Perceived choice of intrathecal morphine (ITM) dose 100 μg compared with 200 μg and post-caesarean delivery pain and side effects. (A and B) Box and whiskers plots representing verbal numerical rating scores (NRSs; scale 0–10) for pain on sitting, where horizontal bar is the mean, top and bottom of the box represent the 25th and 75th percentile values, error bars represent 5 and 95% values, and circles represent outlier values. (A) Patients who preferred a dose of 100-μg ITM for caesarean delivery analgesia had less pain on movement [1.2 (95% CI 0.5–1.9) NRS points] compared with (B) patients who preferred a 200-μg dose of ITM, regardless of dose actually received (P = 0.0008). (C and D) NRS for pruritus. Each line represents the experience of an individual patient during the 48 h after caesarean delivery. A small offset has been introduced to facilitate visualization of the many patients with zero values. (C) Patients who preferred the 100-μg ITM had similar levels of pruritus as compared with (D) those who preferred the 200-μg dose (P = 0.96).

Pharmacologic side effects from the intrathecal morphine (ITM) dose given. Graphs are lines connecting verbal numerical rating scores (NRS; scale 0–10) for nausea (A and B) and pruritus (C and D) indicating the trajectory for each patient. Lines are slightly offset horizontally to allow for visualization of many overlying zero values. (A) Patients who received 200-μg ITM had more nausea compared with (B) patients who received the 100-μg dose {difference in area under the curve [NRS (0–10) × time (hours)] 33 (95% CI 24–43); P = 0.001}. (C) Women who received the 200-μg ITM dose had more pruritus compared with (D) patients who received the 100-μg dose [difference in area under the curve 26 (95% CI 14–109); P < 0.001].
