Postoperative Delirium After Colorectal Surgery In Older Adults

1101 words - 4 pages

The geriatric population has a greater incidence of postoperative delirium as compared to the rest of the general population. This paper will be a summation of the article submitted this year in the American Journal of Critical Care, Postoperative Delirium after Colorectal Surgery in Older Adults (Mangnall, Gallagher, & Stein-Parbury, 2011) in which postoperative delirium was evaluated by nursing researchers on patients 50 years of age and greater.
Background
This study was done at Sydney Adventist Hospital, Sydney Australia and explored the issues of patients greater than 50 years of age for exhibited symptoms of postoperative delirium after major colorectal surgery. Delirium is associated with greater levels of aversive outcomes and increased costs. It is a causative factor for an increased incidence of self- harm, unplanned
removal of invasive catheters and even permanent mental impairment Postoperative delirium is an acute confusional state manifesting as “a rapid onset, fluctuating course, with cognitive features of inattention, disorganized thinking, and an altered level of consciousness” (Mangall, Gallagher, & Stein-Parbury, 2011, p. 46). The purpose of the study was to clarify if the prevalence and predictors of postoperative delirium in patients undergoing major colorectal surgery was greater in the 50 and greater population. The objective of the study was to determine the degree of prevalence of delirium in those 50 and older along with determining predictors of those more susceptible to postoperative deliriums after major colorectal surgery. This study ultimately affects nursing by increasing their cognitive ability to assess patients that have a higher risk of acquiring postoperative delirium and taking the steps to alleviate or decrease those risks preoperatively and postoperatively.
Methods
This was done as a quantitative study using a prospective, descriptive design.
The patients that were chosen for the study were from a group that were having an elective procedure, 50 years old or greater in age, and able to read and comprehend English. Those that had any mental dysfunction or drug abuse were excluded. Consent to be included in the study was obtained prior to surgery. The study was approved by both the hospital and university human research ethics committees, which operate under the auspices of the National Health and Medical Research Council of Australia. Guidelines followed in the approval process are in keeping with the Helsinki Declaration of 1975 and the revision of 2000.
Of the initial 177 eligible possibilities a final population of 118 males and females greater than 50 years of age were accepted. 59 were excluded for variable problems after they made the initial list of eligibility. There were 54% women, 46% men, mean age was 71.81, and 64% were married. The researches then assessed these patients using the Confusion Assessment Method, an algorithmic tool, otherwise known as CAM for 72 hours post surgically. ...
