Role of hemogram parameters as predictive markers for propofol injection pain in reproductive and postmenopausal women: a prospective study

Abstract

Aims: In clinical practice, propofol injection pain (PIP) is a frequent condition that clinicians could face every day. The aim of this prospective study was to investigate the correlation between PIP and hemogram parameters in reproductive and postmenopausal women.
 Methods: In this prospective study, 40 reproductive and 40 postmenopausal female patients who underwent elective surgery were enrolled. Baseline data including age, weight, height, hemogram parameters, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and systemic immune inflammatory score (SII) were recorded preoperatively. The pain was classified as 0: no pain, 1: mild pain, 2: moderate pain, 3: severe pain. Patients were previously informed about the questioning of pain scores during propofol.
 Results: The proportion of patients experiencing PIP in postmenopausal (n=16;40%) group was significantly higher than those in the reproductive group (n=6;15%) (p=0.009). When reproductive and postmenopausal groups were compared according to the presence or absence of pain, no difference was found between the groups in terms of hemogram ratios and platelet indices (p>0.05). The NLR, PLR and SII ratios were not significant in predicting the presence of PIP. 
 Conclusion: The findings of our study showed that the occurrence of PIP in postmenopausal women was higher compared to women in reproductive age. Hemogram values, NLR platelet, PLR and SII ratios were not significantly associated with the presence of PIP.
