Kidney transplantation provides patients with ESRD an opportunity to continue living without the need for frequent dialysis; improving quality of life and reduces mortality. Kidney transplants can either be from a deceased donor (aka cadaveric) or from a living donor, at times genetically related to the patient (aka living related), but not always (aka living-unrelated).
Preoperative management
Patient evaluation
| System | Considerations |
|---|---|
| Neurologic | Peripheral neuropathy may be concurrent with diabetic nephropathy, and may also signal autonomic neuropathy |
| Cardiovascular | CHF is common in undialyzed patients |
| Pulmonary | Pleural effusions and pleuritis may occur in this patient population. Increased susceptibility to infection is common in patients with uremia. |
| Gastrointestinal | Gastroparesis may occur in diabetic patients with autonomic neuropathy |
| Hematologic | Many patients will have chronic anemia as a result of low EPO |
| Renal | Most patients will have ESRD, will need preop potassium check. May need to avoid or decrease dose of renally-metabolized meds. Most recipients also suffer from long-standing, HTN and its systemic concequences. |
| Endocrine | If diabetic nephropathy is cause of ESRD, patient is likely to have other complications of severe diabetes |
| Vascular | Many patients have coronary arterial, cerebrovascular, and peripheral vascular disease in addition to their HTN. |
Labs and studies
- CBC (pay attention to Hb for likely chronic anemia secondary to low erythropoietin production)
- BMP (pay attention to K which may be elevated in ESRD)
Operating room setup
- Prepare arterial line setup
- Have mannitol (preferably warmed to prevent crystallization), furosemide, heparin in room
- May need steroid and/or anti-thymocyte globulin prepared
Patient preparation and premedication
- Midazolam, Tylenol
Regional and neuraxial techniques
- Epidural or CSE may be used for postop pain management
- Pre-emergence TAP catheter vs single-shot
Intraoperative management
Monitoring and access
- After induction of anesthesia, a 3-way Foley catheter is placed into the bladder.
- Arterial line for blood pressure monitoring and frequent lab draws
- IVs and arterial lines should avoid the side of AV fistula if present
Induction and airway management
- If K<5.5, succinylcholine may be used as a paralytic, otherwise, cisatracurium or rocuronium may be used
Positioning
- Supine
- Avoid pressure on AV fistula which may lead to thrombosis. Must be carefully padded.
Maintenance and surgical considerations
- Be generous with fluids to maintain a temporarily hypervolemic state prior to diuretics
- Choice of fluids: balanced electrolyte solution (Plasmalyte, Normosol, or Lactated Ringer) vs normal saline
- Historically normal saline was the fluid of choice. Recent study showed are lower rates of delayed graft function (30 versus 40 percent in NS group; BEST-Fluids trial[1]). Additionally, many institutions have changed to balanced electrolyte solutions due to high rates of hyperchloremic metabolic acidosis[2] seen in large volume NS administration (leading to similar intracellular K+ rates). NS also increased need for vasoactives intraop in this study.
- Choice of fluids: balanced electrolyte solution (Plasmalyte, Normosol, or Lactated Ringer) vs normal saline
- Avoid hypothermia with forced-air warmer +/- room temperature optimize allograft perfusion (2/2 increased release of catecholamines), bleeding, NMBD duration of action, cardiac events, and SSI rates
- After anastamoses are made, give mannitol (12.5 g-25 g) and Lasix (~100 mg)
- Anticipate prolonged drug effects for renally metabolized/excreted medications
- Avoid meperidine (which may accumulate as normeperidine > CNS toxicity)
- Renal artery and vein clamps will occur, though generally with minimal effect on overall hemodynamics
- Will be instructed to clamp Foley by surgeons
- May be requested to give steroids and anti-thymocyte antibody to prevent organ rejection
Emergence
- Patients are usually extubated in the OR
- Ensure adequate NMB reversal
Postoperative management
Disposition
- Usually to PACU
- Patients with other concurrent transplants (pancreas, liver, etc) may be monitored in the ICU
Pain management
- PCA
- Epidural
- TAP block
Potential complications
- Fistula thrombosis if improperly padded
- Hemorrhage
- Delayed urine output, dialysis may be necessary until renal function returns
- Bucking or coughing during emergence may lead to forceful tugging on transplanted kidney and disruption of anastomoses
