She had an IV, a catheter, oxygen.
‡Mask oxygen therapy (n=5); nasal catheter oxygen therapy (n=13).
Standard resuscitation of a patient with an S-ICA includes intravenous lines (two wide bore intravenous lines if the patient has hypovolaemic shock), a urinary catheter, oxygen via facemask and blood transfusion as required (Table 1).> There was no significant improvement in mean blood pressure following resuscitation in the SAMM group (p 0.67), nor in the maternal death group (p 0.883).
Instead, we offered one more option: a bypass machine for a process called Extracorporeal Membrane Oxygenation (ECMO) that would draw blood out of his sister's body through a large catheter, add oxygen and remove carbon dioxide, and then return the blood back to her.
Rudolf and Hohenhorst [ 45] performed a study in which ventilation was achieved through an intratracheal catheter delivering oxygen at a rate of 0.5 l.min−1.
Throughout the operation, we monitored the patient's electrocardiogram, arterial pressure, central venous pressure (with an internal jugular vein catheter), percutaneous oxygen saturation, urine volume, capnography, and the bispectral index.
During sampling with the mini-BAL catheter, arterial oxygen saturation (SpO2), haemodynamics (heart rate (HR), systemic arterial pressure (SAP)) and ventilatory variables (expiratory tidal volume (Vt), minute volume (VE), auto PEEP, peak pressure (Ppeak), and Pplat) were recorded.
AUC: area under the curve; CPB: cardiopulmonary bypass; CVC: central venous catheter; DO2: oxygen delivery; ICU: intensive care unit; NIRS: near-infrared spectroscopy; NPV: negative predictive value; PPV: positive predictive value; RBC: red blood cell; ROC: receiver operating characteristic; rSO2: regional oxygen saturation; ScVO2: central venous oxygen saturation; VO2: oxygen consumption.
After placing a minimally invasive, flexible catheter partial oxygen tension microprobe (polarographic Clark-type cell O2-sensor; Licox® system, GMS, Kiel, Germany) into the left ventricular anterior wall, baseline data were obtained after an equilibration period of 40 min. Hearts were then subjected to 2 h at 10°C of cardioplegic ischaemia and reperfused.
This series of single-centre studies with impressive positive results is in sharp contrast to the negative results of the multicenter study by Sandham et al. [ 14], where patients undergoing major surgery were randomised to receive pulmonary artery catheter with oxygen transport-driven guidelines for peri- and postoperative haemodynamic management versus conventional management.
