RESUMO

Objective: To investigate the association between CYP3A4∗1G and OPRM1A118G gene polymorphisms and postoperative analgesia with sufentanil in women of Zhuang ethnicity from western Guangxi, China. Methods: Forty-eight Chinese Zhuang women who underwent elective myomectomy under general anesthesia in our hospital from January 2019 to December 2020 were selected, and another 47 Chinese Han patients in the same period were selected as the control subjects. CYP3A4∗1G and OPRM1 A118G gene polymorphisms as well as sedation and pain scores at different time points after surgery were compared between the two groups of patients to analyze the relationship between the degree of pain and dosage of sufentanil and to analyze the effect of gene polymorphisms on the occurrence of adverse reactions. Results: The frequencies of ∗1/∗1G and ∗1G/∗1G genotypes, allele 1∗G of CYP3A4∗1G and genotypes AA, and allele A of OPRM1 A118G in Zhuang patients were lower than those in Han patients, while the frequencies of ∗1/∗1, allele ∗1 of CYP3A4∗1G and genotypes AG, genotypes GG, and allele G of OPRM1 A118G were higher in Zhuang women. There was no significant difference in the Ramsay and VAS scores between the two groups at different time points after surgery, but the sufentanil use in Zhuang patients was higher than in Han patients at different time points after surgery. In addition, sufentanil use was highest in Zhuang patients with the ∗1/∗1 genotype of the CYP3A4∗1G gene. No significant difference was found in the incidence of adverse reactions during analgesia between the two groups. Conclusion: CYP3A4∗1G could be associated with postoperative sufentanil analgesia in Zhuang patients in western Guangxi and should be considered when developing personalized analgesia regimens.

RESUMO

BACKGROUND: Restrictive blood transfusion is recommended by major guidelines for perioperative management, but requires objective assessment at 7-10 g/dl haemoglobin (Hb). A scoring system that considers the physiological needs of the heart may simply the practice and reduce transfusion. METHODS: Patients (14-65 years of age) undergoing non-cardiac surgery were randomised at a 1:1 ratio to a control group versus a Perioperative Transfusion Trigger Score (POTTS) group. POTTS (maximum of 10) was calculated as 6 plus the following: adrenaline infusion rate (0 for no infusion, 1 for ≤0.05 µg·kg-1 ·min-1 , and 2 for higher rate), FiO2 to keep SpO2 at ≥95% (0 for ≤35%, 1 for 36%-50%, and 2 for higher), core temperature (0 for <38°C, 1 for 38-40°C, and 2 for higher), and angina history (0 for no, 1 for exertional, and 2 for resting). Transfusion is indicated when actual Hb is lower than the calculated POTTS in individual patients. Transfusion in the control group was based on the 2012 American Association for Blood Banks (AABB) guideline. The primary outcome was the proportion of the patients requiring transfusion of allogeneic red blood cells (RBCs) during the perioperative period (until discharge from hospital), as assessed in the intention-to-treat (ITT) population (all randomised subjects). RESULT: A total of 864 patients (mean age 44.4 years, 244 men and 620 women) were enrolled from December 2017 to January 2021 (433 in the control and 431 in the POTTS group). Baseline Hb was 9.2 ± 1.8 and 9.2 ± 1.7 g/dl in the control and POTTS groups, respectively. In the ITT analysis, the proportion of the patients receiving allogeneic RBCs was 43.9% (190/433) in the control group versus 36.9% (159/431) in the POTTS group (p = 0.036). Lower rate of allogeneic RBCs transfusion in the POTTS group was also evident in the per-protocol analysis (42.8% vs. 35.5%, p = 0.030). Transfusion volume was 4.0 (2.0, 6.0) and 3.5 (2.0, 5.5) units (200 ml/unit) in the control and POTTS groups, respectively (p = 0.25). The rate of severe postoperative complications (Clavien-Dindo grade IIIa and higher) was 3.9% in the control group versus 1.2% in the POTTS group (p = 0.010). CONCLUSION: Transfusion of allogeneic RBCs based on the POTTS was safe and reduced the transfusion requirement in patients undergoing non-cardiac surgery.
