p=0.832). 3.70 0.40) 3.65 0.23) prior procedure, (p=0.549). sedation, 4.05 (IQR:0.67) 3.97 0.69) This time, however, significantly reduced administration (p=0.001).
 Conclusions: patient population, did not cause incremental ONSD, surrogate marker ICP.
