This paper aimed to study the application of local anesthetics combined with transversus abdominis plane (TAP) block in gynecological laparoscopy (GLS) surgery during perioperative period under the guidance of ultrasound image enhanced by the wavelet transform image enhancement (WTIE) algorithm. 56 patients who underwent GLS surgery in hospital were selected and classified as the infiltrating group and block group. The puncture needle was guided by ultrasound images under WTIE algorithm, and 0.375% ropivacaine was adopted to block TAP. The results showed that the dosage of propofol in the infiltrating group (313.23 ± 19.67 mg) was remarkably inferior to the infiltrating group (377.67 ± 21.56 mg) P < 0.05 . The hospitalization time of patients in the infiltrating group (2.14 ± 0.18 days) was obviously shorter than that of the infiltrating group (3.23 ± 0.27 days) P < 0.05 . 3 h, 6 h, and 12 h after the operation, the visual analogue scores (3.82 ± 1.58 points, 2.97 ± 1.53 points, and 1.38 ± 0.57 points) of the patients in the infiltration group were considerably higher than the infiltrating group (2.31 ± 1.46 points, 1.06 ± 1.28 points, and 0.95 ± 0.43 points) P < 0.05 . 3 h, 6 h, and 12 h after the operation, the number of patients in the infiltrating group who used tramadol for salvage analgesia (2 cases, 1 case, and 1 case) was notably less than that in the infiltration group (9 cases, 7 cases, and 3 cases) P < 0.05 . In short, local anesthetics combined with TAP block can reduce postoperative VAS score and postoperative nausea and vomiting (PONV) score, which also reduced the incidence of postoperative analgesia.

Abstract Background Although regional techniques have been suggested more in order to provide postoperative analgesia in inguinal hernia repairs, the ideal method is still controversial. The aim of this study was to evaluate the effect of preemptive transversus abdominis plane (TAP) block, local anesthetic infiltration (LAI) and intravenous dexketoprofen (IVD) on postoperative pain in inguinal hernia repairs. Methods This prospective study included 120 patients with American Society of Anesthesiologists status 1-3 between 18-75 years of age who undergoing elective inguinal hernia surgery under spinal anesthesia. The patients were allocated into three groups: USG-guided TAP block (Group 1, n = 40), USG-guided LAI (Group 2, n = 40) and IVD (Group 3, n = 40) before surgical incision. The mean of tramadol consumption, number of patients in requiring rescue analgesics, duration of postoperative analgesia and complications were recorded for 24 hours postoperatively. VAS scores were evaluated at the 30 minute, 1, 2, 4, 8, 12, 16 and 24th hours. Results There was no significant difference between the postoperative mean tramadol consumption [Group 1: 22.5 mg; Group 2: 20 mg; Group 3: 27.5 (p 0.833)]. The number of patients requiring rescue analgesics was statistically similar (p 0.787). VAS scores at 30. min, 1, 2, 4, 8 and 12 hours were statistically lower in Group 1 than in the other groups (p 0.003, 007, 0013, 0049, 0015, 0021). VAS scores at 30. min and 2. h were lower in Group 1 than Group 2 (p 0.049, 0.037). İn addition, VAS scores at 30 min, 1, 2, 8 and 12 hours were lower in Group 1 than in Group 3 (p 0.003, 0.006, 0.021, 0.017, 0.016). VAS scores at all hours were statistically similar between Group 2 and Group 3. Conclusion This study demonsrated that preemptive transversus abdominis plane block, local anesthetic infiltration or iv dexketoprofen for postoperative analgesia in inguinal hernia repairs had similar effects on postoperative tramadol consumption and number of requiring rescue analgesic patients. However, TAP block provides lower VAS values and excellent analgesia in more patients in the first 24 hours postoperatively.

Background. How to effectively control the postoperative pain of patients is extremely important to clinicians. Transversus abdominis plane (TAP) block is a novel analgesic method reported to greatly decrease postoperative pain. However, in many areas, there still exists a phenomenon of surgeons using wound infiltration (WI) with conventional local anesthetics (not liposome anesthetics) as the main means to decrease postoperative pain because of traditional wisdom or convenience. Here, we compared the analgesic effectiveness of the two different methods to determine which method is more suitable for adult patients. Materials and methods. A systematic review and meta-analysis of randomized controlled trials (RCTs) comparing TAP block and WI without liposome anesthetics in adult patients were performed. Frequently used databases were extensively searched. The main outcomes were postoperative pain scores in different situations (at rest or during movement) and the time until the first use of rescue analgesics. The secondary outcomes were postoperative nausea and vomiting (PONV) incidence and patient satisfaction scores. Results. Fifteen studies with 983 participants met the inclusion criteria and were included in the present study. The heterogeneity in the final analysis regarding the pain score was low to moderate. The major results of the sensitivity analysis were stable. WI had the same analgesic effect as TAP block only at the one-hour postoperative time point (mean difference=−0.32, 95% confidence interval (-0.87, 0.24), P=0.26) and was associated with a shorter time until the first rescue analgesic and poorer patient satisfaction. Conclusion. TAP block results in a more effective and steady analgesic effect than WI with conventional local anesthetics in adult patients from the early postoperative period and obtains higher patient satisfaction.

Interventional Catheterization

Interventional catheterization can help patients to accurately assess the condition, early diagnosis and intervention. Confirming the location of catheter by ultrasound has the advantages of real-time imaging, non-invasive, radiative, fast and convenient. Due to speckle noise and similar acoustic impedance, ultrasound images are not clear. In this paper an ultrasonic image processing algorithm based on wavelet transform and fuzzy theory is proposed. First, logarithmic transformation of ultrasound images is used to convert multiplicative noise into additive noise. Then the wavelet coefficients of the image are obtained by multiscale wavelet transform. The high frequency wavelet coefficients of the image are denoised by thresholding, and the low-frequency wavelet coefficients of the image are processed by fuzzy enhancement. Finally, the processed image is obtained through wavelet reconstruction and exponential transformation. Experiments show that this proposed method can effectively improve the visual effect of images.

Abstract Background Patients undergoing Open Appendectomy experience pain postoperatively, requiring a multimodal approach to analgesia. The transversus abdominis plane (TAP) block seems to be an ideal approach. This block may be achieved using bupivacaine with adjuvants such as magnesium sulfate, which we were used in this study. Aim of the Work to detect the efficacy and safety of magnesium sulphate as an adjuvant to the analgesia offered by local anesthetic in ultrasound guided TAP block in patients undergoing open appendectomy. Patients and Methods A prospective double blinded randomized controlled trial was conducted on 60 patients undergoing open appendectomy at Ain Shams University Hospital, Cairo, Egypt. Results Our study concluded that co administration of 500mg MgSo4 to 0.5 % bupivacaine in US guided TAP block lead to: Significant decrease in VAS pain score especially at 4hrs, 6hrs and 12hrs,1st rescue dose of nalbuphine was delayed. And number of patients require rescue doses of nalbuphine in 1st 4 hrs, while only 2 patients require rescue doses of nalbuphine between 4&6 hrs.4 patients require rescue doses of nalbuphine between 6&12 hrs, while 26 patients require rescue doses of nalubuphine between 12&24hrs. we also cocluded that there were a significant decrease in HR and MABP especially at 4hrs and 6 hrs postoperative,. Conclusion MgSO4 as an adjuvant to bupivacaine in Ultra-sounded guided TAP block reduces post-operative pain scores, prolong the duration of analgesia and decreases demand for rescue analgesics.

Aim. This study aims to compare the postoperative analgesia between preoperative and postoperative ultrasound-guided transversus abdominis plane (TAP) blocks for different durations of laparoscopic gynecological surgery. Methods. A total of 120 patients, ASA I-III, 18–65 years of age, were divided randomly into 2 groups: preoperative TAP group (pre-TAP group) and postoperative TAP group (post-TAP group). Patients in the pre-TAP group (n = 60) and post-TAP group (n = 60) received bilateral TAP blocks of 0.375% ropivacaine, 40 mL, preoperatively and postoperatively, respectively. Duration of surgery, postoperative pain score, consumption of analgesics, and postoperative nausea and vomiting (PONV) during the first 24 h postoperatively were recorded. Results. For all the patients in the two groups, similar analgesia was obtained with no statistical difference. The same results were found in duration of surgery <180 min. Meanwhile, patients undergoing surgery >180 min in the post-TAP group obtained lower postoperative pain score, lower analgesics consumption, and higher satisfaction score than those in the pre-TAP group. Conclusion. Postoperative TAP block could offer better postoperative analgesia than preoperative TAP block for patients undergoing surgery >180 min. No difference was found in analgesia effect between preoperative TAP block and postoperative TAP block for patients undergoing surgery <180 min.

Monitoring And Early Warning

Norovirus monitoring and early warning can be used for diagnosis without etiological testing, and the treatment of this disease does not require the antibiotics. It often occurs in preschool children and affects their growth and development, so the coping measures for this disease are more prevention than treatment. In this study, the clinical data of 2133 children with diarrhea were collected. Based on the artificial intelligence (AI) algorithm of wavelet transform, a related model for data mining and processing of children’s intestinal ultrasound images and stool specimens was constructed. Then, the norovirus infection trend was warned based on the wavelet analysis algorithm model. The results showed that the intestinal ultrasound image processed by the wavelet transform algorithm was clearer. The positive detection rate of norovirus in children with clinical diarrhea was as high as 59%, and the children had different degrees of body damage, of which the probability of compensatory metabolic acidosis was the highest. The epidemiological analysis found that children with norovirus infection were mainly concentrated in the age group under 2 years old and over 5 years old and showed a peak of infection in December. In summary, the intelligent algorithm based on wavelet transform can realize the noise reduction of intestinal ultrasound, and it should protect children with susceptible age and susceptible seasons to reduce the clinical infection rate of norovirus.

Objective To compare patients that received intravenous (i.v.) analgesics with those that received transversus abdominis plane (TAP) block for pain relief after laparoscopic cholecystectomy. Methods This retrospective study enrolled patients that had undergone laparoscopic cholecystectomy and divided them into two groups: the i.v. analgesic group (controls; group A) and the TAP block group (group T). Data retrieved from the medical records included postoperative visual analogue scale (VAS) pain scores, duration of intensive care unit (ICU) stay, total hospital stay, additional analgesic requirements and the occurrence of nausea and vomiting. Results A total of 515 patients were included (group A, n = 247; group T, n = 268). Postoperative VAS pain scores at 0, 2, 4 and 6 h and the need for additional analgesics were significantly lower in group T than in group A. Postoperative VAS pain scores at 12 and 24 h were significantly higher in group T than in group A. Postoperative nausea and vomiting were significantly lower in group T than in group A. The rate of ICU admission in group T was significantly lower than in group A. Conclusions Effective postoperative analgesia can be achieved with TAP block and undesirable effects can be reduced.

Purpose of Review. Transversus abdominis plane (TAP) block is a regional technique for analgesia of the anterolateral abdominal wall. This review highlights the nomenclature system and recent advances in TAP block techniques and proposes directions for future research.Recent Findings. Ultrasound guidance is now considered the gold standard in TAP blocks. It is easy to acquire ultrasound images; it can be used in many surgeries involving the anterolateral abdominal wall. However, the efficacy of ultrasound-guided TAP blocks is not consistent, which might be due to the use of different approaches. The choice of technique influences the involved area and block duration. To investigate the actual analgesic effects of TAP blocks, we unified the nomenclature system and clarified the definition of each technique. Although a single-shot TAP block is limited in duration, it is still the candidate of the analgesic standard for abdominal wall surgery because the use of the catheter technique and liposomal bupivacaine may overcome this limitation.Summary. Ultrasound-guided TAP blocks are commonly used. With the unified nomenclature and the development of catheter technique and/or liposomal local anesthetics, TAP blocks can be applied more appropriately to achieve better pain control.

Effective Pain Relief

Postoperative analgesia is an important aspect of anesthesia care since pain problems affect both physical and mental derangement, resulting in delayed recovery. Transversus abdominis plane block (TAP block) can be performed in the abdominal wall area using ultrasound-guided technique. The TAP block is a peripheral nerve block designed to anesthetize the nerves supplying the anterior abdominal wall. Nowadays, the TAP block could also be used to reduce the need for postoperative opioid use, to extend the period of first analgesia request, and to provide more effective pain relief while decreasing opioid related side effects such as sedation and postoperative nausea and vomiting. Realizing the need to create an innovation, Ramathibodi Hospital anesthesia team has introduced the RAMA TAP block sheet, which is a transparent plastic sheet with 2 square-sided holes. The RAMA TAP block sheet is designed to facilitate anesthesiologist during TAP block procedure and reduce contamination risk from gauzes in surgical area. This innovation could potentially allow the anesthesiologist to visualize both sides of abdominal walls as well as the midline of abdomen clearly so that a good injection site with local anesthetic to skin can be located. The RAMA TAP block sheet is an inexpensive, practical and highly efficient invention that could be sterilized.
