Table 1 Monitoring procedures during abdominal normothermic oxygenated recirculation
Monitored parameters | Objectives | Type of monitoring | Corrective actions |
|---|---|---|---|
Pump flow rate | 2.5 to 3 l/min | Continuous monitoring | Vascular filling: saline and hydroxyethyl starch (10 ml/(kg h)) |
Mean arterial pressure | >60 mmHg | Continuous infusion of noradrenalin on the circuit | |
Central venous pressure | <5 mmHg | — | |
pH | 7.5 | Blood samples on the circuit every 30 minutes | Continuous infusion of sodium bicarbonate on the circuit |
Partial pressure of carbon dioxide | 30 to 40 mmHg | Sweeping gas flow adjustment | |
Partial pressure of oxygen | 100 to 150 mmHg | Fraction of inspired oxygen adjustment | |
Activated clotting time | >200 s | Bolus of 5000 IU unfractionated heparin on the circuit |
