Objective:To explore the effect of intraspinal labor analgesia on labor progress, maternal and infant outcomes.Methods:Two hundred cases of full-term singleton primiparous women in head position admitted to the Second Affiliated Hospital of Shantou University Medical College from March 2019 to March 2020 were selected as the research subjects. According to the random number table method, they were divided into the control group (100 cases, natural delivery) and the analgesia group (100 cases, analgesia delivery). The visual analoguescore (VAS), progress of labor, and the outcome of delivery between the two groups werecompared.Results:The VAS scores of the analgesic group at 10, 30 and 60 min after analgesia were lower than those in the control group: (1.30 ± 0.17) scores vs. (9.50 ± 0.53) scores, (0.50 ± 0.22) scores vs. (9.50 ± 0.16) scores, (0.40 ± 0.28) scores vs. (9.50 ± 0.34) scores, the differences were statistically significant ( P<0.05). The first stage of labor in the analgesia group was longer than that in the control group: (347.6 ± 54.4) min vs. (325.8 ± 58.5) min; but the active stage, the second stage of labor, the third stage of labor and the total duration of labor in the analgesia group were shorter than those in the control group: (184.3 ± 39.5) min vs. (202.9 ± 42.7) min, (57.8 ± 17.9) min vs. (85.3 ± 16.9) min, (7.7 ± 5.0) min vs. (16.3 ± 5.2) min, (503.6 ± 131.4) min vs. (596.5 ± 175.7) min, the differences were statistically significant ( P<0.05). The 2 h and 24 h postpartum hemorrhage in the analgesia group were significantly lower than those in the control group: (223.64 ± 80.34) ml vs. (276.97 ± 82.35) ml, (331.57 ± 92.47) ml vs. (384.59 ± 94.25) ml, the differences were statistically significant ( P<0.05). The rate of normal delivery and the use of oxytocin in the analgesia group were higher than those in the control group: 91.0%(91/100) vs. 75.0%(75/100), 83.0%(83/100) vs. 49.0% (49/100), the differences were statistically significant ( P<0.05). In the newborn Apgar scores, the muscle tension, pulse, reflex response, respiration score and total score in the analgesia group were significantly higher than those in the control group ( P<0.05). The neonatal distress in the analgesia group was lower than that in the control group: 4.0%(4/100) vs. 15.0%(15/100), the difference was statistically significant ( P<0.05). Conclusions:Intravertebral labor analgesia can shorten the time of parturient delivery, reduce postpartum hemorrhage, improve the Apgar score of newborns, increase the pregnancy rate, and improve maternal and infant outcome.

Objective To explore whether the pattern of dysphagia verified using videofluoroscopic swallowing study (VFSS) was associated with the Iocation of the infarction in stroke patients.Methods Ninety-two patients with dysphagia (admitted between January 2015 and August 2016) who had first onset of cerebral infarction confirmed by magnetic resonance imaging were included in this study.They were divided into a unilateral brainstem group (n =29),a left hemisphere (cortex + white matter) group (n =37) and a right hemisphere (cortex + white matter) group (n=26) according to the location of the stroke.All subjects were evaluated using VFSS,and the oral transit time (OTT),triggering of pharyngeal swallowing (TPS),presence of residue in the vallecular and pyriform sinus,penetration,aspiration,cough reaction and upper esophageal sphincter (UES) opening were recorded and compared among the three groups.Results There were no significant differences among the three groups in OTT (X2 =0.712,P=0.918),TPS (1.564,P =0.458),penetration (X2 =5.615,P=0.060) and cough reaction (X2 =5.882,P=0.053).The unilateral brainstem group had significantly more residue in the vallecular and pyriform sinus than the left hemisphere group (X2=6.508,P=0.011).Aspiration was significantly more frequently found in the unilateral brainstem group than in the left hemisphere group (X2=7.803,P =0.005).The unilateral brainstem group was more likely to have insufficient UES opening than the left hemisphere (X2=29.555,P<0.001) and right hemisphere groups (X2=24.630,P<0.001).Conclusions Unilateral brainstem stroke is more likely to cause dysphagia than the unilateral cerebral hemisphere stroke,characterized by the abnormal residue in the vallecular and pyriform sinus,aspiration and the degree of UES opening.No significant differences were found in the dysphagia between stroke survivors with stroke in right and left hemispheres.
