ABSTRACT
Objective:To systematically evaluate the efficacy of dorsal penile nerve block (DPNB) and caudal block (CB) for analgesia after penile surgery under general anesthesia in the pediatric patients.Methods:Databases including PubMed, EMbase, Web of Science, the Cochrane Library, Wanfang, VIP, CNKI and CBM were searched to collect the randomized controlled trials involving DPNB and CB for penile surgery under general anesthesia in children from inception to September 2021.Meta-analysis was performed using RevMan 5.4 software.Results:Sixteen randomized controlled trials involving 1 271 pediatric patients were enrolled.The results of meta-analysis showed that the requirement for analgesic drugs during recovery was significantly lower in CB group than in DPNB group ( RR=2.54, 95% CI 1.19-5.40, P=0.020); the time of first postoperative activity was significantly shortened ( SMD=-0.68, 95% CI -1.23--0.13, P=0.020), and the incidence of postoperative motor block was decreased ( RR=0.05, 95% CI 0.01-0.16, P<0.001) in DPNB group as compared with CB group.There were no significant differences in the incidence of intraoperative block failure ( RR=1.25, 95% CI 0.62-2.51, P=0.530) between two groups.There were no significant differences in objective pain scores at awakening ( SMD=-0.29, 95% CI -0.01-0.59, P=0.050), at 1 h after surgery ( SMD=1.02, 95% CI -1.37-3.41, P=0.400), or at 2 h after surgery ( SMD=0.05, 95% CI -0.59-0.68, P=0.880) between two groups.There were no significant differences in the incidence of agitation during recovery ( RR=0.71, 95% CI 0.44-1.14, P=0.150) between two groups.There were no significant differences in the time of first urination ( MD=-84.52, 95% CI -195.72-26.69, P=0.140) between two groups.There were no significant differences in the incidence of postoperative nausea and vomiting ( RR=0.56, 95% CI 0.29-1.07, P=0.080) between two groups. Conclusions:DPNB and CB provide similar postoperative analgesic efficacy, but DPNB can prevent the occurrence of postoperative motor block, which is helpful for the postoperative rehabilitation in the pediatric patients undergoing penile surgery with general anesthesia.
ABSTRACT
Objective:To investigate the repair method and curative effect of iatrogenic penis skin necrosis of varying degrees.Methods:From June 2016 to December 2018, a total of 20 patients with varying degrees of iatrogenic penis skin necrosis were treated in our center. According to the area of the necrotic skin of penis, different treatment methods were selected: 2 patients with change dressing; 9 patients with relaxation suture; 7 patients with scrotal skin flap based on one side anterior scrotal artery; 2 patients with penile embedded in scrotum and secondary repair.Results:All patients were cured, there was no infection and flap necrosis. All of the patients were satisfied with the appearance of the penis, the flaps of anterior scrotal artery flap and scrotal pedicle embedding the penis survived well and the penis erectile function was not affected during the follow-up for 6 to 12 months.Conclusions:For patients of varying degrees of iatrogenic penis skin necrosis, individualized treatment should be adopted, which can effectively repair the penile defects and achieve satisfactory effect.
ABSTRACT
Objective To investigate the efficacy of preemptive analgesiawith ultrasound-guided modified dorsal penile nerve block combined ketorolac tromethamine for circumcision in pediatric patients.Methods Forty-five pediatric patients with ASA grade Ⅰ undergoing elective circumcision were randomly divided into 3 groups (n=15 each).The same intravenous compound anesthesia was used in the three groups.The pediatric patients underwent ultrasound-guided modified dorsal penile nerve block with a mixture of 0.1 ml/kg of 0.2% ropivacaine and 0.8% lidocaine before operation in group A and group B.The pediatric patients were given ketorolac tromethamine 1 mg/kg intramuscular injection before operation in group A and group C.The total consumption of propfol and sufentanil, occurrence of intraoperative body movement and respiratory depression, emergence time, time from waking up to going out of PACU and adverse reactions such as postoperative agitation, nausea, vomiting and pruritus were aslo recorded.The requirement for postoperative paracetamol suppositories was recorded.Results Compared with group C, the total consumption of propfol and sufentanil were significantly decreased, incidence of body movement andrespiratory depression were significantly decreased, the emergence time and time from waking up to going out of PACU was significantly shortened, requirement for paracetamol suppositories were significantly decreased in group A and group B(P<0.05).Compared with group B, incidence of requirement for paracetamol suppositories was significantly decreased in group A (P<0.05).No pediatric patients developed postoperative nausea, vomiting, pruritus and incidence of emergence agitation had no statistical difference in the three groups.Conclusion Preemptive analgesia with ultrasound-guided modified dorsal penile nerve block combined ketorolac tromethamine is safe and effective when used for circumcision in pediatric patients, and it has good efficacy of postoperative analgesia.
ABSTRACT
BACKGROUND: Circumcision is a painful intervention frequently performed in pediatric surgery. We aim to compare the efficacy of caudal block versus dorsal penile block (DPNB) under general anesthesia for children undergoing circumcision. METHODS: This study was performed between July 1, 2009 and October 16, 2009. Fifty male children American Society of Anesthesiolgists physical status classification I, aged between 3 and 12 were included in this randomized, prospective, comparative study. Anesthetic techniques were standardized for all children. Patients were randomized into 2 groups. Using 0.25% 0.5 ml/kg levobupivacain, we performed DPNB for Group 1 and caudal block for Group 2. Postoperative analgesia was evaluated for six hours with the Flacc Pain Scale for five categories; (F) Face, (L) Legs, (A) Activity, (C) Cry, and (C) Consolability. For every child, supplemental analgesic amounts, times, and probable local or systemic complications were recorded. RESULTS: No significant difference between the groups (P > 0.05) was found in mean age, body weight, anesthesia duration, FLACC pain, and sedation scores (P > 0.05). However, on subsequent measurements, a significant decrease of pain and sedation scores was noted in both the DPNB group and the caudal block group (P < 0.001). No major complication was found when using either technique. CONCLUSIONS: DPNB and caudal block provided similar postoperative analgesic effects without major complications for children under general anesthesia.

@#Voiding dysfunction is a serious complication after spinal cord injury.Now we have no effective treatment to deal with it,related operations mainly belong to reconstructive methods without long-term certain results.Neuromodulation,as a kind of way to suppress overactive detrusor,supposes to be an effective method.This paper would discuss its origin,application of dorsal penile nerve modulation and its candidate mechanism to certify the feasibility of neuromodulation on spinal cord injury patients.
ABSTRACT
OBJECTIVE: To investigate the immediate effect of dorsal penile nerve (DPN) stimulation on detrusor pressure (Pdet) and blood pressure (BP) during hyper-reflexic contractions of the bladder in patients with cervical spinal cord injury (SCI). METHOD: The subjects were eight male patients with cervical SCI who had symptoms of autonomic dysreflexia. During water-cystometry, BP was monitored using an intra-arterial catheter into the radial artery, and was recorded simultaneously with the Pdet. Electrical stimulation was applied to the DPN, using surface electrodes each time a bladder contraction was detected. Baseline BP and BP at the first and the last hyper-reflexic contractions of bladder were measured with Pdet, respectively. RESULTS: As Pdet increased, the BP increased in all cases. The reflex contractions of the bladder were effectively suppressed by DPN stimulation, and as the Pdet decreased during stimulation, radial arterial pressure also decreased immediately and significantly. CONCLUSION: DPN stimulation can lower both Pdet and the elevated BP.

OBJECTIVE: To evaluate the inhibition effects of hyper-reflexic detrusor activity by sacral afferent nerve stimulation in spinal cord injury (SCI) patients. METHOD: The subjects were thirteen patients with SCI who had symptoms of urinary incontinence, because of hyper-reflexic bladder contractions. According to the level and severity of injury, the patients were divided into groups of tetraplegia/paraplegia and complete/incomplete. We applied dorsal penile nerve (DPN) stimulation using portable stimulator during the continuous bladder filling. Stimulation parameters were biphasic rectangular pulses of 25 Hz frequency, 250 microseconds pulse width. Stimulation intensity was twice the threshold of pudendo-anal reflex. The one minute stimulation was repeated to every reflex contraction during the cystometry. Immediate suppressive effect of DPN was analyzed. RESULTS: Of 13 patients who had a reflex bladder, hyper-reflexic detrusor contractions were suppressed effectively in 12 by DPN stimulation. The suppressive effect in groups of level and severity was not statistically significant. CONCLUSION: DPN stimulation for inhibition of hyper-reflexic bladder contraction is an adjunctive method of incontinence management in SCI patients of different level and severity.
