This work was aimed to study the analgesic effect of pudendal nerve block on obstetrics and gynecology under the guidance of ultrasound image based on optimized fast super resolution reconstructed convolutional neural network (FSRCNN) algorithm. A total of 110 primiparas from hospital who gave birth through vagina were randomly rolled into experimental group (55 cases) and control group (55 cases). The optimized FSRCNN algorithm was constructed, compared with the FSRCNN algorithm and the Bicubic algorithm and applied to 110 cases of maternal patients undergoing perineotomy under ultrasound image-guided pudendal nerve block. Visual analogue scoring (VAS), incision suture pain VAS score, occurrence of complications, puerpera labor time, and newborn weight were recorded and compared, so did Apgar score of newborns, numbness of maternal thigh, recovery of puncture site, and satisfaction of maternal analgesia. The results showed that the peak signal-to-noise ratio (PSNR) of the high-resolution image reconstructed by the FSRCNN algorithm was 32.68 dB and that reconstructed by the optimized FSRCNN algorithm was 32.19 dB. The PSNR of the Bicubic algorithm processed image was 28.51 dB. In the lateral resection of episiotomy in the second stage of labor, the visual analog score (2.3 ± 1.5 points) of the experimental group was inferior to that of the control group (7.1 ± 2.6 points) ( P < 0.05 ). The visual analogue score of stitch pain (1.3 ± 0.8 points) was also inferior to that of the control group (5.2 ± 1.9 points) ( P < 0.05 ). Moreover, the satisfaction of the parturients in the experimental group (9.86 ± 0.41 points) was considerably superior to that of the control group (7.36 ± 1.25 points) ( P < 0.05 ). In short, the optimized FSRCNN algorithm had a short training time and good reconstruction effect. Ultrasound-guided pudendal nerve block had a substantial analgesic effect on the second stage of labor and improved parturients’ satisfaction.

Local Infiltration Of Analgesia

Abstract Background Episiotomy or tearing of perineal tissues during childbirth is associated with significant pain in the postpartum period. Although the use of episiotomy is often debated, it remains the most common surgical procedure experienced by women. Pain from episiotomy is poorly treated, though it may be severe and can result in significant discomfort and interference with basic daily activities and adversely impact motherhood experiences. Local infiltration analgesia is the most commonly used method of analgesia during normal labor. This type of local analgesia is achieved by injecting the analgesic agent into the perineum just before delivery with crowning of the fetal head. It is also widely used just before an episiotomy. This study compares the efficacy and duration of pudendal nerve block versus local infiltration on post episiotomy pain relief. Aim of the Work: This study aims to compare the effect of Pudendal Nerve Block with perineal local infiltration of analgesia in post episiotomy pain relief. Study design:Prospectiverandomizedcontrolledclinicaltrial. Patients & Methods The current study was conducted in Ain Shams University Maternity Hospital in the period between August 2018 and Jan 2019. It included 100 primigravida women in labor meeting inclusion criteria attending the causality of Ain Shams Maternity Hospital. Results Our study showed statistically significant decrease mean of study group compared to control group according VAS score from after 1hr to after 6hrs. Also there was statistically significant decrease in patients' need for analgesia in study group compared to control group from after 1hr to after 6hrs. Patients were asked about episiotomy pain and were advised not to be distracted by pain of uterine contraction or any other pain she complains of as much as possible not to alter the study results Regarding the pudendal nerve block group none of the patients receiving effective bilateral pudendal nerve block asked for analgesia during the first hour post injection. Two patients representing 4.4% of the study group asked for analgesia after two hours post injection, by the 3rd hour 6 patients representing 13.3% of the study group asked for analgesia. After completing 6 hours post injection follow up only 21 patients asked for analgesia representing 46.7% of the study group while 24 patients (53.3%) did not require any analgesia for the first 6 hours after injection of pudendal nerve block Conclusion There is statistically significant decrease in mean VAS in pudendal nerve block compared to local perineal infiltration of analgesia from after 1hr to after 6hrs of injection. Also there is statistically significant decrease in patients' need for analgesia in case of pudendal nerve block compared to local perineal infiltration of analgesia from after 1hr to after 6hrs of injection. There is highly statistically significant increase mean of delivery time after injection (min) in pudendal nerve block compared to local perineal infiltration of analgesia but it has no clinical significance. There are no neonatal side effects or complications of pudendal nerve block.

AbstractThirty (30) adult male goats were injected xylazine (0.05 mg/kg, IM) and randomly divided into three equal groups. Internal pudendal nerve block was tried using 3.5 ml (on each side) of 1% lignocaine hydrochloride byischiorectal fossa or ischial arch approaches in goats from Group 1 and Group 2 respectively, 15 minutes after giving xylazine. Inadvertent puncture of the rectal wall and prick to the finger placed in the rectum was experienced once in Group 1 animal. None of the animals showed protrusion of the penis without manual manipulation. Prolapse of the prepucial ring was noticed in three animals from Group 1 and two each from Group 2 and 3. The application of mild manual push percutaneously resulted in the exposure of the penis in eight and six animals belonging to Group 1 and Group 2 respectively, 15 minutes after injection of the local anaesthetic. Statistically significant (P>0.05) difference between Group 1 and 2 values was detected only once at 90 minutes following injection of the local anaesthetic. The block lasted longer in animals of Group 1. The exposed organ was flaccid and insensitive. The organ retracted into the prepucial cover within five minutes of its release in all the animals. The penile exposure could not be achieved by similar manipulation in any of the Group 3 animals. From this study it was concluded that the ischiorectal fossa approach is cumbersome and may lead to inadvertent punctures, but the block develops in more number of animals for a longer period than with the ischial arch approach. The outcome of the two techniques did not show statistically significant (P>0.05) difference for most of the assessment period. Reducing the concentration of lignocaine hydrochloride may reduce the chances of continued relaxation of the penis beyond the required period and also the drug toxicity. However, studies using larger volume of 1% lignocaine hydrochloride may be undertaken for short term exposure of the penis without manual manipulation.

Background The aim of this study was to assess the effect of an external nasal dilator on several variables characterizing labor in both mother and fetus. Methods One hundred and fifty primigravida women in active labor were randomized to wear, throughout labor, either a dilator spring-loaded nasal strip or a placebo device. Data were obtained during labor and compared between the groups. After delivery, the satisfaction rate was assessed. Results No differences were found between the study and the control group regarding rate of induction or augmentation of labor as well as Montevideo units reached, frequency of rupture of membranes, duration of the active phase and second stage of labor, usage of epidural analgesia, normal fetal heart pattern, meconium-stained amniotic fluid, and neonatal well being. Length of maternal and neonatal hospitalization also did not differ between the groups. Satisfaction rate was significantly higher in parturient women wearing nasal strips with a dilator spring than in parturient women wearing a placebo spring (P < 0.0001). Conclusion Nasal strips do not change the course but ameliorate the quality of labor by improving the ease of breathing. Nasal dilators sustain the respiratory effort associated with the long process of labor and may control the switch from nasal to oronasal breathing during delivery.
