Birthing ball on promoting cervical ripening and its influence on the labor process and the neonatal blood gas index

BACKGROUND Term pregnancy-induced labor refers to the use of artificial methods to induce uterine contractions and terminate pregnancy after 37 wk.It is a common method to prevent overdue pregnancy and to deal with high-risk pregnancies.In addition,it can alleviate maternal complications and cause the fetus to leave the adverse intrauterine environment early,which is beneficial to the outcome of pregnancy.AIM To explore the effect of a birthing ball on labor by inducing cervical ripening and its influence on labor and the neonatal blood gas index.METHODS Twenty-two women who were scheduled to undergo labor induction and delivery in the obstetrics department of our hospital were randomly divided into two groups:the delivery ball group(childbirth ball combined with COOK balloon induction)and the conventional group(COOK balloon induction alone).The cervical Bishop score before and after intervention,duration of labor at each stage,mode of delivery,neonatal umbilical venous blood pH,oxygen partial pressure(PO_(2)),carbon dioxide partial pressure(PCO_(2)),and the 1-min Apgar score were recorded.RESULTS After the intervention,the cervical Bishop score of the delivery ball group(7.84±1.52)was significantly higher than that of the conventional group(7.32±1.29)(P<0.05),and the cervical Bishop scores of the two groups after intervention were significantly higher than those before intervention(P<0.05).After the intervention,the first stage of labor(510.9±98.7 min),the second stage of labor(43.0±8.5 min),and the total duration of labor(560.0±120.9 min)in the delivery ball group were lower than those in the routine group,with a first stage of labor of 602.1±133.2 min,a second stage of labor of 48.4±9.1 min,and a total duration of labor of 656.8±148.5 min(P<0.05).There was no significant difference in the time of the third stage of labor between the two groups(P>0.05).There was no significant difference in the pH,PO_(2),and PCO_(2) values of newborns between the delivery ball group and the conventional group(P>0.05).The 1-min Apgar score of the delivery ball group was higher than that of the conventional group(9.10±0.38 points vs 8.94±0.31 points,P<0.05).The natural delivery rate of the delivery ball group was higher than that of the conventional group(91.00%vs 78.00%,P<0.05).CONCLUSION The use of a birthing ball combined with a COOK balloon for inducing labor has a better effect on promoting cervical ripening,shortening the time of labor,and improving the Apgar score of newborns.

Lung ultrasound score evaluation of the effect of pressure-controlled ventilation volume-guaranteed on patients undergoing laparoscopicassisted radical gastrectomy

BACKGROUND Laparoscopic-assisted radical gastrectomy(LARG)is the standard treatment for early-stage gastric carcinoma(GC).However,the negative impact of this proce-dure on respiratory function requires the optimized intraoperative management of patients in terms of ventilation.AIM To investigate the influence of pressure-controlled ventilation volume-guaranteed(PCV-VG)and volume-controlled ventilation(VCV)on blood gas analysis and pulmonary ventilation in patients undergoing LARG for GC based on the lung ultrasound score(LUS).METHODS The study included 103 patients with GC undergoing LARG from May 2020 to May 2023,with 52 cases undergoing PCV-VG(research group)and 51 cases undergoing VCV(control group).LUS were recorded at the time of entering the operating room(T0),20 minutes after anesthesia with endotracheal intubation(T1),30 minutes after artificial pneumoperitoneum(PP)establishment(T2),and 15 minutes after endotracheal tube removal(T5).For blood gas analysis,arterial partial pressure of oxygen(PaO_(2))and partial pressure of carbon dioxide(PaCO_(2))were observed.Peak airway pressure(P_(peak)),plateau pressure(Pplat),mean airway pressure(P_(mean)),and dynamic pulmonary compliance(C_(dyn))were recorded at T1 and T2,1 hour after PP establishment(T3),and at the end of the operation(T4).Postoperative pulmonary complications(PPCs)were recorded.Pre-and postoperative serum interleukin(IL)-1β,IL-6,and tumor necrosis factor-α(TNF-α)were measured by enzyme-linked immunosorbent assay.RESULTS Compared with those at T0,the whole,anterior,lateral,posterior,upper,lower,left,and right lung LUS of the research group were significantly reduced at T1,T2,and T5;in the control group,the LUS of the whole and partial lung regions(posterior,lower,and right lung)decreased significantly at T2,while at T5,the LUS of the whole and some regions(lateral,lower,and left lung)increased significantly.In comparison with the control group,the whole and regional LUS of the research group were reduced at T1,T2,and T5,with an increase in PaO_(2),decrease in PaCO_(2),reduction in P_(peak) at T1 to T4,increase in P_(mean) and C_(dyn),and decrease in Pplat at T4,all significant.The research group showed a significantly lower incidence of PPCs than the control group within 3 days postoperatively.Postoperative IL-1β,IL-6,and TNF-αsignificantly increased in both groups,with even higher levels in the control group.CONCLUSION LUS can indicate intraoperative non-uniformity and postural changes in pulmonary ventilation under PCV-VG and VCV.Under the lung protective ventilation strategy,the PCV-VG mode more significantly improved intraop-erative lung ventilation in patients undergoing LARG for GC and reduced lung injury-related cytokine production,thereby alleviating lung injury.
