Postoperative pain management following minimally invasive abdominal cancer surgeries -An audit.

BACKGROUND: There is limited data comparing pain management following various minimally invasive oncological surgeries (MIOS). This retrospective audit was planned to determine the severity of pain and to study the analgesic modalities offered to these patients. Secondary objectives included studying opioid requirements, non-opioid analgesics, their side effects, and the influence of comorbidities on the choice of pain modalities. METHODS: Following approval and registration of trial (CTRI/2018/10/016220), data were collected retrospectively from adult patients who underwent elective MIOS for abdominal tumors from August 2017 to July 2018. Pain scores (PS) on the day of surgery, and the average, worst PS, and the morphine equivalent (ME) dose in the perioperative period was recorded. Emergency surgeries and thoracic-abdominal MIOS were excluded. The association between the type of surgery, pain modalities, and PS were compared using Chi-square test. ME dose consumption of patients and type of surgery were compared using ANOVA with Bonferroni's correction. RESULTS: Out of the 349 patients' data that were analyzed, 76% had mild, 22% had moderate, and 2% had severe pain after surgery. Port site infiltration was done in 27% of cases and epidural analgesia in 46 patients (13%). PS and opioid consumption (ME = 5.7 ± 5.2 mg) was significantly higher following pelvic surgeries when compared to other urological and diagnostic MIOS. American Society of Anesthesiologists Physical Status did not affect PS or choice of pain management technique. CONCLUSION: Most of the patients experience mild pain at movement in the immediate postoperative period, pelvic MIOS (abdominoperineal resection/exenteration surgeries) have higher PS and opioid consumption than other MIOS.

Referral Pattern to a Tertiary Care Cancer Pain Clinic in India.

The study aimed to identify patterns of patient referral from oncology services, including pain severity, prior analgesics, impact of patient's literacy on referral, and adequacy of pain relief offered by the pain clinic. A retrospective analysis of pain clinic data from August 2014 to February 2015 at the Tata Memorial Hospital was carried out, wherein adult cancer patients referred for the first time to the pain clinic were included. Two thousand patients were included: 38.1% of the referred were at pretreatment stage, 28.8% advanced. Most referrals were from head and neck (27.3%), gastrointestinal (26.2%), and thoracic (18.3%) disease management groups (DMGs); The earliest referrals were from gastrointestinal and thoracic DMGs; 75%-80% had advanced disease. There were few referrals from hemato-oncology and medical oncology. Among the patients, 88% had moderate to severe pain, a third were on analgesics, and less than a fifth were on opioids. Pain scores were lower in the literate group, and this group were referred significantly earlier than the illiterate. Literacy could therefore hold the key to better awareness and compliance with pain management. Our findings demonstrate that pain as yet does not receive a much needed priority even at a tertiary care cancer centre.

The prevalence of severe pain, its etiopathological characteristics and treatment profile of patients referred to a tertiary cancer care pain clinic.

Pain is the most feared symptom in cancer. About 52-77% patients suffer pain despite World Health Organization (WHO) recommendations. Out of total, one-third patients suffer moderate to severe pain. This study was undertaken to determine the prevalence, etiopathogenesis and characteristics of severe pain and treatment response among pain clinic referrals in a busy tertiary care cancer center. This study found a high prevalence (31.5%) of severe pain. A total of 251 patients who had complete pain data were analyzed for etiopathological characteristics and treatment response. Head and neck cancer contributed the highest prevalence among all regions. Oncologists prescribed non-steroidal anti-inflammatory drugs (NSAIDs) or paracetamol with or without mild opioids to 14% patients and pain clinic physicians prescribed opioids and overall 63.7% patients had a better response after pain clinic referral, even then, morphine was not prescribed to many deserving patients. Doctors need pain education about opioids to remove any fear of prescribing opioids in presence of severe pain.

A Prospective, Non-interventional Study of Assessment and Treatment Adequacy of Pain in the Emergency Department of a Tertiary Care Cancer Hospital.

INTRODUCTION: Pain is the most common reason for emergency department (ED) visits by the cancer patients. Treatment inconsistency and inadequacy are reported worldwide in the management of ED pain. We conducted a non-interventional observational study of 100 patients visiting ED with moderate to severe pain in a tertiary care cancer center. AIMS: The goal of this study was to describe the characteristics of pain and its treatment by oncologists in ED. MATERIALS AND METHODS: Management of 100 adult patients with complaints of moderate to severe pain was observed by the investigator in ED. Treatment was provided by the doctors of respective oncological services. Later, patients were interviewed by the investigator to collect data about the details of their pain and treatment adequacy. RESULTS: On arrival to ED, about 65% patients reported severe pain, however no formal pain assessment was performed and no patient received strong opioids. Poor compliance for prescribed analgesic medications was noted in a large number of patients (31%), primarily due to suboptimal pain relief and lack of awareness. Protocol based analgesic treatment was non-existent in ED. Majority of patients remained in significant pain after 30 min of analgesic administration and 24% patients could never achieve more than 50% pain relief at the time of discharge. CONCLUSION: Due to lack of formal pain assessment and laid down protocols, suboptimal pain management is commonly prevalent in ED. Use of strong opioids continues to be scarce in management of severe pain. There is a need to formulate pain management protocols for ED pain.

Development of acute pain service in an Indian cancer hospital.

Postoperative pain relief continues to be a major challenge for all health care professionals caring for such patients in India. Acute pain services are almost nonexistent, even in large private and university hospitals. As per our estimate not more than 10 such services are available. Tata Memorial Hospital is a tertiary care cancer center that started one of the first Acute Pain Services (APS) in India in 2002 to provide safe and effective postoperative pain management. APS guidelines and protocols have since been implemented and patients are monitored by a team of a consultant physician, a nurse, and a medical resident. Audits are done at regular intervals to evaluate the efficacy of service and patient satisfaction. Pain scores declined yet the patient satisfaction has not improved. Postoperative outcome studies are yet to be undertaken. The development and current activities of the APS that can be implemented in a country that does not have sophisticated acute pain management teams are described.

Prevalence, etiology, and management of neuropathic pain in an Indian cancer hospital.

Neuropathic pain is still an under-diagnosed and undertreated problem in third world countries. This retrospective study was undertaken to detect the prevalence, etiology and treatment profile of neuropathic pain in cancer. During January-December 2007, 716 new cancer pain patients were examined in Tata Memorial Hospital Pain Clinic. A total of 180 patients with a mean age of 47.14 yrs were found to have neuropathic pain characteristics on the basis of clinical impression, site of pain and the underlying cause i.e. due to tumor itself or cancer therapy. Head and neck cancer (32.2%) was found to be the most common cause of neuropathic pain, followed by breast (20.6%), thoracic (14.4%), genitourinary or gynecology (10.0% each), GI (9.4%), and medical oncology (2.8%). About 56% patients were post surgery, 44.4% post chemotherapy and 51.1% patients were post radiotherapy. The most common site of pain was thoracic (36.7%) due to primary or secondary metastatic disease. Pricking type of pain was the most characteristic feature (47.8%) followed by shooting pain (38.3%). The mean pain score was 5.96 +/- 1.5 (SD) and mean duration (months) of pain was 2.8 +/- 2.5. Neuropathic pain was found commonly associated with somatic pain (59.4%). The most common pharmacological agents prescribed were: tricyclic antidepressants (93.9%), anticonvulsants (66%), Opioids (85%), and nonsteroidal anti-inflammatory drugs (NSAIDs) (97.2%). Only 35% patients followed up more than once at the pain clinic. The most common and challenging patients were of orofacial pain. Nerve blocks techniques have a limited role in neuropathic pain.

Neurolytic celiac plexus block: a better alternative to opioid treatment in upper abdominal malignancies: an Indian experience.

The majority of patients with advanced upper abdominal malignancies suffer from moderate to severe pain due to unavailability of morphine in developing world. This study was undertaken to evaluate the role of neurolytic celiac plexus block on pain and quality of life in this patient subpopulation. One hundred consecutive patients receiving opioids for their pain relief were divided in two groups. Group I (control) patients received oral morphine & NSAIDS and group II (study) patients underwent neurolytic celiac plexus block (NCPB) to compare their effects on pain relief, morphine consumption, quality of life (QOL), Karnofsky and performance scores up to one month. NCPB provided statistically significant better pain relief and reduced morphine consumption at one month (P = 0.000). Superior Karnofsky and performance scores also favored NCPB group (P = 0.000); however the difference in overall QOL was not statistically significant (P = 0.24). Patients in oral morphine group had more side effects (94% vs. 58%) as compared to NCPB (P = 0.000). NCPB is an effective tool to reduce opioid requirement and the drug-related adverse effects. It is a rewarding technique, especially when morphine availability and its easy accessibility to the deserving patient is poor.

Refractory headache in a patient with breast cancer and carcinomatous meningitis unresponsive to analgesics: case report.

A 44-year old female presented with locally advanced breast cancer that had been treated with neoadjuvant chemotherapy followed by modified radical mastectomy and thereafter three cycles of paclitaxel. She presented with severe refractory headache that was unresponsive to oral analgesics including morphine. Both CT and MRI scans with contrast were normal, however her cerebrospinal fluid was positive for malignant cells. The patient's headache responded to whole brain radiotherapy.

Breakthrough pain characteristics and syndromes in patients with cancer pain. An international survey.

Breakthrough pain (BKP) is a transitory flare of pain that occurs on a background of relatively well controlled baseline pain. Previous surveys have found that BKP is highly prevalent among patients with cancer pain and predicts more severe pain, pain-related distress and functional impairment, and relatively poor quality of life. An international group of investigators assembled by a task force of the International Association for the Study of Pain (IASP) evaluated the prevalence and characteristics of BKP as part of a prospective, cross-sectional survey of cancer pain. Fifty-eight clinicians in 24 countries evaluated a total of 1095 patients with cancer pain using patient-rated items from the Brief Pain Inventory (BPI) and observer-rated measures. The observer-rated information included demographic and tumor-related data, the occurrence of BKP, and responses on checklists of pain syndromes and pathophysiologies. The clinicians reported BKP in 64.8% of patients. Physicians from English-speaking countries were significantly more likely to report BKP than other physicians. BKP was associated with higher pain scores and functional interference on the BPI. Multivariate analysis showed an independent association of BKP with the presence of more than one pain, a vertebral pain syndrome, pain due to plexopathy, and English-speaking country. These data confirm the high prevalence of BKP, its association with more severe pain and functional impairment, and its relationship to specific cancer pain syndromes. Further studies are needed to characterize subtypes of BKP. The uneven distribution of BKP reporting across pain specialists from different countries suggests that more standardized methods for diagnosing BKP are needed.

Respiratory depression following combination of epidural buprenorphine and intramuscular ketorolac.

A 48-year-old man who had undergone thoracotomy for carcinoma of the middle third of his oesophagus developed severe postoperative respiratory depression following intramuscular ketorolac 30 mg 2 h after 150 micrograms epidural buprenorphine. Summation of analgesia by drugs used in combination can have deleterious respiratory effects.

Anthropometry of angles of scapula.

Various angles viz. superior, medial, inferior, inferolateral, lateral, acromial and coracoid were studied in 42 scapulae of right side and 54 scapulae of left side. The angles have no correlation to that of opposite side. The correlation coefficient of each angle in relation to other angles on the same side was studied. Some of the angles showed significant correlation to that of the others.
