Is actually intensive care needed subsequently after elective abdominal aortic aneurysm repair?

Background: To examine morbidity along with mortality associated with sufferers having the elective, open repair of abdominal aortic aneurysms and were accepted postoperatively to a surgical stepdown unit instead of routinely to the intensive care unit (ICU), we executed a retrospective program review.

Methods: All of men and women going through such type of restoration over a 27-month period of time were reviewed. A successive 230 men and women who have experienced aneurysm repair from September 1999 through November 2001 were routinely accepted to a surgery stepdown unit postoperatively, with only a minority of sufferers which require admittance to ICU. We analyzed the rate of primary ICU admission and that of following ICU admission just after stepdown-unit admission. We at the same time assessed morbidity, death rate and even period of medical center remain for individuals admitted to ICU as well as those admitted to the stepdown unit.

Results: ICU admission was prevented in 204 (89%) of these patients. The remaining TWENTY SIX persons (11%) necessary ICU admission at some point during their hospital remain. Solely Three people (1%) in actual fact admitted to the stepdown unit therefore required postoperative admission to ICU.

Final thoughts: Our experience proves that the right preoperative evaluation and also selection provides the majority of elective infrarenal aneurysm repairs to be risk-free treated postoperatively in a stepdown unit, and that soon after ICU admissions usually are unusual.

Classic elective, open remedy of abdominal aneurysm (AAA) has a documented death level which varies from 4.8% to 8.4%. Due to this huge peri-operative hazard, the majority of sufferers proceeding with elective aortic surgery treatment have been routinely accepted to the intensive care unit (ICU) for the 1st postoperative day (POD) for tracking. For the reason that ICU services become more reduced, growing constraints have been subjected to elective ICU admissions, and also alternatives are being discovered for schedule proper care following AAA repair. Selective utilization of the ICU based on individual patient factors has been documented; direct ad­mission to the surgical ward was found out to be safe and cost-effective in up to 48% in one series of sufferers and 88% in another. To determine practice patterns here in Canada, we surveyed the existing membership of the Canadian Society for Vascular Surgery (CSVS) and found that 33 of 43 respondents (77%) routinely admit their persons to the ICU post-operatively.

In big health-related organisations, postoperative AAA sufferers are regularly ad­mitted to a stepdown unit (SDU) on a surgery ward exactly where patients undergo noninvasive hemodynamic moni­toring by accredited nurse practitioners. Just a minority of individuals are accepted to the ICU, caused by comorbid health concerns as well as person patient factors dictated either pre- or peri-operatively. In this survey we retrospectively analyzed the outcomes associated with schedule admission to the SDU for fatality, major morbidity, time period of stay (LoS) and need pertaining to resultant ICU admission.

Working with our Vascular Registry data files we retrospectively reviewed the consecutive, elective, open AAA repairs executed at a tertiary care referral centre. From September 99 through November 2001, 230 such repairs were done at London Health Sciences Centre, Victoria Campus by 3 vascular surgeons. This particular report comprises just sufferers who experienced standard open, infrarenal AAA remedy where the repair was constructed at or below the renal arteries, regardless of the positioning of the proximal aortic clamp. Persons were not included if they had ruptured aneurysms, a suprarenal component, aorto-bifemoral grafting for occlusive condition or endovascular repairs.

Mean age, comorbid health care complications, risk variables and final results were compared to those of individuals considered suitable for primary postoperative admission to the SDU.

Ahead of the operation, men and women were examined by the medical expert responsi­ble and by internal medicine and anesthesiology consultants in a preadmission clinic. A preoperative verdict was made for postoperative admission either to the SDU or ICU, according to their comorbid healthcare problems.

Individuals primarily admitted to the ICU (n = 23, 10%) were compared with individuals admitted to the SDU (n = 207, 90%). Although the ICU set got more dangerous medical conditions, culminating in their assortment for direct ICU admission, the sets were very similar in age group (mean 72 yr in either group), gender selection percentage as well as overall prevalence associated with risk aspects for example serious CAD, COPD, high blood pressure and even tobacco use.

Overall, 6 study sufferers (2.6%) died.

Verdict

As a consequence of serious perioperative danger as well as connected health care comorbidities, postoperative admission to the ICU has been regular following elec­tive, open, infrarenal AAA remedy. Selective use of the ICU based upon indi­vidual patient factors has been discovered harmless and also cost-effective.

Over-all death rate in this particular series of 230 persons was 2 .6%, that is less than a lot of shared rates from the literary works. The Canadian aneurysm investigation recorded an overall death level of 4.8% for a category of equivalent men and women. The variance may be partly the result of the fact that during this exact same 26-month period of time we executed 99 infrarenal, endovascular aneurysm repairs, an operation currently limited to high-risk clinical persons. Had the surgical procedures been carried out as standard open procedures, the overall fatality rate and ICU admission rates would likely have been greater. Hence, we have indicated that SDU admission is normally trustworthy for the majority of people proceeding with open AAA remedy, without any fatalities in cohort of patients trea­ted postoperatively in the SDU rather than the ICU.

Although ICU admission for the purposes of more intense observation has been traditional subsequent AAA repair, the actual literature does not assist any added benefit from far more intrusive observation having pul­monary-artery catheters.

Not unexpectedly, the fatality rate was substantial in the set originally accepted to the ICU (17%): all these patients preselected for ICU admission were known to be at greater risk. Main health care morbid­ity as well differed between sets; the higher frequency of additional complications can also likely be gained via preselection.

The standard clinic stay for all our study patients, 7. 7 days (standard deviation 4.5 d), approximates statements from the literature.

ICU admission was eliminated for 89% of patients proceeding with elective, open infrarenal AAA repair. Only Three individuals (1%) in the beginning admitted to the SDU therefore required ad­mission to the ICU during the post­operative time period. The actual troubles precipitating their ICU admissions occurred after the first postoperative day, which is when many centers that routinely admit persons to the ICU postoperatively transfer patients to the surgical ward. Considering the character of the complications, seems like improbable that they would have been avoided had we admitted these 3 sufferers to the ICU just after medical operation.

Our own practical experience displays that most elective infrarenal AAA patients proceeding with open re­pair can be without risk admitted to an SDU for postoperative management, and that routine postoperative ICU admission is unnecessary. Being able to supply harmless, efficient postopera­tive care while sparing valuable and expensive ICU means is a vital benefit of this strategy.
