RESUMO

INTRODUCTION: Postoperative analgesia in elderly patients is still a thorny problem. Ultrasound-guided oblique subcostal transverse abdominis plane block (TAPB) has been demonstrated to provide postoperative analgesia after abdominal surgeries. However, recent studies have suggested that an alternative method, erector spinae plane block (ESPB), might also be effective. In this study, we compared the postoperative analgesic effects of ESPB and TAPB in elderly patients who had undergone laparoscopic colorectal surgery. METHODS: Sixty-two elderly patients (≥ 65 years old) scheduled for elective laparoscopic colorectal surgery with general anesthesia were randomly allocated to two equally sized groups: ESPB group and TAPB group. The ESPB group had a bilateral erector spinae plane block, and the TAPB group had a bilateral oblique subcostal transverse abdominis plane block. The primary outcome was visual analogue scale (VAS) pain score during the first 24 postoperative hours at resting and active states. The secondary outcomes were postoperative consumption of sufentanil, satisfaction score, the number of patients who required antiemetics, incidence of block-related complications, and other side events. RESULTS: There were no demographic differences between two groups. Compared to the TAPB group, the ESPB group had lower VAS pain scores and sufentanil consumption during the first 24 postoperative hours. Additionally, ESPB reduced the occurrence of postoperative nausea and vomiting. Furthermore, the satisfaction score was higher in the ESPB group. No other complications were reported between the two groups. CONCLUSIONS: Compared with oblique subcostal TAPB, ESPB more effectively reduced postoperative pain and opioid consumption. Thus, ESPB is suitable for postoperative analgesia in elderly patients who have undergone laparoscopic colorectal surgery. TRIAL REGISTRATION: Chinese Clinical Trial Registry: ChiCTR2000033236.

RESUMO

OBJECTIVE@#To investigate the clinical characteristics of myelodysplastic syndrome (MDS) with TP53 mutant and the relationship between TP53 mutation and monosomal karyotype in MDS patients.@*METHODS@#The TP53 mutations in 102 patients with de nove MDS were retrospectively analyzed, and the clinical features of the TP53 mutation group and the non-mutation group were compared. The relationship between TP53 mutation and karyotype, especially monosomal karyotype was analyzed.@*RESULTS@#Fifty-two out of the 102 MDS patients were male and 50 were female, the median age was 59.5 (23-83) years old. The mutational frequency of TP53 was 12.7%, which mostly occurred in patients with MDS-EB. As compared with non-mutation group, the hemoglobin level and platelet count were lower (P=0.001, P=0.033), the LDH level and bone marrow blast ratio were higher in TP53 mutation group (P=0.002, P<0.001), but the statistical difference of alsolute count of neutrophils and levels of serum ferritin and β2-microglobulin between 2 groups was not found. The karyotype abnormality frequency of patients with TP53 mutation was 90.9%, among them 72.7% was monosomal karyotype. The incidence of monosomal karyotype in the TP53 mutation group was very significantly higher than that in the non-mutation group (P<0.001). MDS with TP53 mutation and monosomal karyotype appeared in the groups with high and very high IPSS-R risk.@*CONCLUSION@#MDS patients with TP53 mutation have unique clinical features and high incidence of monosomal karyotype, and their overall prognosis is poor.
