Increase In Intra-abdominal Pressure Research Articles

The relationship between positive end-expiratory pressure (PEEP) and intra-abdominal pressure (IAP) in mechanically ventilated patients: A prospective observational study.

Positive end-expiratory pressure is a crucial mechanical breathing parameter. Intra-abdominal hypertension is well defined as a sustained increase in the intra-abdominal pressure ≥12 mmHg. There are still controversies about mechanical ventilation's effect and use of positive end-expiratory pressure on intra-abdominal pressure. We aimed to delineate the relationship between positive end-expiratory pressure and intra-abdominal pressure in mechanically ventilated patients admitted to the intensive care units of a large tertiary hospital in Upper Egypt. This study was a prospective observational study. The study was conducted at a university hospital from October 2023 to February 2024. The enrolled adult patients were allocated into two groups based on their positive end-expiratory pressure: group I, low pressure (<8 cm H2O) and group II, high pressure (8-10 cm H2O). A total of 120 patients were enrolled, 60 patients in each group. The most commonly encountered diagnoses were pneumonia (32/120, 26.7%) and acute respiratory distress syndrome (ARDS) (31/120, 25.8%), respectively. There was a significant difference between the intra-abdominal pressure mean values of the two patient groups, 18.9 ± 3.3 versus 24.4 ± 5.9 mmHg in the group of low versus high pressure (correlation value of .454, p < .001), respectively. There were highly significant correlations between intra-abdominal pressure categories and the patient groups (correlation value of .495, p < .001). There were 24 (40%) versus 0 (0%) patients of high pressure versus low pressure within the category IV group of intra-abdominal hypertension (>25 mmHg). We observed a significant relationship between positive end-expiratory pressure and intra-abdominal pressure in mechanically ventilated patients. The patient group with high pressure had higher mean values compared with the group with low pressure. The study highlights the importance of closely monitoring intra-abdominal pressure in mechanically ventilated patients who receive positive end-expiratory pressure. Further studies are warranted. The relationship between positive end-expiratory pressure and intra-abdominal pressure is an essential issue in daily critical care nursing clinical practice. Considering the occurrence of multiple organ dysfunction as a result of a non-detected increase in intra-abdominal pressure, critical care nurses should pay attention to measuring this pressure to maintain intra-abdominal pressures that are safe for mechanically ventilated and critically ill intensive care unit patients, thereby preventing these undue effects.

The Effect of Increased Intra-Abdominal Pressure on Hemodynamics in Laparoscopic Cholecystectomy-The Experience of a Single Centre.

Laparoscopic cholecystectomy is characterized by reduced postoperative pain, shorter hospital stays, rapid return to preoperative physical activity, and less psychological impact on the patient. During laparoscopic cholecystectomy, the intra-abdominal insufflation of carbon dioxide with secondary increase in intra-abdominal pressure can cause important hemodynamic consequences, like decreased cardiac output and blood pressure, as well as compensatory increase in heart rate. The purpose of this study is to evaluate changes in cardiovascular parameters during general anesthesia in patients undergoing laparoscopic cholecystectomy. Retrospective data from 342 patients with cholecystectomy for cholelithiasis performed at Railway Hospital Galati, Romania, were reviewed. All patients received the same intraoperative anesthetics. Female patients were 85.7% (n = 293). More than half of the patients, 53.51% (n = 183), were 40-59 years old, and only 16.37% (n = 56) were under 40 years old. Patients with a normal body mass index (BMI) represented 45.6% (n = 156), 33.3% (n = 114) were underweight, and 12% (n = 42) had grade 1 obesity (BMI 25-29.9 kg/m2). The minimum intraoperative blood pressure correlated with patient gender (p 0.015 < 0.005), with men having a higher blood pressure than women (p 0.006 < 0.05), and for BMI, a higher BMI was associated with elevated blood pressure (p 0.025 < 0.05). Older age correlated with an increased maximum intraoperative blood pressure (p < 0.001 < 0.05) and with maximum intraoperative heart rate (p 0.015 < 0.05). Patients undergoing laparoscopic cholecystectomy experienced significant hemodynamic changes with pneumoperitoneum, but this type of surgical intervention was safe for patients regardless of their age.

Application of the Valsalva maneuver in medicine and sport

The Valsalva maneuver, named after Antonio Maria Valsalva, is one of the vagal maneuvers. It is defined as a forced expiration against a closed glottis, leading to an increase in intrathoracic and intra-abdominal pressure. Over the years it has become a subject of interest to many clinical researchers who have comprehensively studied its physiology and clinical significance. As a result, the application of the Valsalva maneuver has expanded to become a versatile technique applied across a wide range of medical specialties as a diagnostic and therapeutic tool. Additionally, it has found its use in sport among athletes. The aim of this article is to present the current state of knowledge about the clinical significance of the Valsalva maneuver and show that this simple physiological technique described in the 18th century remains a valuable tool in modern clinical practice and has found its use in sport. The review was based on chosen literature obtained from the PubMed electronic database, Google Scholar electronic database, and other scientific articles. Search terms included keywords listed below. Keywords: Valsalva maneuver; vagal maneuver; respiratory maneuver; autonomic system

Intra-abdominal pressure: a predictor of severity in acute pancreatitis

Background: Acute pancreatitis is a multisystem disease which has an unpredictable course. The major consequence of severe acute pancreatitis is usually intra-abdominal hypertension. So, abdominal compartment syndrome occurs with serve increase in intra-abdominal pressure (IAP) with organ failure. If conservative measures fail, some early interventional procedures have to be performed to reduce mortality in those patients. Methods: The ethics committee clearance was obtained. The study included 50 patients who were admitted in our institution with acute pancreatitis (diagnosed based on clinical, radiological, biochemical parameters) from December 2022 to August 2023. Intravesical route was used to measure IAP and it was performed by bladder catheterization using a Foley's catheter which was then connected with a three-way stopcock, which further attached with a water manometer and on that same day APACHE scores was calculated, compared and analyzed. Results: IAP was &gt;25 cm H2O in 48% of patients and 28% of patients developed MODS and they did not survive. The mean IAP among the survivors was 13.56 cm H2O and in non-survivors it was 24.94 cm H2O. Correlation studies between IAP &amp; the clinical severity of acute pancreatitis was significant (p&lt;0.05). Conclusions: IAP seems to be a simple, reliable and single mortality predictor and helps to assess organ failure in acute pancreatitis and it also well correlates with other pancreatic prognostic scores. It also serves as a selective prognostic marker in acute pancreatitis and found to have a direct correlation between IAP and clinical severity of acute pancreatitis.

Comparative evaluation of single versus double leg raise maneuver in high-resolution esophageal manometry.

The straight leg raise (SLR) maneuver, often performed during esophageal manometry, requires patients to lift their leg(s) to augment intraabdominal pressure (IAP). Diverse techniques have been applied for SLR. This study aimed to evaluate and compare the effects of SLR between single and double leg raises. During esophageal manometry, patients were asked to raise one leg, followed by elevating both legs. The efficacy of SLR for (1) detecting hiatal hernia, (2) increasing IAP, and (3) predicting gastroesophageal reflux disease (GERD) with intraesophageal pressure (IEP) was assessed. The value of change in impedance to indicate reflux during SLR in predicting esophageal acid exposure was investigated. The leg raise procedures were performed in 86 patients undergoing high-resolution esophageal manometry. Both the single and double leg raises exhibited a higher hiatal hernia detection rate compared to the landmark (p = 0.008 and 0.005, respectively). Double leg raise was more effective in raising IAP by >50% compared to single leg raise (100% vs. 65.1%, p < 0.001), increasing yield by 53.6%. The change in IAP showed a positive correlation with the change in IEP during double leg raise (r = 0.31; p = 0.004), higher than that for single leg raise (r = 0.23; p = 0.03). Lower intraesophageal impedance during SLR was associated with AET > 6% with double leg raise (1.5 kΩ vs. 2.5 kΩ, p = 0.04). Our study demonstrates the efficacy of both single and double leg raise maneuvers during HREMI in increasing hiatal hernia detection and possible value in predicting GERD. The double leg raise resulted in a higher rate of effective increase in IAP, potentially enabling more patients to undergo effective SLR during HREMI.

Kegel exercises with a guidebook for stress urinary incontinence treatment

BACKGROUND Stress urinary incontinence (SUI) is uncontrollable urine leakage when intra-abdominal pressure increases. Behavioral therapy with Kegel exercise is currently the best conservative management recommendation for treating SUI patients. This study aimed to investigate the success of supervised Kegel exercises using the Kegel exercises guidebook in women with SUI. METHODS This quasi-experimental study involved both groups being taught the same regiment of Kegel exercises, but the intervention group was given the Kegel exercises guidebook. After 12 weeks, the compliance, subjective, and objective success rates were evaluated through the patient’s notes, Urinary Distress Inventory-6, Incontinence Impact Questionnaire-7, perineometer, and pad test. RESULTS Patients with a higher level of education had lower compliance to Kegel exercises (p = 0.01; odds ratio [OR] 0.38; 0.18–0.79). No significant difference was observed in the subjective symptom improvement between the two groups. The intervention group had a significantly higher success rate based on objective success by analyzing the 1-hour pad test results. The intervention group was also more adherent (p&lt;0.001; OR 4.78; 2.51–9.0). CONCLUSIONS Patients who received the Kegel exercises guidebook were more compliant and more objectively successful than those who did not receive the manuals.

Cardiac Effects of Carbon Dioxide Pneumoperitoneum in Veterinary Laparoscopy for Dogs

Despite all of the advantages of laparoscopic surgery, there remain certain concerns. An increased intra-abdominal pressure (IAP) exerted by CO2 pneumoperitoneum has adverse effects on all organs and systems especially on the circularity system and cardiac function. To understand effect of IAP study was undertaken on twelve female mongrel dogs brought for laparoscopic ovariohysterectomy. All dogs were sedated with butorphanol, induced with propofol and maintenance of anesthesia was done with isoflurane. All dogs underwent a detailed systemic investigation protocol including echocardiographic examination. Physiological parameters such as rectal temperature decreased significantly throughout anaesthetic period and come to normal after complete recovery. Heart rate, pulse rate and respiratory rate was decreased significantly after induction of anaesthesia and increased after insufflation of CO2. Echocardiographic parameters like EF and CO were decreased significantly after induction of anaesthesia by 9% and 33% respectively and after insufflation of CO2 by 8% and 5% respectively. However, all other parameters (FS and SV) showed no significant changes. In conclusion, effects of CO2 pneumoperitoneum and anaesthesia on cardiac function are mild and of transient duration in healthy dogs.

Is There a Direct Effect Between the Plication of the Myoaponeurotic Layer and the Force of Inspiratory and Expiratory Muscles After Abdominoplasty?

Abdominoplasty may generate an increase in the intra-abdominal pressure (IAP) and consequently an alteration in the pulmonary ventilation. The purpose of this study was to evaluate the potential alterations in the maximal static inspiratory pressure (MIP) and maximal static expiratory pressure (MEP) after abdominoplasty. Thirty-three female patients, aged between 18 and 60, with type III/B Nahas abdominal deformity that underwent abdominoplasty with plication of the anterior rectus and external oblique aponeurosis were selected. The MIP and MEP were measured using a mouthpiece. This is a simple way to indirectly gauge inspiratory and expiratory muscle strength. Measurements were performed before surgery and on the 2nd, 7th, 15th, and 180th postoperative day. In addition, IAP was measured before abdominoplasty and after the placement of compression garment. The MIP and MEP were compared using analysis of variance, followed by the Bonferroni multiple comparison test pairing the different points in time. Paired Student's t test was used for comparing IAP measurements. Pearson's correlation test was used to compare MIP and MEP variations with IAP variation. Results were considered statistically significant when P ≤ 0.05. A decrease was observed in MEP on the 2nd day, with a return close to normal values on the 15th day. In opposition MIP had a surprisingly increase on the 15th postoperative day (129 cmH2O), normalizing 180 days after the operation. A leap in IAP values was revealed at the end of the surgical procedure. It was not possible to establish a positive correlation between the increase of IAP and the alterations of MIP and MEP. There is a decrease in maximum expiratory pressure on the very early postoperative day (2nd postoperative day) and an increase in maximum inspiratory pressure on the 15th postoperative day in patients who underwent abdominoplasty. There was no correlation between the IAP and maximum respiratory pressure variations, both inspiratory and expiratory.

Robotic Pediatric Urologic Surgery-Clinical Anesthetic Considerations: A Comprehensive Review.

Minimally invasive robotic approaches have become standard in many institutions over the last decade for various pediatric urological procedures. The anesthetic considerations for common laparoscopic and robotic-assisted surgeries are similar since both require the insufflation of CO2 to adequately visualize the operative area. However, few studies exist regarding anesthesia for robotic procedures in children. We hypothesized that pediatric patients undergoing robotic urologic surgeries would require specific anesthetic strategies, especially given the inherently longer durations of these procedures. This study aimed to evaluate anesthetic considerations, current robotic procedures, optimal patient positioning, and port placement for robotic-assisted surgery in pediatric patients. A comprehensive literature review of all published manuscripts from PubMed, EMBASE database, and Google Scholar was performed, focusing on robotic procedures involving pediatric patients, anesthesia for pediatric urology patients, and related topics from 1996 to 2023. Forty published manuscripts were identified and reviewed in depth. In pediatric cases, insufflation pressures and volumes are lower due to the laxity of the abdominal wall. However, the increase in intra-abdominal pressure and absorption of CO2 may result in disproportionate changes in cardiopulmonary function. Specific patient positioning for robotic approaches may further compound these physiological changes. Correct patient positioning is essential to facilitate surgery optimally and safely. Understanding the physiological changes that can occur during a pediatric patient's robotic urologic surgery allows for safer anesthesia management.

Combined Rupture of the Diaphragm and Urinary Bladder in Blunt Trauma Abdomen.

The authors examined a 25-year-old man with a combined rupture of the diaphragm and urinary bladder following blunt trauma to the abdomen. The presence of hematuria, suprapubic tenderness, and elevated serum urea and creatinine levels in this patient raised suspicion of urinary bladder rupture. Documentation of bowel gas shadows on the chest x-ray suggested underlying diaphragm injury. A computed tomogram of the thorax and abdomen confirmed the tear in the left hemidiaphragm with intrathoracic herniation of abdominal contents; however, it failed to detect the intraperitoneal urinary bladder rupture. Both the defects were identified and repaired during laparotomy. The sudden increase in intraabdominal pressure in blunt trauma to the abdomen often resulted in full-thickness tears of the diaphragm and the urinary bladder. Although radiological investigations were pivotal for assessing the damage to the internal organs, a methodical and thorough exploratory laparotomy was invaluable for successfully managing patients with blunt abdominal trauma.

The female urethral closure mechanism during physical stress.

The closure of the urethra under the condition of stress is the result of a reflex contraction of the urethral rhabdosphincter and pelvic floor muscles. This is likely induced by activity of the abdominal muscles due to a sudden increase in abdominal pressure. This reflex contraction with an increase of urethral pressure occurs a few milliseconds before an increase in intraabdominal pressure. The urethral pressure increase during stress is only possible with fixation of the urethra by the pubourethral ligaments (PUL), facilitating urethral kinking. The highest and most important increase in pressure and resistance occurs in the distal urethra due to this kinking of the urethra.

Influence of intra-abdominal pressure on ventilatory mechanical power delivery and respiratory driving pressure during laparoscopic cholecystectomy: A prospective cohort study.

Pneumoperitoneum creation for laparoscopic surgery increases the intraabdominal pressure and causes alveolar atelectasis. We investigated the influence of an increase in intra-abdominal pressure (IAP) on ventilatory mechanical power (MP) delivery during pneumoperitoneum creation for laparoscopic cholecystectomy. In a prospective cohort design, we enrolled 42 patients undergoing laparoscopic cholecystectomy. During pneumoperitoneum creation, the IAP was sequentially raised to three predefined IAP levels (8, 11 and 14 mmHg), keeping identical ventilatory settings (timepoints T1, T2, and T3). After that, positive end-expiratory pressure (PEEP) was sequentially raised from 5 to 8 to 11 cmH2O (timepoint T4 and T5). The primary outcome included ventilatory MP delivery at each timepoint. Other variables included respiratory driving pressure (DP), airway resistance (AR), and respiratory compliance (RC). The MP increased linearly with a rise in IAP from T1 to T3 (r = 0.71, P < 0.001); the MP increased by 0.19 per unit rise in IAP (effect size 0.90, P < 0.001). A similar positive correlation was also observed between DP and IAP from T1 to T3 (r = 0.73, P < 0.001); the DP increased by 0.72 per unit rise in IAP (effect size 0.89, P < 0.001). The MP increased significantly on increasing PEEP from T3 to T5, while the DP decreased concomitantly (P < 0.001). The AR increased significantly from T1 to T3, while RC decreased concomitantly; vice-versa was observed at T4 and T5 (P < 0.001). The ventilatory MP delivery rises linearly with an increase in IAP. Targeting an IAP-guided MP level could be an attractive approach to minimize lung injury.

Morphometric evaluation of the linea alba in fresh corpses

PurposeDiastasis recti abdominis is an increase in the distance between the medial borders of the two rectus muscles. It is most often triggered after intra-abdominal pressure increases, such as postpartum or in obesity. Most publications are based on radiological studies or are done in certain subgroups, without unanimous reference values of the distance between the rectus abdominis or standardization. MethodsForty-one cadavers were studied. Exclusion criteria: signs of abdominal trauma, major burns, presence of scar from previous abdominal surgery, clinical signs of abdominal hernia, and identification of hernia during cadaver dissection. Linea alba (LA) length, width, and thickness were measured with a flexible tape measure and digital caliper. Anatomical landmarks were established, and subdivisions were described based on them to compare the cadavers. ResultsSex and age had little effect on LA width, thickness, or length. Obesity (compared to normal weight) was the only variable that promoted an increase in the LA width (p < 0.01). The supraumbilical length varied with the total height of the evaluated cadavers (p < 0.01), but the infraumbilical length did not (p = 0.11). ConclusionThe general statistical results of this study, regarding the evaluation of LA measurements in cadavers, showed that ethnicity, sex, and age have little effect on the width, thickness, or length of the LA. LA width differed significantly with abdominal circumference.

Meckel's Diverticulum Injuries after Blunt Trauma.

Background: The complications associated with Meckel's diverticulum (MD) are well-known. However, blunt injuries regarding MD have not been widely described in the literature. This was the reason for undertaking research on MD lesions. Materials and Methods: The materials consisted of 28 cases of damage to MD after blunt trauma published during the years 1921-2022. The collected data were subjected to statistical analysis. Results: The following MD injuries have been identified, starting with the most common isolated perforation of MD, bleeding from the area of MD, perforation of MD with concomitant tearing of the mesentery intestines and bleeding, intussusception of MD, and intramural hematoma of MD with adjacent mesenteric hematoma. Most injuries were caused by a traffic accident, followed by sports, accidents at work, and then violence. Almost all the cases (27) involved men. Several possible mechanisms may contribute to post-traumatic damage to MD. First of all, they are associated with abdominal compression and a secondary increase in intra-abdominal pressure as well as with the action of shearing forces during deceleration. Conclusions: Traumatic MD injuries are differentiated and very rare. They can coexist with other serious injuries to the abdominal organs.

Potential role of physical labor and cultural views of menstruation in high incidence of pelvic organ prolapse in Nepalese women: a comparative study across the menstrual cycle.

Pelvic organ prolapse (POP) is a significant health concern for young Nepali women, with potential risk factors including pelvic floor trauma from vaginal delivery and heavy lifting. The prevalence of symptomatic POP (SPOP) among nulliparous women in Nepal is 6%, while the general population of Nepali women aged 15-49 years reports a prevalence of 7%. Surprisingly, the average age of SPOP onset in Nepal is 27 years, challenging the assumption that postmenopausal age and vaginal delivery are the sole risk factors. This study aims to investigate the influence of increased intra-abdominal pressure (IAP) during lifting tasks on pelvic organ descent in Nepali women across different menstrual cycle stages. The study included 22 asymptomatic Nepali women aged 18-30 years who regularly engage in heavy lifting. Intra-abdominal pressure was measured intra-vaginally during typical and simulated lifting tasks, which encompassed various scenarios such as ballistic lifting, ramped lifting, and pre-contraction of pelvic floor muscles, as well as coughing, Valsalva maneuver, and pelvic floor contractions. Pelvic floor displacement was recorded using transperineal ultrasound during menstruation, ovulation, and the mid-luteal phase. Results indicated that pelvic floor displacement was greater during menstruation than ovulation when performing a simulated ballistic lifting task (6.0 ± 1.6 mm vs. 5.1 ± 1.5 mm, p = 0.03, d = 0.6). However, there was no significant difference in pelvic floor displacement during lifting when the pelvic muscles were pre-contracted. These findings suggest that lifting heavy loads during menstruation may increase the risk of stretching and injuring pelvic floor supportive tissues, potentially contributing to SPOP in young Nepali women. Pre-contracting pelvic floor muscles during lifting tasks may offer a protective effect. Understanding these factors could aid in developing targeted preventive measures and raising awareness about the impact of heavy lifting on pelvic floor health among Nepali women.

Assessment of Involuntary PFM Contractions in Comparison with Existing Literature and IUGA/ICS Terminology Reports

Introduction and HypothesisInvoluntary pelvic floor muscle (PFM) contractions are thought to occur during an increase in intra-abdominal pressure (IAP). Although no studies have assessed their presence in women with normal pelvic floor (PF) function, existing literature links the absence of involuntary PFM contractions to various PF dysfunctions. This study rectifies this lacuna by evaluating involuntary PFM contractions during IAP in healthy nulliparous women with no PF dysfunction, using visual observation and vaginal palpation. Results were compared with the literature and the IUGA/ICS Terminology Reports.MethodsNulliparous (n=149) women performed three sets of three maximal coughs. Visual observation and vaginal palpation were conducted in the standing and supine positions. The women were not instructed to contract their PFMs. Occurrence rates were calculated for each assessment method and position; differences between positions were analyzed using the Chi-squared test.ResultsRates of occurrence of involuntary PFM contraction were low across both assessments and positions (5–17%). Significant differences were found between standing (5%) and supine (15%) positions for visual observation, but not vaginal palpation (15%, 17% respectively). Occurrence rates also differed compared with the literature and terminology reports.ConclusionsContrary to clinical expectations, rates of occurrence of involuntary PFM contraction among our cohort of nulliparous women were extremely low. Digital palpation results showed high agreement with the terminology reports, but only partial agreement was observed for the visual observation results. Our study underscores the need for more research aimed at defining normal involuntary PF functions, a review of our understanding of involuntary PFM contractions, and better standardized guidelines for involuntary PFM assessment methods.

Intra-abdominal pressure and residual renal function decline in peritoneal dialysis: a threshold-based investigation

Background The potential impact of elevated intra-abdominal pressure (IAP) on residual renal function (RRF) has not been determined. The objective of this study was to investigate the relationship between IAP and the rate of RRF decline in newly initiated peritoneal dialysis (PD) patients, and to identify the optimal IAP threshold value for delaying the deterioration of RRF. Methods A cohort of 62 newly initiated PD patients who completed both 6- and 12-month follow-up evaluations was obtained using the Durand method. A logistic regression model was used to identify variables associated with a rapid decline in RRF. Receiver operating characteristic (ROC) curves were generated to determine the optimal threshold value. Another retrospective cohort analysis was performed to validate the identified critical value. Results For each 1 cmH2O increase in IAP, the risk of a rapid decline in the RRF increased by a factor of 1.679. Subsequent analysis revealed that patients in the high IAP group had more significant decreases in residual renal estimated glomerular filtration rate (eGFR) (Z = −3.694, p < 0.001) and urine volume (Z = −3.121, p < 0.001) than did those in the non-high IAP group. Furthermore, an IAP ≥15.65 cmH2O was a robust discriminator for the prediction of the rate of RRF decline. Conclusion Patients in the high IAP group experienced a more rapid decline in RRF. Additionally, an optimal critical pressure of 15.65 cmH2O was identified for predicting the rate of RRF decline. IAP, as one of the factors contributing to the rapid decline in RRF in the first year of PD, should be given due attention.

Clinical Observations in Patients With Open Abdomens Managed With Negative Pressure Therapy Using a Perforated Foam Dressing: A Limited Case Series With Brief Literature Review

Introduction. Emergency laparotomy has become an increasingly more frequent and expensive general surgery procedure in terms of cost and resource utilization. Primary fascial closure at the index procedure may not be feasible in many patients, requiring use of the open abdomen (OA) technique. Patients with OA are most often managed with temporary abdomen closure (TAC). Open abdomen negative pressure therapy (OA-NPT) has been shown to be an effective TAC technique, which facilitates re-exploration, protects visceral organs, mitigates fascial retraction, prevents loss of abdominal domain, and provides effective volumetric abdominal fluid management. Objective. This study assessed the clinical use and outcomes of a next-generation perforated polyurethane foam dressing that has been developed for use with OA-NPT. Materials and Methods. The authors evaluated a next-generation OA-NPT foam dressing to provide TAC in 4 patients who required OA management. Two surgeons at different facilities exercised their independent surgical discretion in selecting the patients who would receive the next generation OA-NPT foam dressing. Surgical interventions to resolve the underlying pathology were completed using the OA technique. Postoperatively, all patients had intermittent urinary bladder pressures recorded as an indirect method for approximating intra-abdominal pressure (IAP) and to monitor clinical evidence of intra-abdominal hypertension (IAH) or abdominal compartment syndrome. Results. In these patients, primary fascial closure was achieved and no appreciable increase in IAP was noted. No gastrointestinal complications related to the next generation perforated OA-NPT foam dressing were noted. Conclusions. Based on the authors' clinical assessment of the 4 patients who required OA management, the new, perforated OA-NPT foam dressing was effective in providing increased medial tension and contraction without an appreciable increase in IAP.

Stress Urinary Incontinence in Young Female Athletes- From Prevalence to Treatment- A Review

Urinary incontinence is a prevalent issue among females aged 15-65, with prevalence rates ranging from 10% to 55%. Stress Urinary Incontinence (SUI) is the most common form in young athletes, with rates ranging from 0% (golf) to 80% (trampolinists). Activities like jumping, landing, and running can cause leakage due to an increase in intraabdominal pressure. This study aimed to identify management strategies and the prevalence of SUI in teenage female athletes. A literature search was conducted on studies conducted between 1990 and the present, excluding abstracted and non-open access studies. The research found that the chance of urinary stress incontinence in young and nulliparous female athletes in sports ranges from 0% (golf) to 80% (trampolinists). These activities, including gymnastics, long jumps, track and field, and ball activities, significantly impact their standard of existence, psychological situation, and athletic performance. Effective conservative treatment options for SUI include behavioral and lifestyle modifications, pelvic floor exercises, and core strengthening exercises. Female athletes require significantly stronger pelvic floor muscles than inactive females, and contraction of these muscles should occur as the inner core muscles are engaged. Future studies, instruction, and focused therapies are needed for female athletes with SUI.

Comparative Analysis of Haemodynamic and Capnographic Changes in Laparoscopic Cholecystectomy and Open Cholecystectomy: A Randomised Clinical Study

Introduction: Laparoscopic cholecystectomy is now preferred over the open procedure due to advantages such as reduced blood loss and shorter hospital stays. However, concerns have been raised regarding the potential for increased Intra-abdominal Pressure (IAP) during laparoscopic procedures, which may impact haemodynamic stability and respiratory parameters. However, there is a lack of comprehensive analysis directly comparing both surgical approaches from both haemodynamic and capnographic perspectives. Aim: To compare the haemodynamic and capnographic changes between laparoscopic and open cholecystectomy. Materials and Methods: This randomised clinical study was conducted at Department of Anaesthesiology, Assam Medical College and Hospital, Dibrugarh, Assam, India from May 2021 to June 2022. The study included 300 patients scheduled for cholecystectomy, divided into two groups: Laparoscopic Cholecystectomy (LC) Group I (n=150) and Open Cholecystectomy (OC) Group II (n=150). Haemodynamic parameters, including Pulse Rate (PR), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), Mean Arterial Pressure (MAP), and Oxygen Saturation (SpO2 ), were recorded. Capnographic parameters, such as End-Tidal Carbon Dioxide (EtCO2 ) levels, were also measured at regular intervals. Data analysis was performed using the student’s t-test and Chi-square test with Statistical Package for Social Sciences (SPSS) version 21.0 software and Microsoft excel. Results: There were no significant differences in age, body weight, and sex distribution between Group I and Group II. However, significant differences were observed in PR and SBP at 15 minutes (PR: 101.46 and 95.86; SBP: 148.57 and 140.97), 30 minutes (PR: 104.52 and 99.82; SBP: 141.28 and 136.07), and 45 minutes (PR: 102.52 and 97.70; SBP: 140.59 and 133.95) (p-value &lt;0.01). Highly significant differences were observed in MAP and EtCO2 postinsufflation at 15 minutes (MAP: 118.38 and 108.61; EtCO2: 36.48 and 33.89), 30 minutes (MAP: 111.11 and 106.01; EtCO2: 41.02 and 36.15), 45 minutes (MAP: 110.73 and 103.48; EtCO2: 42.65 and 38.36), and 60 minutes (MAP: 106.08 and 101.45; EtCO2: 41.10 and 38.21) (p-value &lt;0.01). DBP showed high significance at 15 minutes (103.21 and 93.23), 30 minutes (96.74 and 92.57), and 60 minutes (93.14 and 86.92) (p-value &lt;0.01), and significant (p-value=0.01) at 45 minutes (95.53 and 87.59). Oxygen saturation showed significance (p-value &lt;0.05) at 15 minutes (99.93 and 100). Conclusion: The present study demonstrated a significant increase in both haemodynamic and capnographic parameters, even in American Society of Anaesthesiologists (ASA) Grade-I and Grade-II patients undergoing laparoscopic cholecystectomy compared to the open surgical technique. These findings emphasise the need for careful monitoring during laparoscopic procedures.
