ABSTRACT
BACKGROUND: Postoperative analgesia after knee arthroplasty forms a basis for an optimal range of motion after surgery. Femoral nerve blocks are established as a sensory nerve blockade but at the expense of quadriceps weakness delaying postoperative mobilization. The adductor canal block (ACB) similarly provides sensory blockade but preserves quadriceps function. If ACB is performed intraoperatively, it would reduce the time and cost needed for ACBs. This study aimed at investigating possible landmarks making it feasible to perform ACB intraoperatively. MATERIAL AND METHODS: Twenty-seven knees were used. The superior pole of the patella, medial epicondyle, and adductor tubercle was proposed as landmarks to perform the ACB through a medial parapatellar approach. A needle was directed toward the adductor tubercle until a tactile feedback was felt. Ten to 15 mL India ink were injected using this technique. The adductor canal was dissected to visualize the ink spread and determine whether the saphenous nerve and the nerve to vastus medialis were exposed to the ink. RESULTS: The anatomic landmarks were easily identified in all knees. The ACB resulted in the saphenous nerve and nerve to vastus medialis being bathed in ink consistently. A volumetric relationship was noted with the injectate. No injury to the neurovascular structures was observed. CONCLUSIONS: An accurate and safe technique with reliable anatomic landmarks was presented to perform an ACB. In addition, an increase in injected ink volume correlated to an increase in the spread of ink; thus, we postulate that 10 mL of local anesthetic may be sufficient for an adequate regional block.
ABSTRACT
INTRODUCTION: Early postoperative complications graded according to the Clavien-Dindo classification system have not previously been correlated with long-term quality of life outcomes in patients who have had restorative proctocolectomy with ileal pouch-anal anastomosis. This study aimed to assess the severity of early postoperative complications and compared these in terms of the long-term quality of life after restorative proctocolectomy in a population-based cohort of patients (operated on from 1984 to 2013). It was hypothesized that those who experienced grade 3 or 4 Clavien-Dindo complications would have worse quality of life at follow-up. METHODS: This population-based study used a combination of a retrospective note review and a cross-sectional questionnaire. All patients with a restorative proctocolectomy performed in 1984-2013 in the Canterbury region were recruited using multiple sources. Early (≤30 days) and late (>30 days) complication rates were obtained via patient records. Early postoperative complications were graded according to the Clavien-Dindo classification. Quality of life was measured using the inflammatory bowel disease questionnaire. RESULTS: One hundred and thirty-six people were identified with a median follow-up of 12 years. Data were available for 121 patients for early complications and 112 for late complications. Eighty-one eligible participants had their quality of life assessed (86% response rate). Early complications occurred in 26% and 76% had late complications. Those who had Clavien-Dindo grade 3 or 4 early complications had lower quality of life scores (P = 0.001) as did females (P = 0.004) and those with a stricture (P = 0.031). CONCLUSION: This population-based study with long-term follow-up demonstrates that Clavien-Dindo grade 3 and 4 postoperative complications are important in determining quality of life in the long term. The reduction in these complications should be a focus of patient management, as it should improve long-term quality of life.
