Bilateral pudendal nerves block for postoperative analgesia with 0. II ; Carolina Beato, M. Hemorrhoidectomy may be performed dle several anesthetic techniques and in outpatient regimen.

Postoperative pain pudenddo severe and may delay discharge. This study aimed at evaluating bilateral pundendal nerves block for post- hemorrhoidectomy analgesia.

Bilateral pundendal nerves block with 0. R25 bupivacaine was performed with nerve stimulator in 35 patients submitted to hemorrhoidectomy under spinal anesthesia. Evaluated parameters were pain severity, duration of analgesia, demand analgesia and possible technique-related complications.

Data were evaluated 6, 12, 18, 24 and 30 hours after surgery completion. Successful pudendal nerves stimulation was achieved in all patients. There has been no severe pain in all evaluated moments. At 12 hours after blockade, all patients had perineal anesthesia; pudenro 18 hours, 17 patients and at 24 hours, 10 patients still presented perineal anesthesia. Postoperative analgesia was optimal for 18 patients; satisfactory, for 5 patients; and unsatisfactory, for 7 patients. Mean analgesic duration was There were no changes in blood pressure, heart rate, no nausea and vomiting were observed.

All patients had spontaneous micturition. No local anesthetic-related local or systemic complications were observed. Technique was considered excellent by 27 patients and only 3 male patients considered it satisfactory due to penile anesthesia.

Bilateral pudendal nerves block oriented by nerve stimulator provides excellent analgesia with low need for opioids, without local or systemic complications and without urinary retention. Controlled studies might be able to show whether this should be the first analgesic option for hemorrhoidectomies.

Perineal anesthesia lasting El dolor pos-operatorio es intenso y puede atrasar el retorno para el hogar.

Hemorrhoidal diseases are common throughout the world and are symptomatic in 4. Among all treatments for hemorrhoidal diseases, surgical resection seems to be the best to eliminate symptoms and improve quality of life 3. However, severe postoperative pain may prolong hospital stay 4. Postoperative pain is a major outpatient regimen problem 5. Several analgesic methods have been proposed for post-hemorrhoidectomy pain relief, such as subcutaneous morphine with infusion pump 7transcutaneous electric stimulation 8dexametazone 9perianal infiltration with bupivacaine 10posterior perineal block 11 and of the ischiorectal fossa The pudendal nerve is formed by posterior S 2S 3 and S 4 branches and is divided in four branches: In theory, pudendal nerve block may provide perineal analgesia or anesthesia being often used by surgeons and obstetricians.

Peripheral nerve stimulator, which is an excellent teaching method for regional anesthesia, helps the anesthesiologist in this type of blockade due to location monitored by perineal muscles contracture. Different animal and human studies have shown that levogyrous local anesthetics are less toxic for central nervous and cardiovascular systems as compared to racemic or dextrogyrous bupivacaine, with intrinsic ability to promote vasoconstriction and less intense motor block 14, Authors concluded suggesting that S R25 is a safer alternative as compared to racemic bupivacaine due to lower toxicity This study aimed at evaluating post-hemorrhoidectomy analgesia with 0.


R25 bupivacaine bilaterally injected in pudendal nerves located with the aid of electrical stimulation. Spinal anesthesia was induced in the left lateral position in L 3 -L 4 interspace, by the paramedial route with 27G Quincke needle B. Monitoring consisted of noninvasive blood pressure, heart rate and pulse oximetry. Patients were not premedicated. Minimum intraoperative fluids were administered, always below mL. Bilateral pudendal nerves block was performed at surgery completion with patients in lithotomy position and under spinal anesthesia effect.

Meaning of “pudendo” in the Spanish dictionary

The needle access was transperineal and medial to ischial tuberosity on both sides, using beveled insulated needle with mm B. Braun Melsungen AG, 21G 0. Braun Melsungen AG set to release a square pulsatile current of 1 mA, with 2 Hz frequency, perpendicularly inserted to a depth of approximately 7 cm, trying to obtain anal sphincter contraction.

After perineal contraction, 20 mL of 0. R25 were injected in each side. Patients were followed for nerviio hours in the hospital and then at 12, 18, 24 and 30 fel by telephone when they were questioned about pain severity, which was classified as: Patients were also asked whether the operated region was insensitive anesthesia.

Pain at first evacuation was evaluated with the same scale and time between blockade and first evacuation was recorded. Patients were asked about postoperative analgesia, which should be classified as excellent, satisfactory or poor.

Oral tramadol was prescribed in case of pain. Analgesia was classified as optimal if no analgesic tramadol was needed; satisfactory one dose and unsatisfactory two or more doses. Demographics data, painless period, pain severity, oral analgesic frequency, total doses pidendo complications, such as urinary retention, were evaluated. Qualitative variables presence of pain, pain severity, pain at first evacuation, blockade at 6, 12, 18, 24 and 30 hours and level of satisfaction were evaluated with regard to gender by Fisher’s Exact test.

Quantitative variables compared with regard to time were analyzed by paired t test, and with regard to gender by t test for nerfio samples, assuming different variances. Demographics data are shown in table I. Spinal anesthesia was satisfactory for all patients and no patient needed complementation with general anesthesia.

Both pudendal bolqueo were successfully stimulated in all patients. There were no changes in blood pressure and heart rate, there were no postoperative nausea or vomiting. No local or systemic complications were related to local anesthetics. Pain severity in the first 30 postoperative hours is shown in table II and there has been no maximum pain severe throughout the study.

All patients presented perineal anesthesia 12 hours after blockade. At 18 hours, 22 patients; at 24 hours, 12 patients and at 30 hours, no patient presented perineal anesthesia Table II. At 6 and 12 postoperative hours no female has referred mild pain and four males boqueo referred it remaining males did nor refer painshowing a higher incidence of pain in males in these moments. At 18 hours, one female has referred mild pain as compared to 10 males, with a high incidence of pain among males.

At 24 hours, two females have referred nrrvio pain and no one has referred mild pain, while among males there has been one case of moderate and nine cases of mild pain, showing a higher incidence of mild or moderate pain among males. Two females have referred pain at first postoperative evacuation as compared to eight males. At 12 post-blockade hours, all patients had perineal anesthesia; at 18 hours, 22 patients, being 15 females and 7 males, indicating lower probability of blockade for males in this period.


At 24 hours, blockade persisted in 12 patients, being 5 females and 7 males, with no statistically significant difference in this moment. Analgesia duration was 15 to 20 hours in 10 patients; 21 to 25 hours, in 14 patients; 26 to 30 hours, in 10 patients; and more than 31 hours in 1 patient, with mean duration of Postoperative analgesia was optimal for 23 patients; satisfactory, for 5 patients, and unsatisfactory, for seven patients. There has been no need for postoperative analgesia in 23 patients.

First evacuation was approximately 30 hours after bilateral pudendal nerves block; 10 patients have referred pain at evacuation, while 25 patients have not.

Analgesic technique was considered excellent by 32 patients and only 3 male patients have considered it satisfactory due to penile anesthesia. External hemorrhoidal thrombosis is probably one of the most common anorectal emergency diagnoses and surgery is the treatment, of choice.

In our study, postoperative analgesia with bilateral pudendal nerves block under spinal anesthesia has resulted in mean phdendo Hemorrhoidectomy is a short procedure, however extremely painful, and few studies are directed toward postoperative analgesia Major pain factors are related to surgical procedure.

Milligan-Morgan technique open seems to be much more painful as compared to Reis Neto semi-open hemorrhoidectomy or even to the closed procedure Some authors use posterior perineal block for anesthesia and postoperative analgesia.

There are several variants of initial descriptions 11,19, Differences refer to technical details, equipment and anesthetic drugs. It is also necessary to differentiate pararectal infiltration from perineal block.

Pararectal or perineal infiltration is a superficial posterior perineal block bloqeuo used as single technique Our study has used bilateral pudendal nerves block oriented by nerve stimulator, resulting in perineal anesthesia for It was not our proposal to evaluate differences in the incidence of pain between genders.

However, there has been higher incidence of pain among males as compared to females in all evaluated periods and during first evacuation. These data shall be the object of further studies. All anesthetic drugs have already been used for posterior perineal block: Lidocaine or mepivacaine administered to patients have induced analgesia for 5 hours in One to three mL of 0. The injection of 20 mL of 0. R25 in each pudendal nerve has bolqueo mean A different publication 16 evaluating the same solution with twice the concentration 0.

Spinal anesthesia leads to clinical vesical function disorders due to the interruption of micturition reflex. Bladder function remains imperfect until the blockade has regressed to the 3 rd sacral segment in all patients With long lasting anesthetics, accumulated volume may exceed the cystometric capacity of the bladder This shows that bilateral pudendal nerves block has resulted in perineal anesthesia bloquwo approximately 20 hours without preventing spontaneous micturition.

This pilot study has used bilateral pudendal nerves block with the aid of peripheral nerve stimulator to control postoperative pain of patients submitted to hemorrhoidectomy under spinal anesthesia. The study has its limitations because analgesia results were not compared to a different method.
