Expert panel consensus recommendations for postoperative pain management in the Gulf region.

Postoperative pain is a considerable issue in the Gulf region; however, at present there is a lack of comprehensive guidelines addressing postoperative pain management in the region. Therefore, an expert panel of pain specialists convened to address this issue and a set of key recommendations has been developed pertinent to the practice of postoperative pain management in the Gulf region (Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates and Yemen). These recommendations take into consideration the unique variation in cultural, religious and societal beliefs found in the region, as well as varying accessibility to pain medications, thereby aiming to serve as evidence-based guidance on the best practice management of postoperative pain in the Gulf region.

The use of enhanced recovery after surgery (ERAS) principles in Scottish orthopaedic units--an implementation and follow-up at 1 year, 2010-2011: a report from the Musculoskeletal Audit, Scotland.

OBJECTIVE: To establish whether a nationally guided programme can lead to more widespread implementation of enhanced recovery after surgery (ERAS), a well-established optimised care pathway for lower limb arthroplasty. DESIGN: In 2010, National Services Scotland's Musculoskeletal Audit was asked to perform a 'snapshot' audit of the current peri-operative management of patients undergoing total hip and knee arthroplasty in all 22 Scottish orthopaedic units with an identical follow-up audit in 2011 after input and support from the national steering group. POPULATION: Audit 1 and audit 2 involved 1,345 and 1,278 patients, respectively. RESULTS: The number of Scottish units that developed an ERAS programme increased from 8 (36 %) to 15 (68 %). Units that included more ERAS patients had earlier mobilisation rates (146/474, 36 % ERAS patients mobilised same day vs. 34/873, 4 % non-ERAS; n = 22 units, r = 0.55, p = 0.008) and shorter post-operative length of stay (median 4 days vs. ERAS, 5 days non-ERAS, n = 22 units, r = -0.64, p = 0.001). ERAS knee arthroplasty patients had lower blood transfusion rates (5/205, 2 % vs. 51/399, 13 %, n = 22 units, r = -0.62, p = 0.002). Units that restricted the use of IV fluids post-operatively had higher early mobilisation rates (n = 22 units, r = 0.48, p = 0.03) and shorter post-operative length of stay (n = 22 units, r = -0.56, p = 0.007). Reduced use of patient-controlled analgesia was also associated with earlier mobilisation (n = 22 units, r = 0.49, p = 0.02) and shorter length of stay (n = 22 units, r = -0.39, p = 0.07). Urinary catheterisation rates also dropped from 468/1,345 (35 %) in 2010 to 337/1,278 (26 %) in 2011 (n = 22 units, z = 2.19, p = 0.03). CONCLUSION: A clinically guided and nationally supported process has proven highly successful in achieving a further uptake of enhanced recovery principles after lower limb arthroplasty in Scotland, which has resulted in clinical benefits to patients and reduced length of hospital stay.

An audit of pain control pathways following video-assisted thoracoscopic surgery.

OBJECTIVE: To compare different modes of pain management following video-assisted thoracoscopic surgery (VATS) to our national standard. METHODS: This is an audit based on patient's experiences. One hundred consecutive patients who underwent VATS with or without pleurodesis were managed by one of the following pain relief pathways: (A) thoracic paravertebral block + morphine patient-controlled analgesia (PCA), (B) percutaneous thoracic paravertebral catheter +/- morphine PCA, (C) thoracic epidural +/- morphine PCA, (D) morphine PCA alone, and (E) intravenous or subcutaneous morphine as required. Pain score was documented up to four times per day for each patient. The incidence of severe pain was defined as visual analog scale ≥ 7. The results were compared with the standard set by the audit commission for postoperative pain relief in the UK. The mean daily pain scores were calculated retrospectively for all patients. RESULTS: There were no statistically significant differences in mean daily pain scores irrespective of having a pleurodesis. The percentage of patients experiencing severe pain was 34% [mean visual analog scale = 8 (standard deviation = 1.0)]. This was almost seven times the standard. Among these pathways, B had the least percentage incidence of severe pain (16.7%) followed by A (25.0%) D (33.3%), C (35.7%), and E (52.4%). CONCLUSIONS: We are not compliant with the standards set by the audit commission. Pain management in theater recovery needs to be targeted. In the light of these results, we recommend the use of percutaneous thoracic paravertebral catheter +/- morphine PCA for postoperative VATS pain relief.

Femoral nerve block for total knee replacement - a word of caution.

Femoral nerve block (FNB) is a well documented option for post-operative analgesia following major knee surgery. However, motor blockade may be prolonged preventing early mobilisation thereby increasing the length of stay. In addition, as a consequence of persistent quadriceps weakness, patients have an increased risk of falling. We present a series of five patients who underwent total knee replacement with spinal anaesthesia and FNB who fell, sustaining complete wound disruption - including a patient with peri-prosthetic fracture requiring further surgery and prolonged hospital stay. The literature, which is largely in anaesthetic journals, reflects the high quality of analgesia of FNB but makes little or no mention of the delays or dangers in early mobilization. We believe that the potential risks to orthopaedic patients are underestimated.

Aortic valve repair in a patient with congenital afibrinogenemia.

We describe the management of cardiopulmonary bypass (CPB) in a patient with congenital afibrinogenemia (AF). Although this state is akin to the state after hirudin administration, where CPB has been successfully performed, heparinization is still essential to preserve other clotting factors and prevent excessive bleeding. Aprotinin further helps in preservation of clotting factors. There are case reports of thrombosis associated with AF, but aprotinin can be safely used because it is, by definition, an anticoagulant. Cryoprecipitate effectively restores the fibrinogen and produces normal clotting.

The efficacy and safety of three concentrations of levobupivacaine administered as a continuous epidural infusion in patients undergoing orthopedic surgery.

UNLABELLED: We evaluated the efficacy and safety of three concentrations of levobupivacaine infused epidurally as analgesia for patients undergoing orthopedic procedures. Patients undergoing elective hip or knee joint replacement were enrolled in the study (n = 105). Sensory blockade was established preoperatively with 10-15 mL of 0.75% levobupivacaine. Patients were then randomized to receive 0.0625%, 0.125%, or 0.25% levobupivacaine as a continuous epidural infusion at 6 mL/h for 24 h. IV morphine patient-controlled analgesia was given as rescue analgesia, and time to first request for analgesia and total dose of morphine consumed were recorded. Sensory blockade, motor blockade, visual analog scale pain score, and cardiovascular variables were also recorded at regular intervals postoperatively. Ninety-one patients were included in the primary intent-to-treat analysis. Total normalized dose of morphine, number of patient-controlled analgesia requests, and overall postoperative visual analog scale pain scores were significantly lower for the 0.25% group compared with the other two groups, and the time to first request for rescue analgesia was longer. There was no significant difference between the 0.125% and 0.25% groups in terms of maximum motor blockade achieved and time to minimal motor blockade. Safety data were equivalent among the three groups. We conclude that levobupivacaine as a continuous epidural infusion provided adequate postoperative analgesia and that the 0.25% concentration provided significantly longer analgesia than 0.125% or 0.0625% levobupivacaine without any significant increase in detectable motor blockade relative to the 0.125% group. IMPLICATIONS: Postoperative epidural infusion of levobupivacaine can provide safe and effective analgesia for patients having hip or knee joint replacement. Of the three concentrations we infused at a constant rate, 0.25% provided significantly better pain relief.
