“…In addition, PH higher than 7.45 was considered alkalemia and lower than 7.35 was recorded as acidemia, PCO2 higher than 45mmHg was considered as respiratory acidosis and lower than 35mmHg as respiratory alkalosis. HCO3 higher than 26mEq/L was metabolic alkalosis and lower than 22 mEq/L was recorded as metabolic acidosis [ 26 , 27 ]. Furthermore, the Sysmex kx21 device was used to run blood tests and determine the levels of Hb.…”

Objective:To evaluate the prognostic value of arterial blood gas (ABG) indices, especially base excess (BE), regarding the severity of traumatic injury.Methods:A total number of 96 trauma patients with fractures of femur and pelvis were included in this study. Demographic characteristics and clinical information of samples were recorded. The results of ABG test and hemoglobin (Hb) were evaluated at two time intervals (on admission and 6 hours later). The outcome of the patients was evaluated at the end of the study (dead or alive). The ABG indices included O2 saturation (O2Sat), PH, PO2, PCO2, bicarbonate (HCO3) and base excess (BE). The mean of the hemodynamic and ABG indices were compared between those who were discharged and mortality cases. The confounders were compensated using a multivariate logistic regression model. Results:Overall 94 trauma patients with long and pelvic fractures were included. There were 69 (73.4%) men and 25 (26.6%) women among the patients with mean age of 37.43 ± 20.07 years. The mortality rate was 10 (10.6%). The most common mechanism of injury was motorcycle accident in 41 (43.6%) and car collision in 43 (45.7%) patients. We found that mortality was significantly associated with amount of FFP transfusion (p=0.005), but was not associated with amount of transfused packed cells (p=0.113). We also found that mortality was associated with lower BP after 6 hours of admission (p=0.001), higher HR on admission (p=0.036), lower HR after 6 hours (p=0.017), lower O2Sat on admission (p<0.001), higher PCO2 after 6 hours and lower BE on admission (p=0.025). Conclusion: The ABG indices including O2Sat, BE and PCO2 are considered prognostic determinants of outcome in trauma patients with long and pelvic fractures. These findings can be considered as fundamental studies to achieve new diagnostic methods.

“…In 1989, Diab and Kiani invented a new type of pulse oximeter with Signal Extraction Technology (SET), a set of proprietary signal processing algorithms that make it possible to obtain more accurate oxygen saturation and pulse rate readings even during challenging conditions such as patient motion and low perfusion (25). Many studies have shown Masimo SET pulse oximetry to be more reliable and accurate than other pulse oximetry technologies in clinically unstable conditions such as in critically ill patients in the ICU, NICU, after cardiopulmonary bypass and cardiac surgery and in the paediatric postanaesthesia care unit (22–24).…”

AimTo assess the time to obtain reliable oxygen saturation readings by different pulse oximeters during neonatal resuscitation in the delivery room or NICU.MethodsProspective study comparing three different pulse oximeters: Masimo Radical-7 compared simultaneously with Ohmeda Biox 3700 or with Nellcor N395, in newborn infants who required resuscitation. Members of the research team placed the sensors for each of the pulse oximeters being compared simultaneously, one sensor on each foot of the same baby. Care provided routinely, without interference by the research team. The time elapsed until a reliable SpO2 was obtained was recorded using a digital chronometer. Statistical comparisons included chi-square and student's T-test.ResultsThirty-two infants were enrolled; median gestational age 32 weeks. Seventeen paired measurements were made with the Radical-7 and Biox 3700; mean time to a stable reading was 20.2 ± 7 sec for the Radical-7 and 74.2 ± 12 sec for the Biox 3700 (p = 0.02). The Radical-7 and the N- 395 were paired on 15 infants; the times to obtain a stable reading were 20.9 ± 4 sec and 67.3 ± 12 sec, respectively (p = 0.03).ConclusionThe time to a reliable reading obtained simultaneously in neonatal critical situations differs by the type of the pulse oximeter used, being significantly faster with Masimo Signal Extraction Technology. This may permit for better adjustments of inspired oxygen, aiding in the prevention of damage caused by unnecessary exposure to high or low oxygen.

“…Pulse oximeters measure changes in the light absorption emitted by a transductor with two different wavelengths (red and infrared) and captured by a photodetector coinciding with pulsatile dilatation and contraction of peripheral arteries using spectrophotometric principles. Using an ad hoc algorithm, changes in both light transduction wave lengths are converted into arterial oxygen saturation values (8). The interpretation of the values of oxygen saturation given by the pulse oximeter correlate with the affinity of Hb for oxygen and this is clearly influenced by the amount of fetal Hb (HbF) (9).…”

Oxygen Supplementation During Preterm Stabilization and the Relevance of the First 5 min After Birth

et al. 2020

Fetal to neonatal transition entails cardiorespiratory, hemodynamic, and metabolic changes coinciding with the switch from placental to airborne respiration with partial pressures of oxygen of 4-5 kPa in utero raising to 8-9 kPa ex utero in few minutes. Preterm infants have immature lung and antioxidant defense system. Very preterm infants (<32 weeks' gestation) frequently require positive pressure ventilation and oxygen to establish lung aeration, a functional residual capacity, and overcome a tendency toward hypoxemia and bradycardia in the first minutes after birth. Recent studies have shown that prolonged bradycardia (heart rate <100 beats per minute) and/or hypoxemia (oxygen saturation <80%) are associated with increased mortality and/or intracranial hemorrhage. However, despite the accumulated evidence, the way in which oxygen should be supplemented in the first minutes after birth still has not yet been clearly established. The initial inspired fraction of oxygen and its adjustment within a safe arterial oxygen saturation range measured by pulse oximetry that avoids hyper-or-hypoxia is still a matter of debate. Herewith, we present a current summary aiming to assist the practical neonatologist who has to aerate the lung and establish an efficacious respiration in very preterm infants in the delivery room.
