“…This method uses a catheter which is inserted into the blood vessel and measures the pressure with high accuracy. Nevertheless, such an invasive technique induces potential risk and is uncomfortable for the patient ( Lakhal and Robert-Edan, 2017 ). As a consequence, continuous non-invasive BP monitoring remains an important demand.…”

“…Arterial line cannulation is employed in the operating room and ICU settings to provide easy access for continuous and real-time systemic blood pressure measurements, blood gas analysis, and other laboratory measurements. However, based on evidence, this process is not without risk factors (Lakhal and Robert-Edan 2017). The process of inserting arterial line (over 48 or 72 hours) is an invasive procedure with several complications, for instance infection, local hematoma, vascular injury, thrombosis, disseminated intravascular coagulation, and reduced cardiac output (Sood et al 2010, Long et al 2017, Taghizadieh et al 2016).…”

Background Use of capnography as a non-invasive method during the weaning process for fast track extubation (FTE) is controversial. We conducted the present study to determine whether pulse oximetry and capnography could be utilized as alternatives to arterial blood gas (ABG) measurements in patients under mechanical ventilation (MV) following coronary artery bypass graft (CABG) surgery. Methods In this randomized clinical trial, 70 patients, who were candidates for CABG surgery, were randomly assigned into two equal groups (n = 35); the intervention group and the control group. In the intervention group, the ventilator management and weaning from MV was done using Etco2 from capnography and SpO2 from pulse oximetry. Meanwhile, in the control group, weaning was done based on ABG analysis. The length of intensive care unit (ICU) stay, time to extubation, number of manual ventilator setting changes, and alarms were compared between the groups. Results The end-tidal carbon dioxide (ETCO2) levels in the intervention group were completely similar to the partial pressure of carbon dioxide (PaCo2) in the control group (39.5 ± 3.1 vs. 39.4 ± 4.32, P > 0.05). The mean extubation times were significantly shorter in the intervention group compared to those in the control patients (212.2 ± 80.6 vs. 342.7 ± 110.7, P < 0.001). Moreover, the number of changes in the manual ventilator setting and the number of alarms were lower in the intervention group (P < 0.05). However, the differences in the length of stay in ICU between the two groups were not significant (P = 0.219). Conclusion According to our results, the use of non-invasive monitors, including capnography and pulse oximetry, is emphasized in order to utilize FTE after CABG surgery. Furthermore, it is a safe and valuable monitor that could be a good alternative for ABG in this population. Nevertheless, further studies with larger sample sizes and on different disease states and populations are required to assess the accuracy of our findings.

Radial and femoral artery catheterization is the most common procedure for monitoring patients with shock. However, a disagreement in mean arterial pressure (MAP) between the two sites has been reported. Hence, the aim of this study was to compare the MAP from the radial artery (MAPradial) with that of the femoral artery (MAPfemoral) in patients with refractory shock. A prospective study was conducted in the medical intensive care unit. The radial and femoral were simultaneously measured MAP in the patients every hour, for 24 hours. In total, 706 paired data points were obtained from 32 patients. MAPradial strongly correlated with MAPfemoral (r = 0.89, p <0.0001). However, overall MAPradial was significantly lower than MAPfemoral 7.6 mmHg. The bias between MAPradial and MAPfemoral was -7.6 mmHg (95% limits of agreement (LOA), -24.1 to 8.9). In the subgroup of patients with MAPradial < 65 mmHg, MAPradial moderately correlated with MAPfemoral (r = 0.63) and the bias was increased to -13.0 mmHg (95% LOA, -28.8 to 2.9). There were 414 (58.6%) measurements in which the MAP gradient between the two sites was > 5 mmHg. In conclusion, the radial artery significantly underestimated MAP compared with the femoral artery in patients with refractory shock.
