Children ages 13 or older scheduled to receive proton radiation therapy were included in the study.
Subjects watched the virtual reality tour of the radiation therapy facility with a child life therapist experienced in coaching children receiving radiation therapy and completed a survey after the tour.
Eight subjects consented for participation and 6 completed the virtual reality tour. All of the enrolled patients completed the virtual reality tour successfully.
Two subjects did not complete the survey. Two subjects requested to pause the tour to ask questions about the facility. Five subjects said the virtual reality tour was helpful preparation before undergo proton radiation therapy. None of the subjects experienced nausea or vomiting. The virtual reality video tour allowed patients to explore the treatment facility in a comfortable environment.
Participants expressed that the tour was beneficial and would appreciate seeing other parts of the hospital in this way. Jun 4, Open Peer Review Period: Jun 6, - Aug 1, This manuscript needs more reviewers Background: Postoperative cognitive decline POCD is defined as a new cognitive impairment arising after surgical intervention.
Aspects of cognitive function can be assessed using various validated c Aspects of cognitive function can be assessed using various validated cognitive function tests including: There is some concern that prolonged Trendelenburg positioning during laparoscopic colorectal surgery may cause POCD. To assess the effect of the time spent in Trendelenburg position on cognitive function. Volunteers were placed in Trendelenburg for 3 hours, then supine for 30 minutes.
Validated cognitive function tests including: Fifteen healthy volunteers were recruited 8 male, 7 female , average age of 69 years range: Accuracy remained within 2 SDs at all time-points. When moved supine, The results of this study indicate that Trendelenburg positioning appears to lead to cognitive decline. This may have implications for patients undergoing prolonged Trendelenburg positioning in laparoscopic colorectal surgery.
Jun 4, - Jul 30, Background: The incidence of perioperative visual loss following colorectal surgery is quoted as 1. Raised IOP during extreme Trendelenburg position leading to reduced optic nerve Raised IOP during extreme Trendelenburg position leading to reduced optic nerve perfusion is thought to be a cause.
Assess the effect of the degree of Trendelenburg tilt and time spent in Trendelenburg on IOP during laparoscopic colorectal surgery. Fifty patients undergoing laparoscopic colorectal surgery were recruited. A correlation coefficient for the degree of Trendelenburg tilt and IOP was calculated for each patient. Group 1 included patients undergoing a right-sided colonic procedure and Group 2 included all left-sided colonic procedures.
The average length of surgery for Group 1 was The mean maximum degree of Trendelenburg tilt in Group 1 was 9. The mean IOP rise was 9. There is a strong correlation between IOP rises during laparoscopic colorectal surgery and the degree of Trendelenburg tilt.
This may be significant for patients undergoing prolonged surgery and especially those with glaucoma.
