Table 4.
Preoperative factors |
|
Patients orthostatic hypotension with or without supine hypertension |
Be aware of gastroparesis and aspiration risk |
Be aware of blood volume status for the conduct of anesthesia |
Be aware of slight anemia due to reduced erythropoiesis |
Consider holding oral vasopressors to prevent drug interactions intraoperatively |
|
Intraoperative factors |
|
General versus regional anesthesia choice would be dependent on procedure type |
Patients require adequate monitoring and constant vigilance |
Hypothermia and hyperthermia are both risks with poor thermal regulation |
Intubation may require rapid sequence with cricoid pressure |
Patient positioning may have significant effects on vital signs |
Nitroglycerine, prone positioning or reverse trendelenberg can be used for supine hypertension |
Sudden blood volume changes may precipitate untoward blood pressure response (rapid infusions or rapid blood loss) |
Pneumoperitoneum should be applied with extreme caution or avoided if possible |
Vasopressors and Inotropes can have resistance or undue sensitivity (See Table 3.) |
Abnormal electrolyte values affect responses to medications |
|
Postoperative factors |
|
Anticipate volume changes in the postoperative period and observe with a higher level of care |
Orthostatic hypotension requires good blood volume and assistance with first ambulation |
Abnormal electrolyte values affect responses to medications |
Thermal regulation may be an issue in the recovery period |
Ileus can be worsened by opiate use in the postoperative period |
Restart home dysautonomia medications before discharge |
