Brief summary (from the registry)
Perioperative serum potassium in patients over 65 impacts recovery, quality of life and physical functioning. While perioperative serum potassium is an important preoperative risk factor for poor surgical outcomes in older adults, the relationship between perioperative serum potassium and postsurgical pain in this population has not been investigated. The investigators hypothesized that preoperative serum potassium would be associated with greater odds of postsurgical chronic pain.

Eligibility criteria
Show eligibility criteria (verbatim from the registry)
Inclusion Criteria: * Geriatric surgical patients ≥65 years old * Diagnosis of Chronic postsurgical pain (CPSP) CPSP was made based on the guidelines of the International Society for Pain (CPSP: ICD-11) as follows: Chronic postsurgical pain is chronic pain developing or increasing in intensity after a surgical procedure and persisting beyond the healing process, i.e. at least 3 months after surgery. The pain is either localised to the surgical field, projected to the innervation territory of a nerve situated in this area, or referred to a dermatome (after surgery/injury to deep somatic or visceral tissues). Other causes of pain including infection, malignancy etc. need to be excluded as well as pain continuing from a pre-existing pain problem. Dependent on type of surgery, chronic postsurgical pain often may be neuropathic pain. Exclusion Criteria: * Patients in the central nervous system group were excluded from cardiac and neurosurgery, patients in the heart injury group were excluded from cardiac surgery. * patients who did not agree to participate in the study were excluded in all groups.
