In this trial, 100 patients undergoing robotic prostatectomies will be randomised to have either the AIRSEAL® Insufflation System (AIS) or the Stryker PneumoClear Insufflator devices used to maintain pneumoperitoneum during surgery. Data relating to intra-operative and post-operative pain will be collected. This data will be used to identify any differences in outcomes between the two arms of the trial. The main aim of this feasibility study will be to inform the feasibility and design of a subsequent definitive full-scale trial. The feasibility trial will collect data about recruitment, study conduct, and assessment methods. The objectives of the feasibility are to * Assess recruitment rates * Evaluate whether the study can run in line with the study protocol * Identify the feasibility of collecting clinical data * Evaluate treatment-based adverse events, serious adverse events, anticipated adverse device effects, unanticipated adverse device effects and all device deficiencies and use errors, regardless of relationship to an adverse event * Estimate the likely magnitude of the effect of the intervention. To allow for estimation of the sample size for the full trial The subsequent large scale, multi-center trial following this feasibility trial will focus on severity of pain during and immediately after surgery in the recovery room and then by 6-hour increments, measured by a 0 - 10 Numeric Rating Scale (NRS) and a PMD-200 nociception non-invasive monitor as the primary outcome Secondary outcomes include: Pre-Operative 1. Pre-op vitals including height and weight 2. Pre-op labs Intra-operative 1. Insufflation Pressure 2. Estimated blood loss 3. Blood transfusion (intra-operative) 4. Procedure time (initial incision to closure) 5. Surgeon-determined need to increase IAP beyond "study pressure" 6. Administration of transversus abdominis plane block 7. Urine output 8. Anesthetic/pain medication administration 9. MedaSense PMD-200 monitor for pain documentation 10. Intraoperative Peak Airway Pressure every 15 minutes 11. Intraoperative End Tidal Carbon Dioxide (ETCO2) every 15 minutes Post-Operative During hospital discharge, all subjects will be evaluated for incidence and severity of pain using a 0-10 numeric rating scale (NRS) and records of medication use and a PMD-200 monitor. These data will be captured in the Case Report Forms. Recovery room: 1. Time in recovery room 2. Post-op pain incidence and severity (abdominal) NRS 3. Pain medications 4. Post- op labs (CBC, Chem-7) per standard of care 5. Vital signs 24 hr Discharge: 1. Post-op pain incidence and severity (abdominal) NRS 2. Presence or absence of postoperative nausea or vomiting 3. Pain medications 4. Length of hospital stay 5. Pain Interference and Pain Intensity short form surveys 6. Any complications that were observed. Post-operative complications through 30 days, reported using Clavien-Dindo Classification, including 30-day mortality 7. Return to operating room within 24 hour 8. Readmission to hospital within 30 days Classification, including 30-day mortality All Adverse Events (intra-operative and post-operative through 30 days): 1. Adverse Events 2. Serious Adverse Events 3. Anticipated Adverse Device Effects 4. Unanticipated Adverse Device Effects 5 All device deficiencies and use errors, regardless of relationship to an adverse event Patients under the care of the urology department at the Lister Hospital, Stevenage will be listed in clinic for a robotic prostatectomy. If patients meet the eligibility criteria for the trial, they will be approached and informed of the RALP clinical trial during their clinic consultation, by a member of the clinical team (likely a urological consultant). Patients will be provided with a patient information sheet informing them of the aims and methodology of the trial. Members of the research department will be able to answer any outstanding questions patients might have. Written informed consent will be obtained from eligible patients (n=40) willing to participate in the trial. If patients consent, their GP will subsequently be written to and informed of their involvement in the trial. Pre-Operative data collection: Within 30 days of a subject's scheduled procedure, members of the research department at Lister hospital will obtain a medical history and record the subject's demographic (age, race, sex and date of birth) and baseline information (height, weight, and systolic/diastolic blood pressure). Within 30 days prior to the planned procedure date, obtain serum blood tests per standard of care. These will typically include: • FBC • Renal function test • CRP This data, along with all subsequent trial related data will be anonymised and subsequently inputted into a database created by the Centre for Health Services and Clinical Research at the University of Hertfordshire. Preoperative Randomization: Randomization will be done electronically via a database which is facilitated by the University of Hertfordshire. Patients will be randomized 1:1 to either AIS (at 8 mmHg) or Stryker PneumoClear Insufflator Arm 1: AIRSEAL® Insufflation System (AIS) - 8 mmHg Arm 2: Stryker PneumoClear Insufflator - 8 mmHg. Methods and Procedure: Patients will undergo their robotic assisted prostatectomy with the use of either the AIRSEAL® Insufflation System (AIS) or Stryker PneumoClear Insufflator depending on which arm of the trial they have been randomized to. Patients will be blinded to the intervention (AIRSEAL® Insufflation System (AIS) or Stryker PneumoClear Insufflator). Both systems are commonly used devices across many NHS trusts and there is currently no evidence comparing patient outcomes between use of the two devices. This study will be conducted at one site by one surgeon performing 40 total procedures. Study subjects will be prepared for surgery per standard institutional policy and practice. Standard operative procedures will be followed. Case Report Forms will be also be used to collect data relating to pre-operative, intra-operative and post-operative outcomes. This data will relate to outcomes such as intra-operative pain, post operative pain scores, medication use, duration of hospital stay, presence of nausea or vomiting etc... The final patient follow up will be in a clinic appointment 30 days following their operation. Ongoing post-operative outcomes will be assessed (pain scores, medication use, adverse events etc...). Data will be inputted on the database which is subsequently processed and statistically analysed and reviewed. Differences in outcomes between the two arms of the trial may be identified. Once the aforementioned data has been processed and reviewed, results may be published and also distributed to those trial participants who wished to receive ongoing information and results from the trial. The outcomes of this research will be used to inform future research such as a full scale trial with a larger number of patients and larger volume of data
