- See also preoperative care
Perioperative care is defined as "interventions to provide care prior to, during, and immediately after surgery."[1]
[]
Classification
Intraoperative Care
Postoperative Care
Components of postoperative care may include incentive spirometry.
Complications
Myocardial ischemia and infarction
In noncardiac surgery, myocardial ischemia is more common during the postoperative period than during or before surgery.[2]
In coronary artery bypass surgery, ischemia is common after release of aortic occlusion.[3] Ischemia may be better detected by transesophageal echocardiography than by continuous electrocardiography.[4]
Perioperative myocardial infarction has been reviewed.[5]
Myocardial infarction is usually NSTEMI.[6][2][7] Transmural infarctions may occur, but tend to occur later (one week) during hospitalization and are more likely to be transmural.[6]
Older studies showed higher mortality, perhaps due to only detecting large infarctions.[8]
Respiratory complications and pneumonia
Pulmonary embolism
Septic shock
Sepsis and septic shock may be the most common complications in perioperative care.[9]
Specific interventions
Medical consultation
The benefits of medical consultation are not clear in an observational study.[10]
Anemia
"The administration of oral iron supplements to elderly, healthy orthopedic patients postoperatively did not hasten the recovery of hemoglobin levels, provided adequate tissue iron stores were present." according to a randomized controlled trial.[11]
"Both modified epoetin alfa regimens were effective compared with placebo in reducing allogeneic transfusion in patients undergoing hip arthroplasty" according to a randomized controlled trial.[12]
Among patients receiving coronary artery bypass grafting, there may be no meaningful difference between transfusing to maintain a hemoglobin levels > 8 g/dL versus a hemoglobin levels > 9 g/dL.[13] However, hemoglobin levels < 8 g/dL may increase complications.[14]
Glucose control
| Trial | Patients | Intervention | Comparison | Outcome | Results | Sources of bias | |
|---|---|---|---|---|---|---|---|
| Intervention | Control | ||||||
| Subramaniam[15] 2009 |
236 patients for vascular surgery or lower limb amputation | Continuous insulin infusion with target glucose 100-150 mg/dl | Intermittent insulin bolus if glucose > 150 mg/dl | "Composite of all-cause death, myocardial infarction, and acute congestive heart failure" (stroke not studied) Blinding not stated |
3.5% | 12.3% | Unblinded Early termination and without adjustment of p-value |
| Gandhi[16] 2007 |
400 patients for cardiac surgery | Continuous insulin infusion with target glucose 80-100 mg/dl | Insulin bolus or continuous if glucose > 200 mg/dL | "Composite of death, sternal infections, prolonged ventilation, cardiac arrhythmias, stroke, and renal failure within 30 days" Blinded end point assessment |
44% (but significantly more strokes) |
46% | None |
Regarding intraoperative control of glucose, a randomized controlled trial concluded "the increased incidence of death and stroke in the intensive treatment group raises concern about routine implementation of this intervention."[16] An second randomized controlled trial that was unblinded, stopped early, and had an imbalance in the age between the two treatment groups found benefit.[15][17]
Hemodynamic interventions
"The use of a preemptive strategy of hemodynamic monitoring and coupled therapy reduces surgical mortality and morbidity" according to a meta-analysis of trials. [18]
