Postoperative epidural analgesia following radical retropubic prostatectomy: outcome assessment

Open radical retropubic prostatectomy 2007: the true minimally invasive surgery for localized prostate cancer?

The introduction of robotic laparoscopic assisted prostatectomy at our institution and nationwide has been a great advancement and has caused us to focus and fine-tune our goal for improvements in prostate cancer outcomes whether the patient elects for robotic laparoscopic assisted prostatectomy or open minimally invasive radical retropubic prostatectomy. While these authors favor the open technique performed by highly skilled urologic surgical oncologists, the lessons we have learned to date suggest that it is the skill of the surgeon that determines outcome, regardless of whether or not the operation is performed by an open or robotic laparoscopic technique. The concepts we have articulated here are related to resection and avoidance of positive margins, limited intraoperative blood loss and pain control, which allow equivalence in these outcome areas, regardless of technique.

Epidural anesthesia and cancer recurrence rates after radical prostatectomy

PURPOSE

To determine the effect of adjunctive epidural local anesthetic and opioid infusion on disease recurrence following radical prostatectomy for adenocarcinoma under general anesthesia.

METHODS

This article describes a secondary analysis of subjects undergoing radical prostatectomy who had participated previously in a randomized controlled trial evaluating pain control, blood loss, and the need for perioperative allogeneic blood transfusion. The patients were randomly allocated to receive either general anesthesia alone (control group; n = 50) or combined general/epidural anesthesia (study group; n = 49). A long-term follow-up chart review was undertaken to determine clinically evident or biochemical (Prostate Specific Antigen > 0.2 ng x mL(-1)) recurrence of prostate cancer. Comparison by group was undertaken using survival analysis.

RESULTS

Median disease-free survival for the study as a whole was 1644 days, and the longest recorded survival was 3403 days. Biochemical recurrence of prostate cancer was observed in 11/49 study subjects and 17/50 control subjects. There was one death from prostate cancer in each group and a total of five deaths in the study group and six deaths in the control group. The hazard ratio for recurrence in the study group compared with the control group was 1.33 (95% confidence intervals 0.64-2.77; P = 0.44 by log-rank test).

CONCLUSION

No difference was observed between the epidural and control groups in disease-free survival at a median follow-up time of 4.5 years. There is a need for large randomized controlled trials to determine the ability of epidural analgesia to alter disease recurrence rates following radical prostatectomy.

Oral oxycodone hydrochloride versus epidural anaesthesia for pain control after radical retropubic prostatectomy

OBJECTIVE

To evaluate whether combined oral intake of paracetamol (4 x 1 g) + oxycodone hydrochloride (2x10 mg) is adequate and equivalent to epidural anaesthesia (EDA) with respect to postoperative pain control and postoperative mobilization after radical retropubic prostatectomy (RRP).

MATERIAL AND METHODS

Forty consecutive patients scheduled for RRP were randomized to either: EDA with ropivacaine + paracetamol (4 x 1 g tablet) + injected or oral morphine on demand (EDA group); or infiltration of 25-40 ml of 0.25% bupivacaine into the wound + oxycodone hydrochloride (2 x 10 mg tablet) + paracetamol (4x1 g tablet) + injected or oral morphine on demand (OXY group). The groups were compared with respect to pain control determined by means of a visual analogue scale (VAS), time to free mobilization, hospital stay, complications, operation time and bleeding.

RESULTS

Both analgesic regimens provided satisfactory analgesia, i.e. VAS scores remained significantly below 4 (p<0.0001). The EDA group experienced slightly less pain than the OXY group on the operation day but this was not significant: median VAS scores of 0.7 and 1.8, respectively (p=0.27). Median VAS scores during hospital stay were 1.7 in both treatment groups. VAS scores ranged from 0.1 to 3.3 and from 0.2 to 3.5 in the EDA and OXY groups, respectively. There was no significant difference in postoperative mobilization between the groups (p=0.06). The median duration of hospital stay was 3 nights in both groups.

CONCLUSION

Postoperative pain control after RRP with oral oxycodone hydrochloride, paracetamol and extra morphine on demand is preferable to EDA when pain control as well as mobilization and costs are taken into account.

[Peridural application of ropivacaine and clonidine for pain therapy after prostatectomy]

OBJECTIVE

The aim of this study was to find out if ropivacaine with clonidine can be successfully used after radical retropubic prostatectomy.

MATERIAL AND METHODS

A total of 86 patients were randomized into two groups each consisting of 43 patients. Patients in group 1 received epidural bupivacaine/morphine/clonidine and those in group 2 ropivacaine and clonidine. If necessary analgesic, antiemetic or antihistamine drugs were administered. Pain on a visual analogue scale (VAS), motoric and sensoric disturbances, sedation, itching, nausea and vomiting, hypotension, need of antihistamines, naloxon, antiemetics, ephedrine, and analgesics were also documented.

RESULTS

Differences in sedation, itching, nausea and vomiting, motoric and sensoric disturbances, need of antihistamines, antiemetics, and ketoprofen were significant, the other parameters did not show any significant differences.

CONCLUSIONS

We recommend the use of ropivacaine with clonidine in the postoperative pain management after radical retropubic prostatectomy.

Central venous pressure monitoring during living right donor hepatectomy

Low central venous pressure (CVP) has been advocated during liver resection to reduce blood loss and transfusion requirements. As a consequence, CVP catheter placement has been considered essential for hepatic surgery, including living donor hepatectomies. We retrospectively analyzed whether intraoperative management without CVP monitoring influenced fluid administration, blood loss, and patient outcome. Medical charts and hospital data system of 50 adult to adult living liver donors were retrospectively reviewed. Data collection included patient demographics, intraoperative variables such as fluid management, blood loss, urine output, and operating room time. Postoperative variables were collected during the postanesthesia care unit stay and for the first 24 hours after surgery. Patients were then grouped on the basis of the presence or absence of a CVP catheter. Data were reanalyzed and groups compared. Patient groups did not differ in terms of demographics at baseline. When divided into groups with CVP and without CVP, the presence of CVP did not result in decreased intraoperative fluid administration. All patients were hemodynamically stable, and renal function was not different between groups throughout hospitalization. Length of postanesthesia care unit and hospital stay was the same. There was no difference in the frequency of complications during the hospital stay and at 3 months' follow-up. CVP monitoring did not appear to reduce blood loss when compared with patients without CVP monitoring. In centers with extensive experience, CVP monitoring may not be necessary in this highly selective patient population.

Induced hypotension with epidural/general anesthesia reduces transfusion in radical prostate surgery

PURPOSE

Radical prostatectomy is associated with substantial blood loss frequently requiring allogeneic blood transfusion. We investigated the efficacy of deliberate hypotension using combined epidural/general anesthesia in reducing allogeneic transfusion requirements in patients undergoing radical prostatectomy.

METHODS

In a prospective, randomized, single-blind trial, 102 patients undergoing radical prostatectomy were allocated to either an epidural group (n = 51) or a control group (n = 51). In the epidural group, deliberate hypotension was achieved with a target mean arterial pressure of 55-60 mmHg. The trigger for allogeneic blood transfusion in both groups was a hematocrit value < 0.25.

RESULTS

Operative blood loss in the epidural group was significantly less than that in the control group (955 +/- 517 mL vs 1477 +/- 823 mL respectively, P < 0.001). The percentage of patients who reached the threshold trigger for allogenic transfusion was significantly less in the epidural group (8% vs 26%, respectively, P = 0.019) and the number of patients who were actually transfused during hospitalization was also significantly less (P = 0.028). There were no serious adverse events in either group during the study.

CONCLUSION

Controlled hypotension using a combined epidural/ general anesthetic technique is associated with significantly less blood loss, and a reduction in the use of allogeneic blood in patients undergoing radical prostatectomy compared to general anesthesia alone.

Perioperative complications of radical retropubic prostatectomy

The opinions and assertions contained herein are the private views of the authors and are not to be construed as reflective of the views of the US Army or the Department of Defense. Radical retropubic prostatectomy has long been considered one of the most difficult procedures in the urologist's armamentarium. Therefore, we performed a thorough review of recent literature regarding intraoperative and postoperative complications. The intent of this effort is to review established data regarding the most frequently seen complications and to highlight recent developments regarding the prevention or treatment of such complications.

[Anaesthesia and prostate surgery]

OBJECTIVES

To review the current data about anaesthetic management in prostate surgery with special regards on analysis and prevention of specific risks, appropriate anaesthetic procedure keeping with surgery and patient, recognition and treatment of adverse events.

DATA SOURCES AND EXTRACTION

The Pubmed database was searched for articles (1990-2004) combined with references analysis of major articles on the field.

DATA SYNTHESIS

It is strongly recommended to settle germfree urine in the preoperative period. The thromboembolic risk of radical retropubic prostatectomy for cancer parallels lower abdomen oncologic surgery and is prolonged. Preoperative evaluation of cardiovascular, respiratory, neurological and metabolic comorbidity is a source of prognostic information and an essential tool in the management of elderly patients with prostate disease. Extreme patient positioning applied in prostate surgery induces haemodynamic and respiratory changes and are associated with severe muscular and nervous injuries. The laparoscopic access for radical prostatectomy is a growing alternative to the open surgical procedure. Acute normovolaemic haemodilution is a consistent and cost-effective blood conservation strategy in reducing allogenic blood transfusion for radical retropubic prostatectomy. Whether open transvesical or transurethral prostatectomy for treatment of benign hypertrophy depends on the size of the gland: transurethral resection is safe up to 80 g. Intrathecal anaesthesia with a T9 cephalad spread of sensory block, produces adequate conditions for transurethral prostatectomy and allows a rapid diagnosis of irrigating fluid absorption syndrome. In spite of recommended preoperative antibiotic prophylaxis, bacteriemias are frequent during transurethral prostate resection.

General Anesthesia versus Epidural and General Anesthesia in Radical Cystectomy

INTRODUCTION

The aim of this study is to compare two different anesthetic techniques in radical cystectomy with regard to blood loss, transfusional requirements, intraoperative complications and the quality of analgesia.

MATERIALS AND METHODS

50 patients scheduled for radical cystectomy were randomized to two groups: group GA - general anesthesia, n = 25 and group CEGA - combined epidural and general anesthesia. The patients were monitored and hemodynamic changes, intraoperative bleeding, transfusional requirements, quality of analgesia and postoperative complications were evaluated.

RESULTS

There were no significant differences between the demographic characteristics of the two groups. Intraoperative bleeding which was 874.8 +/- 190.7 ml in the CEGA group and 1,248.3 +/- 343.4 ml in the GA group was statistically different (p < 0.05). Significantly more intraoperative blood transfusions in terms of units were required in the GA group. Analgesia was better in the CEGA group, with VAS values at 0, 1, 2, 4, 6, 12 and 24 h significantly (p < 0.05) lower than those observed in the GA group. No significant differences in intraoperative hemodynamic parameters or postoperative complications were noted between the two groups.

CONCLUSIONS

Statistically significant differences in intraoperative bleeding were observed between the two groups: CEGA provides lower intraoperative bleeding and a better postoperative analgesia. Major operations such as radical cystectomy, which also is associated with considerable blood loss, a combination of general and epidural anesthesia may allow for less blood loss, with a better postoperative analgesia and without any increase in complications.
