NCT04301817 | Unknown DMC

• 1 other identifier: 20200305
• Study Type: observational
• Target: 50
• Locations: 0 countries

Brief Summary

Long standing prone position could affect vision or optic nerve. To measure the optic nerve sheath diameter using ultrasound is quick and useful assessments of patients. This study will look at the change of optic nerve sheath diameters of patients undergoing surgery in prone position

Conditions

Optic Nerve Sheath Diameter

Outcome Measures

Primary Outcomes (1)

• Change optic nerve sheath diameter

  Change in Optic nerve sheathe diameter from baseline, before surgery, immediate after surgery (prone, supine), 1,3,6,24 and 48 hours after completion of surgery

  0,1,3,6,24 and 48 hours

Study Arms (1)
