Procedure-Specific Pain Intensity Four Days After Day Surgery and the Relationship with Preoperative Pain: A Prospective Cohort Study.

Background: Identification of painful procedures is essential for the development of procedure-specific pain-treatment schedules. The aim of this study was firstly, to analyze the prevalence of acute postsurgical pain (APSP) after various types of day surgery on the fourth postoperative day, and secondly, to assess the predictive value of preoperative pain for the development of APSP after different types of surgical procedures.

Methods: From November 2008 to April 2010, patients scheduled for elective day surgery were enrolled in this prospective cohort study.

Validity and time course of surgical fear as measured with the Surgical Fear Questionnaire in patients undergoing cataract surgery.

Objectives: The primary aim of the study was to assess the convergent validity of the Surgical Fear Questionnaire (SFQ) with other self-report instruments and biological indices of stress. Secondary aims were the examination of predictors of the level and time course of fear and preferences for fear treatment.

Methods: In a prospective observational cohort study SFQ short-term (SFQ-s) and long-term (SFQ-l) scores were assessed one week, one day, and the morning before cataract surgery, together with salivary cortisol and alpha-amylase (sAA) levels, and numeric rating scale (NRS) fear score.

Boundaries of the thoracic paravertebral space: potential risks and benefits of the thoracic paravertebral block from an anatomical perspective.

Purpose: Thoracic paravertebral block (TPVB) may be an alternative to thoracic epidural analgesia. A detailed knowledge of the anatomy of the TPV-space (TPVS), content and adnexa is essential in understanding the clinical consequences of TPVB. The exploration of the posterior TPVS accessibility in this study allows (1) determination of the anatomical boundaries, content and adnexa, (2) description of an ultrasound-guided spread of low and high viscous liquid.

Prevalence and Predictors of Patient Nonadherence to Pharmacological Acute Pain Therapy at Home After Day Surgery: A Prospective Cohort Study.

Background: Good adherence to prescribed analgesics can be crucial to suppress or even prevent acute postoperative pain after day surgery. The aim of this study was to analyze prevalence and predictors of analgesic nonadherence after day surgery.

Methods: Elective patients scheduled for day surgery were prospectively enrolled from November 2008 to April 2010.

Correction: Validation of the Surgical Fear Questionnaire in Adult Patients Waiting for Elective Surgery.

The Influence of Pre- and Postoperative Fear Avoidance Beliefs on Postoperative Pain and Disability in Patients With Lumbar Spinal Stenosis: Analysis of the Lumbar Spinal Outcome Study (LSOS) Data.

Study Design: Prospective multicenter cohort study.

Objective: To evaluate the effect of pre- and postoperatively assessed fear avoidance beliefs (FAB) on pain and disability in patients with degenerative lumbar spinal stenosis (LSS) after decompression surgery.

Summary Of Background Data: To the present, the influence of pre- and postoperative FAB on the prognosis after surgery for LLS is still unclear.

External Validation and Modification of a Predictive Model for Acute Postsurgical Pain at Home After Day Surgery.

Objectives: In 2009, Gramke and colleagues have described predictive factors to preoperatively detect those at risk for moderate to severe acute postsurgical pain (APSP) after day surgery. The aim of the present study is to externally validate this initial model and to improve and internally validate a modified version of this model.

Materials And Methods: Elective patients scheduled for day surgery were prospectively enrolled from November 2008 to April 2010.

Recovery 3 and 12 months after hysterectomy: epidemiology and predictors of chronic pain, physical functioning, and global surgical recovery.

Chronic postsurgical pain (CPSP) is 1 important aspect of surgical recovery. To improve perioperative care and postoperative recovery knowledge on predictors of impaired recovery is essential. The aim of this study is to assess predictors and epidemiological data of CPSP, physical functioning (SF-36PF, 0-100), and global surgical recovery (global surgical recovery index, 0-100%) 3 and 12 months after hysterectomy for benign indication.

Prevalence and Predictors of Quality of Recovery at Home After Day Surgery.

Traditionally, major complications and unanticipated admission/readmission rates were used to assess outcome after day surgery. However, in view of the relative absence of major complications the quality of recovery (QOR) should be considered one of the principal endpoints after day surgery. In our study, the level of QOR is defined by a combination of the Global Surgical Recovery (GSR) Index and the Quality of Life (QOL).

Prevalence and Predictive Factors of Chronic Postsurgical Pain and Poor Global Recovery 1 Year After Outpatient Surgery.

Objectives: To prospectively describe the prevalence and predictive factors of chronic postsurgical pain (CPSP) and poor global recovery in a large outpatient population at a university hospital, 1 year after outpatient surgery.

Materials And Methods: A prospective longitudinal cohort study was performed. During 18 months, patients presenting for preoperative assessment were invited to participate.

Controlled-release oxycodone versus naproxen at home after ambulatory surgery: a randomized controlled trial.

Background: Strong opioids in the home setting after ambulatory surgery have rarely been studied for fear of hazardous adverse effects such as respiratory depression.

Objectives: We compared the efficacy of paracetamol/controlled-release (CR) oxycodone and paracetamol/naproxen for treatment of acute postoperative pain at home after ambulatory surgery. Secondary outcomes were adverse effects of study medication, treatment satisfaction, and postoperative analgesic compliance.

Continuous paravertebral block for postoperative pain compared to general anaesthesia and wound infiltration for major oncological breast surgery.

We hypothesized that improved acute postoperative pain relief will be achieved using general anaesthesia (GA) either in combination with continuous thoracic paravertebral block (GA-cPVB) or single shot (GA-sPVB) as compared to GA supplemented by local wound infiltration (GA-LWI) after unilateral major breast cancer surgery. A randomised controlled trial was conducted in 46 adult women in a day-care or short-stay hospital setting after major breast cancer surgery. Pain-intensity was measured using an 11-point visual analogue scale (VAS) until postoperative day 2.

Validation of the surgical fear questionnaire in adult patients waiting for elective surgery.

Objectives: Because existing instruments for assessing surgical fear seem either too general or too limited, the Surgical Fear Questionnaire (SFQ) was developed. The aim of this study is to assess the validity and reliability of the SFQ.

Methods: Based on existing literature and expert consultation the ten-item SFQ was composed.

Preoperative anxiety and catastrophizing: a systematic review and meta-analysis of the association with chronic postsurgical pain.

Objectives: Anxiety and pain catastrophizing predict acute postoperative pain. However, it is not well established whether they also predict chronic postsurgical pain (CPSP). The aim of this systematic review and meta-analysis was to investigate whether high levels of preoperative anxiety or pain catastrophizing are associated with an increased risk of CPSP.

Predictors of acute postoperative pain after elective surgery.

Objectives: Objectives:Despite efforts to improve acute postoperative pain management, a substantial number of patients still experience moderate to severe pain during the immediate postoperative days. The purpose of the present study was to identify predictors of moderate to severe acute postoperative pain.

Methods: Methods: A total of 1490 patients undergoing heterogeneous surgical procedures recorded their pain 3 times a day on a 100-mm visual analog scale from the day before the operation until 5 days postoperation.

Predictive factors of postoperative pain after day-case surgery.

Objectives: Despite the growing number of ambulatory operations knowledge of predictive factors of postoperative pain after ambulatory surgery is limited. Therefore, the aim of this study was to identify predictive factors of postoperative pain after ambulatory surgery.

Methods: In this cross-sectional study, 648 patients were included.

The prevalence of postoperative pain in a cross-sectional group of patients after day-case surgery in a university hospital.

Objectives: Although a great variety of surgical procedures are performed on an ambulatory basis, little is known about postoperative pain experience at home after ambulatory surgery. This study was performed to assess the prevalence and course of postoperative pain in the early postoperative period after ambulatory surgery.

Methods: Over a period of 4 months, 648 patients who underwent day-case surgery were included in our study.
