Efficacy of Oral Ketamine Combined with Psychotherapy for Treatment Resistant Depression

Background: Treatment resistant depression (TRD) is defined as a major depressive episode that does not improve in response to at least two trials, each of a different class, of antidepressant medication. Pharmacotherapy of TRD with low dose ketamines has been shown as relatively successful in recent studies. Effects of such pharmacotherapy can be augmented by combining ketamine with psychotherapeutic interventions such as Zdyb’s Therapeutic Reset of Internal Processes (TRIP) protocol. Method: 10 adult TRD patients (4 men, 6 women) were treated with low dose ketamines and were also receiving psychotherapeutic intervention as per TRIP protocol. All patients were administered the Patient Health Questionnaire, module 9 (PHQ9) which is a measure of a major depressive episode. The PHQ9 was administered twice: on baseline (i.e., prior to treatment) and after the treatment. Results: On average, our patients fell in the moderate range of severity with respect to symptoms of TRD at baseline (pre-TRIP) as by their mean PHQ9 score of 17.9, (SD = 5.1). Their mean PHQ9 score decreased post TRIP treatment to 9.5 (SD = 6.6): the difference is significant in a t-test, t(10) = 4.3172, p = 0002 (two-tailed). The magnitude of the decrease amounts to 46.9% of the average baseline score. Discussion and Conclusions: Our patients experienced significant reductions in symptoms of TRD in this pilot study. Research studies are now needed with control groups of TRD patients on a waiting list or also of those receiving only the ketamine pharmacotherapy.

Analgesia for the Change of Dressing in Burn Victims: A Comparison Between Oral Ketamine and Oral Dexmedetomidine

Objective: To compare the efficacy of oral ketamine with oral dexmedetomidine for providing adequate analgesia for change of dressing in burn patients in burn dressing room. Methods: This randomized controlled trial was carried out in Jinnah Burn and Reconstructive Surgery Center, Lahore, from April 2019 to September 2019 after getting the approval from the Ethical Committee of Jinnah Hospital / Allama Iqbal Medical College, Lahore. 80 patients between 20 to 50 years, with 1st and 2nd degree burns and 20 to 40% of total body surface area involved were allocated in two groups A and B. The patients in group A received oral ketamine at a dose of 5mg/kg in 15 ml of water 30 mins while those in group B received dexmedetomidine, 4 ug/kg orally, in 15 ml of water 30 mins before the start of dressing change. The change of dressing was carried out with continuous vital monitoring. Pain was assessed via visual analogue scale (VAS) and sedation via Ramsay sedation score. All the observations were recorded on the predesigned proforma. SPSS version 21 was used for data analysis. Result: The baseline mean VAS score of patients in group A was 7.67 + 0.55 and in group B was 7.70 + 0.57 (p value = 0.799). Significant decrease in pain score in both groups was noted after 30 mins of drugs administration (p=0.000). Also a significant difference in pain scores was seen between the two groups (p< 0.05), with the patients in group A having lower pain scores as compared to patients in group B. Conclusion: both ketamine and dexmedetomidine provide adequate analgesia for the change of burn dressing when administered orally with ketamine providing better analgesic state as compared to dexmedetomidine. Key Words: Burn, ketamine, dexmedetomidine, analgesia. How to cite: Sohail F., Bangash R.L., Azim W., Arshad F, Anwar A., Niazi K.A.

Low dose oral ketamine treatment in chronic suicidality: An open-label pilot study

Recently, low-dose ketamine has been proposed as a rapid-acting treatment option for suicidality. The majority of studies to date have utilised intravenous (IV) ketamine, however, this route of administration has limitations. On the other hand, oral ketamine can be administered in a range of settings, which is important in treating suicidality, although studies as to safety and feasibility are lacking. n = 32 adults (aged 22–72 years; 53% female) with chronic suicidal thoughts participated in the Oral Ketamine Trial on Suicidality (OKTOS), an open-label trial of sub-anaesthetic doses of oral ketamine over 6 weeks. Participants commenced with 0.5 mg/kg of ketamine, which was titrated to a maximum 3.0 mg/kg. Follow-up assessments occurred at 4 weeks after the final dose. The primary outcome measure was the Beck Scale for Suicide Ideation (BSS) and secondary measures included scales for suicidality and depressive symptoms, and measures of functioning and well-being. Mean BSS scores significantly reduced from a high level of suicidal ideation at the pre-ketamine (week 0) timepoint to below the clinical threshold at the post-ketamine (week 6) timepoint. The proportion of participants that achieved clinical improvement within the first 6 weeks was 69%, whereas 50% achieved a significant improvement by the follow-up (week 10) timepoint. Six weeks of oral ketamine treatment in participants with chronic suicidality led to significant reduction in suicidal ideation. The response observed in this study is consistent with IV ketamine trials, suggesting that oral administration is a feasible and tolerable alternative treatment for chronic suicidality.

A Randomised Controlled Trial on the Efficacy and Safety of Oral Ketamine in Neonatal Circumcision

Introduction: Procedural analgesia use in neonatal circumcision is not widespread in the developing world. An easy-to-administer, adequate and safe analgesia will encourage usage in neonatal circumcision. Orally administered ketamine may prove effective and safe, and may encourage procedural analgesia use in neonatal circumcision. Aim: To determine the analgesic efficacy of oral ketamine in Plastibell® neonatal circumcision. Materials and Methods: A hospital based randomised double blind controlled study was conducted at the paediatric surgery unit of the hospital, from March 2015 to December 2015. Total 121 neonates were sequentially recruited, and randomised into two groups. Group A received oral ketamine, and Group B received plain syrup (placebo) as procedural analgesia. Continuous pulse oximeter monitoring was done before, during and immediately after the procedure. The pre-procedural and intra-procedural peripheral oxygen saturation (SpO2) and Pulse Rate (PR) were determined at the various stages. Also, the Neonatal Infant Pain Scale (NIPS) scores were assessed during the stages of the procedure. Differences in mean scores were analysed. Mann-Whitney U test and Independent t-test were used to compare means of continuous variable, while Fisher’s exact test was used to compare categorical variables. Significance was set at p<0.05. Results: Sixty-one neonates received oral ketamine, while 60 received placebo. The intraoperative mean SpO2 were lower in the placebo group and significant at the tying stage with p=0.022. The mean intraoperative PR was higher in the placebo group and significant at dorsal-slit, tying and excision stages (p<0.05). The mean intraoperative NIPS scores were significantly higher in the placebo group. Conclusion: Oral ketamine provides effective and safe analgesia for neonatal Plastibell® circumcision in comparison to placebo.
