Seguridad y efectividad del tratamiento del dolor agudo postoperatorio: seguimiento de 3.670 pacientes

To improve the safety and effectiveness of acute postoperative pain treatment in patients under the care of our acute pain clinic, we set 3 objectives: to establish a computerized registry updated daily for all patients treated in the unit, to define categories of quality indicators for assessing the results of acute postoperative pain treatment, and to compare our results with those reported in the literature. Prospective study of all patients treated by our pain clinic from May 2004 through June 2007. We analyzed 19 previously defined indicators in 4 categories: case characteristics, effectiveness, safety, and patient satisfaction. We then compared the results to those in the literature. A total of 3670 patients were included. Results for the most important indicators were as follows: mean follow-up time, 3.1 days (range 1-12 days); effectiveness, 92%; severe pain (>7 on a numerical scale) at rest, 1%; moderate pain (4-6 on the scale) on movement, 31%; accidental catheter removal, 6%; and medication error, 0.4%. Daily follow-up and recording of data for patients treated by the acute pain unit facilitates the evaluation of our clinical practice and contributes with improving safety and effectiveness. Comparison with reports in the literature reveals the great heterogeneity of quality assurance indicators that have been defined.

Indwelling interscalene catheter use in an outpatient setting for shoulder surgery: Technique, efficacy, and complications

Indwelling interscalene catheters are utilized for inpatient postoperative pain control after shoulder surgery. Improved medical equipment and advanced techniques may allow safe and efficacious outpatient use. One hundred and forty-four consecutive indwelling interscalene catheter placements were reviewed to determine adverse events, complications, and efficacy. Real-time ultrasound-guided catheter placement technique is described. Post-anesthesia care unit (PACU) narcotic consumption and last recorded pain score were reviewed to gauge efficacy. The catheter placement technique was 98% successful. There were 14 (9.7%) minor adverse events including inadequate analgesia (8), accidental catheter removal (4) of disconnection (1), and shortness of breath (1). The single complication (0.7%) was a small apical pneumothorax. The average PACU narcotic consumption in intravenous morphine equivalents was 1.7 mg. The average last recorded PACU pain score on a scale of 1 to 10 was 0.6. Catheter placement under real-time ultrasound guidance is accurate. Outpatient use of indwelling interscalene catheters is safe and efficacious.

Internal jugular and subclavian catheterisation: indications, problems and prospects in a Nigerian dialysis centre

To highlight the indications, problems and prospects of bedside non-surgically inserted jugular and subclavian dual lumen catheters. Renal failure patients being managed in our centre with indications for central catheterisation were consecutively recruited at presentation. They had bedside non-surgical jugular and subclavian insertion of central catheters using modified Seldinger wire technique and the performance of the catheters monitored. Sixteen patients aged between 23 and 65 years had 32 central catheterizations during the 12-month period. The indications included its use as haemodialysis access in all catheterisations, additional indications were CVP monitoring in 5, and parenteral hyperalimentation in 1. Three catheterisations were in right subclavian vein, 4 in left internal jugular vein and 25 in right internal jugular vein. The duration of use ranged between 3 days and 11 weeks and blood flow rate used ranged between 250 and 350 mls/min. Nine (28.1%) catheterisations were complicated with exit site and systemic infection. Catheter blockage and accidental catheter removal were recorded in 3 patients each. Carotid artery puncture was recorded in 2 patients but haemostasis was maintained with direct digital compression. We conclude that percutaneous bedside internal jugular and subclavian (venous) catheterisation using dual lumen catheter is safe and devoid of major complications.

Accidental catheter removal in the intensive care unit: a prospective observational study

Accidental catheter removal (ACR) is associated with complications caused by the removal itself and by catheter reinsertion. Hence determining the incidence is important to implement preventive measures. The objective of the present study was to analyse the incidence of ACR for all types of catheters in the ICU.

Salvage Insertion of Tunneled Central Venous Catheters in the Internal Jugular Vein after Accidental Catheter Removal

Tunneled catheters are widely used for intermediate to long-term hemodialysis (HD) access, but are prone to several complications that can require catheter replacement. Replacing malfunctioning catheters with a new line, placed in a different access site, can lead to problems with multiple vein occlusions. This has led many nephrologists to continue using the same vein as long as possible by guidewire catheter exchanges, to preserve other veins for future use. We describe a guidewire exchange technique for the Ash-Split catheter in the internal jugular vein. In three patients, the exchange was performed because of partial catheter removal, as evidenced by the outward dislocation of the Dacron cuff. In these patients, the guidewire was inserted through the catheter. In two additional patients, the catheter had been completely removed by accident: the replacement of the dislodged tunneled venous catheters was attempted 5 hr and 1 day after accidental removal. In these patients, the guidewire was inserted through the previous tunnel. After guidewire placement, a skin incision was made in the supraclavicular region. The metal guidewire was easily located inside the fibrous structure that had previously surrounded the catheter. The guidewire was then extracted from the subcutaneous tunnel and used to insert a new catheter safely and easily after creating a new tunnel. Patients were routinely given antibiotic prophylaxis (1 g of cefazolin) immediately before the procedure. A strict aseptic technique was used, including several sterile glove changes. No infections developed following this procedure, which has the potential for bacterial contamination. All procedures were successful. Only in one patient did we have to convert to a different catheter: it was not possible to replace the old Ash-Split catheter with the same dual-lumen catheter because of difficulties in inserting the peel away introducer-catheter complex. In this patient, rather than forcing it with larger dilators or trying to disrupt the fibrin sheath with balloon dilatation, a single lumen Tesio catheter was successfully placed. In both patients who completely lost the previous catheter, the guidewire was readily reinserted through the subcutaneous tunnel into the vein. Catheter function was excellent in all patients, with a test blood flow rate on the 1st catheter use >350 ml/min. We described a new method for catheter exchange, which allows the easy insertion of a new catheter and the creation of a new and safer subcutaneous tunnel. In addition, we demonstrated that in cases of complete catheter removal, it is possible to reinsert a catheter in the same vein through a guidewire, even when reinsertion was attempted up to 1 day later.

Accidental catheter removal in critically ill patients: a prospective and observational study

IntroductionThe importance of accidental catheter removal (ACR) lies in the complications caused by the removal itself and by catheter reinsertion. To the best of our knowledge, no studies have analyzed accidental removal of various types of catheters in the intensive care unit (ICU). The objective of the present study was to analyze the incidence of ACR for all types of catheters in the ICU.MethodsThis was a prospective and observational study, conducted in a 24-bed medical/surgical ICU in a university hospital. We included all consecutive patients admitted to the ICU over 18 months (1 May 2000 to 31 October 2001). The incidences of ACR for all types of catheters (both per 100 catheters and per 100 catheter-days) were determined.ResultsA total of 988 patients were included. There were no significant differences in ACR incidence between the four central venous access sites (peripheral, jugular, subclavian and femoral) or between the four arterial access sites (radial, femoral, pedal and humeral). However, the incidence of ACR was higher for arterial than for central venous catheters (1.12/100 catheter-days versus 2.02/100 catheter-days; P < 0.001). The incidences of ACR/100 nonvascular catheter-days were as follows: endotracheal tube 0.79; nasogastric tube 4.48; urinary catheter 0.32; thoracic drain 0.56; abdominal drain 0.67; and intraventricular brain drain 0.66.ConclusionWe found ACR incidences for central venous catheter, arterial catheter, endotracheal tube, nasogastric tube and urinary catheter that are similar to those reported in previous studies. We could not find studies that analyzed the ACR for thoracic, abdominal, intraventricular brain and cardiac surgical drains, but we believe that our rates are acceptable. To minimize ACR, it is necessary to monitor its incidence carefully and to implement preventive measures. In our view, according to establish quality standards, findings should be reported as ACR incidence per 100 catheters and per 100 catheter-days, for all types of catheters.

Patterns of presentation and mortality in tetanus: a 10-year retrospective review

To highlight the indications, problems and prospects of bedside non-surgically inserted jugular and subclavian dual luman catheters. Renal failure patients being managed in our centre with indications for central catheterisation were consecutively recruited at presentation. They had bedside non-surgical jugular and subclavian insertion using modified seldinger wire technique and the performance of the Gatheters monitored. Sixteen patients aged between 23 and 65 years had 32 central catheterisations during the 12-month period. The indications included its use as haemodialysis access in all patients, additional indications were CVP monitoring in 5, and parenteral hyperalimentation in 1. Three catheterisations were in right subclavian vein, 4 in let internal jugular vein and 25 in right internal jugular vein. The duration of use ranged between 3 days and 11 weeks and blood flow rate used ranged between 50 and 350ml/min. Nine (28.1%) catheterisations were complicated with exit site and systemic infection. Catheter blockage and accidental catheter removal were recorded in 3 patients each. Carotid artery puncture was recorded in 2 patients but haemostasis was maintained with direct digital compression. We conclude that percutaneous bedside internal jugular and subclavian (venous) catheterisation using dual lumen catheter is safe and devoid of major complications. Tetanus, an ubiquitous disease still ravages our population despite the fact that it is totally preventable. The mortality had remained high with its attendant socio-economic implications as it affects mainly farmers in their prime of life. We conducted this retrospective review to be able to determine pattern of presentation, case fatality rate and factors influencing mortality with a view to mapping out control strategies. The case records of all managed patients aged 16 and above over a ten-year period (1992-2001) were retrieved and socio-demographic and clinical data as well as results of laboratory investigations were collated. Analysis was done using SPSS package. Chi-square analysis and student t-test were used for comparison of means as appropriate. P-values of <0. 05 was taken as significant. There were a total of 114 patients managed during the period, which comprised of 85 males and 29 females. The means age (+/- SD) was 35.96 (+/-17.76). Sixty six (57.89%) patients are either jobless or farmers. Majority of the patients had injuries in the lower limb 59.65% when compared with 20.18% that had theirs in the upper limb. 107 (93.86%) of the patients presented with trismus while only 82 (71.93%) had opsthotonus. Only 51 (44.73%) patients survived while 61 (53.5%) died. The mean age (+/- SD) of the survivors was 32.35 (+ 14.45) years while that of those that died was 39.4 (+/- 19.89) years (P = 0.036). Other factors that significantly influenced survival included severity of spasms (P = 0/003), tachycardia (P = 0.044), and degree of sedation (P <0.0001). No association was found between survival and incubation period, period of onset, site of injury and associated medical conditions. Tetanus is still associated with high mortality rate. Factors such as severity of spasma, age, sedation and tachycardia were found to significantly influence mortality. It is recommended that prophylactic life immunisation against tetanus be given to all Nigerians.

Post-splenectomy thrombocytopenia: implications for regional analgesia.

Hospital computerised records were reviewed to identify patients who had undergone splenectomy, then chart their platelet count before and for the 5 days after the operation. A pre-operative platelet count less than 100 x 10(9).l-1 occurred in 66% of leukaemia (n = 35), 56% of lymphoma (n = 41) and 5% of solid tumour (n = 39) patients. Platelet supplementation prior to epidural catheter insertion may reduce the risks of spinal bleeding. However, accidental catheter removal during a postoperative period of thrombocytopenia may lead to formation of an epidural haematoma. The lowest postoperative platelet count was less than 100 x 10(9).l-1 in 66% of leukaemia, 27% of lymphoma and 13% of solid tumour patients. Platelet counts varied considerably, so predicting an individual patient's postoperative nadir from the pre-operative count would be impossible. Consequently, placement of an epidural catheter in many of these patients could expose them to an increased risk of spinal bleeding if the catheter is removed accidentally.

Bladder dysfunction following schauta hysterectomy

Thirty-one consecutive patients were studied by serial cystometrograms following radical vaginal operation. Contrary to the prevailing thought, 95 per cent of patients demonstrated a hypertonic rather than hypotonic type of bladder dysfunction. The hypertonic alteration, although improved, tended to persist even after clinical return of bladder function. Bladder atony, which occurred in only 2 patients, resulted from overdistention following accidental catheter removal. The average duration of catheter drainage was 50.2 days. In 16 patients (51.2 per cent), the indwelling catheter was removed in less than 6 weeks; the longest duration was 169 days. Recommendations are made for the management of bladder dysfunction following radical pelvic operation.
